Add Messaging, Voice, and Authentication to your apps with Vonage Communications APIs
Visit the Vonage API Developer PortalUse the OpenTok REST API to generate OpenTok sessions, to work with archives, and to work with live streaming broadcasts. The OpenTok server SDKs (for Java, .NET, Node.js, PHP, Python, and Ruby) implement many of the methods of the REST API.
The REST API includes methods for the following:
Session creation, signaling, and moderation
Archiving
SIP interconnect
Live streaming broadcasts
Experience Composer
Account management
The OpenTok SDKs wrap the OpenTok REST API to make it easier to make calls to the OpenTok platform.
REST API calls must be authenticated using a custom HTTP header —
X-OPENTOK-AUTH — along with a
JSON web token. Create the JWT token with the following claims:
{
"iss": "your_api_key",
"ist": "project",
"iat": current_timestamp_in_seconds,
"exp": expire_timestamp_in_seconds,
"jti": "jwt_nonce"
}
Set iss to your OpenTok API key. For most REST API calls, use the
API key for the specific project in your account. This is provided on the
Project page of your Video API account.
However, the following REST methods are restricted to registered administrators
for the OpenTok account. To use these methods, you must set iss to the
account-level API key, which is only available to account administrators.
(see Account Management):
To obtain the account-level API key and secret, log on to your Video API account, click Account Settings in the left-hand menu, and then under OpenTok REST API, click View account keys.
For most REST API calls, set ist to "project". However, for the following
Account Management REST methods, set
ist to "account":
Set iat to the current Unix epoch timestamp (when the token was created), in seconds.
Set exp to the expiration time for the token. For security,
we recommend that you use an expiration time close to the token creation time (for example,
3 minutes after creation) and that you create a new token for each REST API call. The maximum
allowed expiration time range is 5 minutes.
Set jti to a unique identifier for the JWT. This is optional. See the
JSON web token spec for details.
Use your OpenTok API secret as the JWT secret key and sign this with the HMAC-SHA256 encryption algorithm. For most REST API calls, use the API secret for the specific project in your account. This is provided on the Project page of your Video API account. However, the following REST methods are restricted to registered administrators for the OpenTok account. To use these methods, you must use the account-level API key and secret (which is only available to account administrators) as the JWT secret key (see Account Management):
For example, the following Python code creates a token that can be used in an OpenTok REST API call:
import jwt # See https://pypi.python.org/pypi/PyJWT
import time
import uuid
print jwt.encode({"iss": "my-OpenTok-API-key",
"iat": int(time.time()),
"exp": int(time.time()) + 180,
"ist": "project",
"jti": str(uuid.uuid4())},
'my-OpenTok-API-secret',
algorithm='HS256')
Replace the my-OpenTok-API-key and my-OpenTok-API-secret
with the OpenTok API key and API secret.
Note: Prior to using JSON Web Tokens, OpenTok REST API calls were authenticated
using a custom HTTP header: X-TB-PARTNER-AUTH with the value set to your OpenTok API key and
API secret concatenated with a colon:
X-TB-PARTNER-AUTH: <api_key>:<partner_secret>
However, this form of authentication (using X-TB-PARTNER-AUTH) is deprecated,
and you should now use JSON Web tokens for authentication. (Use of this deprecated form of
authentication will expire in July 2017.)
Generate a new session.
https://api.opentok.com/session/create
POST
API calls must be authenticated using a custom HTTP header — X-OPENTOK-AUTH
— along with a JSON web token (JWT). See Authentication.
Set the Content-Type header to application/x-www-form-urlencoded:
Content-Type:application/x-www-form-urlencodedSet the Accept header to application/json:
Accept:application/jsonarchiveMode
Set to always to have the session archived automatically. With the
archiveModeset to manual (the default), you can archive the session by
calling the REST /archive POST method. If you set the archiveMode to
always, you must also set the p2p.preference parameter to
disabled (the default).
locationThe IP address that the Vonage Video APi will use to situate the session in its global network. If no location hint is passed in (which is recommended), the session uses a media server based on the location of the first client connecting to the session. Pass a location hint in only if you know the general geographic region (and a representative IP address) and you think the first client connecting may not be in that region. Specify an IP address that is representative of the geographical location for the session.
p2p.preference
Set to enabled if you prefer clients to attempt to send audio-video streams
directly to other clients; set to disabled for sessions that use the OpenTok Media
Router. (Optional; the default setting is disabled -- the session uses
the OpenTok Media Router.)
The OpenTok Media Router provides the following benefits:
enabled, each client must send
a separate audio-video stream to each client subscribing to it.)
With the p2p.preference property set to "enabled", the session
will attempt to transmit streams directly between clients. If clients cannot connect
due to firewall restrictions, the session uses the OpenTok TURN server to relay
audio-video streams.
POST /session/create HTTP/1.1
Host: https://api.opentok.com
X-OPENTOK-AUTH: json_web_token
Accept:application/json
location=10.1.200.30&p2p.preference=disabled
The following command line example creates a session that uses the OpenTok Media Router and specifies a location hint:
export TB_url=https://api.opentok.com/session/create
json_web_token="jwt_string" # replace with a JSON web token (see "Authentication")
datastr="location=10.1.200.30"

$TB_url
The following command line example creates a session that attempts to transmit streams directly between clients (without using the OpenTok Media Router):
export TB_url=https://api.opentok.com/session/create
json_web_token="jwt_string" # replace with a JSON web token (see "Authentication")
datastr="p2p.preference=enabled"

-H "Accept:application/json" \
-H "X-OPENTOK-AUTH:$json_web_token" \
-d $datastr \
$TB_url
The following command line example creates an automatically-archived session:
export TB_url=https://api.opentok.com/session/create
json_web_token="jwt_string" # replace with a JSON web token (see "Authentication")
datastr="archiveMode=always"
curl \
-X POST \

-H "Accept:application/json" \
-H "X-OPENTOK-AUTH:$json_web_token" \
-d $datastr \
$TB_url
The response is JSON data of the following form:
[
{
"session_id": "the session ID",
"project_id": "your OpenTok API key",
"create_dt": "The creation date",
"media_server_url": "The URL of the OpenTok media router used by the session -- ignore this"
}
]
Note that if you do not include the "Accept:application/json" header, the response format is XML. This XML version of the API call is deprecated.
The HTTP response has a 403 status code if you pass in an invalid OpenTok API key or JWT token.
The HTTP response has a 500 status code for an OpenTok server error.
Use the Signal REST API to send signals to all participants in an active
OpenTok session or to a specific client connected to that session. Signals
sent from the server have an empty from parameter in the signal received
handlers on clients connected to the session. For a signal sent from a
participant in the session, the from property is set the connection ID of
the client that sent the signal, but in this case there is no associated
connection.
For both signal examples below, the request body will be used to forward both
the type and data fields. These correspond to the type and data parameters
passed in the client signal received handlers.
Send an HTTP POST to the signal resource of the session:
SESSION_ID=SOMESESSIONID
API_KEY=123456
JWT=jwt_token # replace with a JSON web token (see "Authentication")
DATA='{"type":"foo","data":"bar"}'
curl -v \
-H "Content-Type: application/json" \
-X POST \
-H "X-OPENTOK-AUTH:${JWT}" \
-d "${DATA}" \
https://api.opentok.com/v2/project/${API_KEY}/session/${SESSION_ID}/signal
Note: Previously, this REST URL used /partner (which is now deprecated)
instead of /project.
Send an HTTP POST to the signal resource of a specific connection ID,
belonging to the session:
SESSION_ID=SOMESESSIONID
CONNECTION_ID=SOMECONNECTIONID
API_KEY=123456
JWT=jwt_token # replace with a JSON web token (see "Authentication")
DATA='{"type":"foo","data":"bar"}'
curl -v \
-H "Content-Type: application/json" \
-X POST \
-H "X-OPENTOK-AUTH:${API_KEY}:${API_SECRET}" \
-d "${DATA}" \
https://api.opentok.com/v2/project/${API_KEY}/session/${SESSION_ID}/connection/${CONNECTION_ID}/signal
Errors be returned in the response as HTTP Status Codes:
400 — One of the signal properties — data, type, sessionId
or connectionId — is invalid.403 — You are not authorized to send the signal. Check your
authentication credentials.404 — The client specified by the connectionId property is not
connected to the session.413 — The type string exceeds the maximum length (128 bytes), or the
data string exceeds the maximum size (8 kB).In an error case, the response body will look like this:
{
"code" : 400,
"message" : "One of the signal properties — data, type, sessionId or connectionId — is invalid."
}Your application server can disconnect a client from an OpenTok session by sending an HTTP DELETE request to the resource for that client's connection:
SESSION_ID=SOMESESSIONID
CONNECTION_ID=SOMECONNECTIONID
API_KEY=123456
JWT=jwt_token # replace with a JSON web token (see "Authentication")
curl -v \
-X DELETE \
-H "X-OPENTOK-AUTH:${JWT}" \
https://api.opentok.com/v2/project/${API_KEY}/session/${SESSION_ID}/connection/${CONNECTION_ID}
Note: Previously, this REST URL used /partner (which is now deprecated)
instead of /project.
Errors be returned in the response as HTTP Status Codes:
400 — One of the arguments — sessionId or connectionId
— is invalid.403 — You are not authorized to forceDisconnect, check your
authentication credentials.404 — The client specified by the connectionId property is not
connected to the session.In an error case, the response body will look like this:
{
"code" : 404,
"message" : "Connection not found."
}Use this method to get information on an OpenTok stream (or all streams in a session).
For example, you can call this method to get information about layout classes used by an OpenTok stream. The layout classes define how the stream is displayed in the layout of a broadcast stream. For more information, see Assigning live streaming layout classes to OpenTok streams.
To get layout class information for a specific stream, submit an HTTP GET request to the following URL:
https://api.opentok.com/v2/project/<apiKey>/session/<sessionId>/stream/<streamId>
Replace <apiKey> with your OpenTok API key.
Replace <sessionId> with the session ID.
Replace <streamId> with the stream ID.
To get layout class information for all streams in a session, submit an HTTP GET request to the following URL (leaving out the stream ID at the end):
https://api.opentok.com/v2/project/<apiKey>/session/<sessionId>/stream/
Authenticate this API call using a custom HTTP header — X-OPENTOK-AUTH —
set to a JSON web token. See Authentication.
When getting layout class info for a single stream, the response's JSON data includes a layoutClassList array:
{
"id": "8b732909-0a06-46a2-8ea8-074e64d43422",
"videoType": "camera",
"name": "",
"layoutClassList": ["full"]
}layoutClassList property is an array of the layout classes for the stream.id property is the stream ID.videoType property is set to "camera", "screen", or "custom". A "screen" video
uses screen sharing on the publisher as the video source; a "custom" video is published
by a web client using an HTML VideoTrack element as the video source.name property is the stream name (if one was set when the client published the stream).When getting layout class info for a multiple streams, the response's JSON data includes an items
property, which is array containing layout information for streams in the session:
{
"count": 2
"items": [
{
"id": "8b732909-0a06-46a2-8ea8-074e64d43422",
"videoType": "camera",
"name": "",
"layoutClassList": ["full"]
},
...
]
}The HTTP response will have one of the following status codes:

Submit an HTTP POST request to the following URL:
https://api.opentok.com/v2/project/<api_key>/session/<session_id>/stream/<stream_id>/mute
Replace <api_key> with the OpenTok project API key (see the Project Page of your
Video API account). Replace <session_id> with the session ID of the
session containing the stream. Replace <stream_id> with the stream ID.
Authenticate this API call using a custom HTTP header — X-OPENTOK-AUTH:
X-OPENTOK-AUTH:<token>
Set this header to a JWT token (see Authentication).
The HTTP response will have one of the following status codes:
200 — Success. The response data is a project details object.
400 — Invalid request.
403 — Authentication error.
404 — Not found. The session or stream is not found.
500 — OpenTok server error.

Set the Content-Type header to application/json.
Authenticate this API call using a custom HTTP header — X-OPENTOK-AUTH:
X-OPENTOK-AUTH:<token>
Set this header to a JWT token (see Authentication).
Include a JSON object of the following form as the request body content:
{
"active": true,
"excludedStreamIds": [
"excludedStreamId1",
"excludedStreamId2"
]
}The JSON data includes the following properties:
active (Boolean, required) — Whether to mute streams in the session (true)
and enable the mute state of the session, or to disable the mute state of the session (false).
With the mute state enabled (true), all current and future streams published to
the session (with the exception of streams in the excludedStreamIds array) are muted.
When you call this method with the active property set to false, future streams published
to the session are not muted (but any existing muted streams remain muted).
excludedStreamIds (Array of strings, optional) — The stream IDs for streams that should
not be muted. This is an optional property. If you omit this property, all streams in the session
will be muted. This property only applies when the active property is set to true.
When the active property is set to false, it is ignored.
The elements in the excludedStreamIds array are stream IDs (strings) for the streams you wish
to exclude from being muted.
If you do not wish to include an array of excluded streams, do not include any body content.
The HTTP response will have one of the following status codes:
200 — Success. The response data is a project details object.
400 — Invalid request. This response may indicate that data in your request data is invalid JSON.
403 — Authentication error.
404 — Not found. The session is not found.
500 — OpenTok server error.

https://api.opentok.com/v2/project/${API_KEY}/session/${SESSION_ID}/muteTo start recording an archive of an OpenTok session, submit an HTTP POST request.
To successfully start recording an archive, at least one client must be connected to the session.
You can only record archives of sessions that use the OpenTok Media Router (with the media mode set to routed); you cannot archive sessions that have the media mode set to relayed. (See The OpenTok Media Router and media modes.)
For more information, see the OpenTok archiving developer guide.
Submit an HTTP POST request to the following URL:
https://api.opentok.com/v2/project/<api_key>/archive
Replace <api_key> with your OpenTok API key. See the Project Page of your Video API account.
Note: Previously, this REST URL used /partner (which is now deprecated)
instead of /project.
API calls must be authenticated using a custom HTTP header — X-OPENTOK-AUTH
— along with a JSON web token (JWT). See Authentication.
Set the Content-type header to application/json:
Content-Type:application/json
Include a JSON object of the following form as the POST data:
{
"sessionId" : "session_id",
"hasAudio" : true,
"hasVideo" : true,
"layout" : {
"type": "custom",
"stylesheet": "the layout stylesheet (only used with type == custom)",
"screenshareType": "the layout type to use when there is a screen-sharing stream (optional)"
},
"name" : "archive_name",
"outputMode" : "composed",
"resolution" : "640x480",
"streamMode" : "auto"
}
The JSON object includes the following properties:
sessionId (String) — (Required) The session ID of the OpenTok session you want to start archivinghasAudio (Boolean) — (Optional) Whether the archive will record audio
(true, the default) or not (false). If you set both hasAudio and
hasVideo to false, the call to this method results in an error.hasVideo (Boolean) — (Optional) Whether the archive will record video
(true, the default) or not (false). If you set both hasAudio and
hasVideo to false, the call to this method results in an error.layout (Object) — Optional. Specify this to assign the initial layout type for
the archive. This applies only to
composed
archives. This object has three properties: type, stylesheet,
and screenshareType, which are each strings. Valid values for the
layout property are "bestFit"
(best fit), "custom" (custom), "horizontalPresentation"
(horizontal presentation), "pip" (picture-in-picture), and
"verticalPresentation" (vertical presentation)). If you specify a
"custom" layout type, set the stylesheet property of the
layout object to the stylesheet. (For other layout types, do not set a
stylesheet property.) Set the screenshareType property to
the layout type to use when there is a screen-sharing stream in the session.
(This property is optional.) Note if you set the screenshareType property,
you must set the type property to "bestFit" and leave the
stylesheet property unset. If you do not specify an initial layout type,
the archive uses the best fit layout type. For more information, see
Customizing the video layout for composed archives.
multiArchiveTag (String) — (Optional) Set this to support recording multiple
archives for the same session simultaneously. Set this to a unique string for each simultaneous
archive of an ongoing session. You must also set this option when manually starting an archive
in a session that is automatically archived.
If you do not specify a unique
multiArchiveTag, you can only record one archive at a time for a given session. See
Simultaneous archives.
name (String) — (Optional) The name of the archive (for your own
identification). The maximum length of the archive name is 255 characters.outputMode (String) — (Optional) Whether all streams in the archive are
recorded to a single file ("composed", the default) or to individual files
("individual"). See
Individual stream
and composed archives.resolution (String) — (Optional) The resolution of the archive,
either "640x480" (SD landscape, the default), "1280x720" (HD landscape),
"1920x1080" (FHD landscape), "480x640" (SD portrait),
"720x1280" (HD portrait), or "1080x1920" (FHD portrait). You may
want to use a portrait aspect ratio for archives that include video streams
from mobile devices (which often use the portrait aspect ratio). This property
only applies to composed archives. If you set this property and set the outputMode
property to "individual", the call to the REST method results in an error.streamMode (String) — (Optional) Whether streams included in the archive are
selected automatically ("auto", the default) or manually ("manual").
When streams are selected automatically ("auto"), all streams in the session
can be included in the archive. When streams are selected manually ("manual"),
you specify streams to be included based on calls to this
REST method. You can specify whether a stream's audio, video, or both are included in the archive.
In composed archives, in both automatic and manual modes, the archive composer includes streams
based on
stream prioritization rules.
The raw data of the HTTP response, with status code 200, is a JSON-encoded message of the following form:
{
"createdAt" : 1384221730555,
"duration" : 0,
"hasAudio" : true,

}
The JSON object includes the following properties:
createdAt — The timestamp for when the archive started recording, expressed in milliseconds since the Unix epoch
(January 1, 1970, 00:00:00 UTC).hasAudio — Whether the archive will record audio (true) or not (false).hasVideo — Whether the archive will record video (true) or not (false).id — The unique archive ID. Store this value for later use (for example, to stop the recording).multiArchiveTag — The unique tag for simultaneous archives (if one was set).name — The name of the archive you supplied (this is optional).outputMode — Either "composed" or "individual". See
Individual stream
and composed archives.projectId — Your OpenTok API key.resolution — The resolution of the archive (either "640x480", "1280x720",
"1920x1080", "480x640", "720x1280", or "1080x1920"). This property is only set for composed archives.sessionId — The session ID of the OpenTok session being archived.status — This is set to "started".streamMode — Whether streams included in the archive are
selected automatically ("auto", the default) or manually ("manual").
streams — An array of objects corresponding to streams currently being
archived. This is only set for an archive with the status set to "started"
and the streamMode set to "manual". Each
object in the array includes the following properties:
streamId — The stream ID of the stream included in the archive.
hasAudio — Whether the stream's audio is included in the archive.
hasVideo — Whether the stream's video is included in the archive.
The HTTP response has a 400 status code in the following cases:
resolution value.outputMode property is set to "individual" and
you set the resolution property and (which is not supported in individual
stream archives).The HTTP response has a 403 status code if you pass in an invalid OpenTok API key or JWT token.
The HTTP response has a 404 status code if the session does not exist, or if the session exists but there are no clients connected to it.
The HTTP response has a 409 status code if you attempt to start an archive for a session that
does not use the OpenTok Media Router. Or if you attempt to start an archive for a session that
is already being recorded without setting the multiArchiveTag option. Or if you attempt
to start a simultaneous archive for a session without setting a unique multiArchiveTag
value.
The HTTP response has a 500 status code for an OpenTok server error.

Archives stop recording after 4 hours (14,400 seconds), or 60 seconds after the last client disconnects from the session, or 60 minutes after the last client stops publishing. However, automatic archives continue recording to multiple consecutive files of up to 4 hours in length each. For more information, see Archive duration
Calling this method for automatic archives has no effect. Automatic archives continue recording to multiple consecutive files of up to 4 hours (14,400 seconds) in length each, until 60 seconds after the last client disconnects from the session, or 60 minutes after the last client stops publishing a stream to the session.
Submit an HTTP POST request to the following URL:
https://api.opentok.com/v2/project/<api_key>/archive/<archive_id>/stop
Replace <api_key> with your OpenTok API key. See your Project Page on your Video API account.
Replace <archive_id> with the archive ID. You can obtain the archive ID from the response to the API call to
start recording the archive.

start recording the archive.To list archives for your API key, both completed and in-progress, submit an HTTP GET request.
Note: Archive records are available for up to 12 months.
Submit an HTTP GET request to the following URL:
https://api.opentok.com/v2/project/<api_key>/archiveReplace <api_key> with your OpenTok API key. See the Project Page in your Video API account.
Note: Previously, this REST URL used /partner (which is now deprecated)
instead of /project.
You can add query parameters to filter the results (these are optional):
Set an offset query parameters to specify the index offset of the first archive. 0 is offset of
the most recently started archive (excluding deleted archive). 1 is the offset of the archive
that started prior to the most recent archive. The default value is 0.
Set a count query parameter to limit the number of archives to be returned. The default
number of archives returned is 50 (or fewer, if there are fewer than 50 archives). The maximum
number of archives the call will return is 1000.
Set a sessionId query parameter to list archives for a specific session ID.
(This is useful when listing multiple archives for an automatically archived
session.)
For example the following call specifies a count and offset values:
https://api.opentok.com/v2/project/<api_key>/archive?offset=400&count=20The following call specifies a (fake) sessionId value:
https://api.opentok.com/v2/project/<api_key>/archive?sessionId=2_MX4xMDB-flR1-QxNzIxNX4Deleted archives are not included in the results of this API call.
Replace <api_key> with your OpenTok API key. See the Project Page in your Video API account.

Note: You can also set an archive upload target on your Vonage Video API account page.
For Amazon S3, you will need to provide Vonage with upload-only permission to the Amazon S3 bucket. If you want to use an S3 IAM user, assign it the following user policy:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmt1",
"Effect": "Allow",
"Resource": [ "arn:aws:s3:::<your-bucket-name>/*" ],
"Action": [

"s3:ListBucket"
]
},
{
"Sid": "Stmt2",
"Effect": "Allow",
"Resource": [ "arn:aws:s3:::*" ],
"Action": [
"s3:ListAllMyBuckets"
]
}
]
}To set an archive upload target, submit an HTTP PUT request.
If you set an upload target, each completed archive file is uploaded as a file
named archive.mp4 in the path /projectKey/archiveId/ of the target bucket,
where projectKey is the project API key, and archiveId is the archive ID.
If you have already set an archive upload target for a project's archive files, you can submit another PUT request to register a new upload target.
For more information on archiving, see the archiving programming guide.
Submit an HTTP PUT request to the following URL:
https://api.opentok.com/v2/project/<api_key>/archive/storage

To connect your SIP platform to an OpenTok session, submit an HTTP POST request to the
dial method. The audio from your end of the SIP call is added to the OpenTok session
as an audio-only stream. The OpenTok Media Router mixes audio from other streams in the session and
sends the mixed audio to your SIP endpoint.
The call ends when your SIP server sends a BYE message (to terminate the call).
You can also end a call using the OpenTok REST API method to
disconnect a client from a session. The OpenTok SIP
gateway automatically ends a call after 5 minutes of inactivity (5 minutes without media received).
Also, as a security measure, the OpenTok SIP gateway closes any SIP call that lasts longer than
6 hours.
The SIP interconnect feature requires that you use an OpenTok session that uses the OpenTok Media Router (a session with the media mode set to routed).
For more information, including technical details and security considerations, see the OpenTok SIP interconnect developer guide.
Submit an HTTP POST request to the following URL:
https://api.opentok.com/v2/project/<api_key>/dial
Replace <api_key> with your OpenTok API key. See the Project Page of your
Video API account.
Note: Previously, this REST URL used /partner (which is now deprecated)
instead of /project.
API calls must be authenticated using a custom HTTP header — X-OPENTOK-AUTH
— along with a JSON web token (JWT). See Authentication.
Set the Content-type header to application/json:
Content-Type:application/json
Include a JSON object of the following form as the POST data:
{
"sessionId": "OpenTok session ID",
"token": "A valid OpenTok token",
"sip": {
"uri": "sip:user@sip.partner.com;transport=tls",
"from": "from@example.com",
"headers": {
"headerKey": "headerValue"
},
"auth": {
"username": "username",
"password": "password"
},
"secure": true|false,
"video": true|false,
"observeForceMute": true|false
}
}
The JSON object includes the following properties:
sessionId (required) — The OpenTok session ID for the SIP call to join.
token (required) — The OpenTok token to be used for the participant being
called. You can add token data to identify that the participant is on a SIP
endpoint or for other identifying data, such as phone numbers. (The OpenTok client libraries
include properties for inspecting the connection data for a client connected to a session.) See
the Token Creation developer guide.
uri (required) — The SIP URI to be used as destination of the SIP call
initiated from OpenTok to your SIP platform.
If the SIP uri contains a transport=tls header, the negotiation
between Vonage and the SIP endpoint will be done securely. Note that this will only apply to the
negotiation itself, and not to the transmission of audio. If you also audio transmission to be
encrypted, set the secure property to true.
This is an example of secure call negotiation:
"sip:user@sip.partner.com;transport=tls"This is an example of insecure call negotiation:
"sip:user@sip.partner.com"from (optional): The number or string that will be sent to the final SIP number
as the caller. It must be a string in the form of from@example.com, where
from can be a string or a number. If from is set to a number (for example, "14155550101@example.com"), it will show up as the incoming number on
PSTN phones. If from is undefined or set to a string (for example,
"joe@example.com"), +00000000 will show up as the incoming number on PSTN phones.
headers (optional) — This object defines custom headers to be added to
the SIP INVITE request initiated from OpenTok to your SIP platform.
auth (optional) — This object contains the username and password to be
used in the the SIP INVITE request for HTTP digest authentication, if it is required
by your SIP platform.
secure (optional) — A Boolean flag that indicates whether the media must be
transmitted encrypted (true) or not (false, the default).
video (optional) — A Boolean flag that indicates whether the SIP call will include video
(true) or not (false, the default). With video included,
the SIP client's video is included in the OpenTok stream that is sent to the OpenTok session. The SIP client
will receive a single composed video of the published streams in the OpenTok session.
observeForceMute (optional) A boolean flag that indicates whether the SIP end point observes
force mute moderation (true) or not
(false, the default). Also, with observeForceMute set to true,
the caller can press "*6" to unmute and mute the published audio. For the "*6" mute toggle to work,
the SIP caller must negotiate RFC2833 DTMFs (RFC2833/RFC4733 digits). The mute toggle is not supported
with SIP INFO or in-band DTMFs. A message (in English) is played to the caller when the caller mutes
and unmutes, or when the SIP client is muted through a force mute action.
The raw data of the HTTP response, with status code 200, is a JSON-encoded message of the following form:
{
"id": "b0a5a8c7-dc38-459f-a48d-a7f2008da853",
"connectionId": "e9f8c166-6c67-440d-994a-04fb6dfed007",
"streamId": "482bce73-f882-40fd-8ca5-cb74ff416036",
}
The JSON object includes the following properties:
id — A unique ID for the SIP call.
connectionId — The OpenTok connection ID for the SIP call's connection in the
OpenTok session. You can use this connection ID to terminate the SIP call, using the OpenTok
REST API.
streamId — The OpenTok stream ID for the SIP call's stream in the
OpenTok session.
The HTTP response has a 400 status code in the following cases:
The HTTP response has a 403 status code if you pass in an invalid OpenTok API key or an invalid JSON web token.
The HTTP response has a 404 status code if the session does not exist.
The HTTP response has a 409 status code if you attempt to start a SIP call for a session that does not use the OpenTok Media Router.
The HTTP response has a 500 status code for an OpenTok server error.

https://api.opentok.com/v2/project/${API_KEY}/session/${SESSION_ID}/connection/${CONNECTION_ID}/play-dtmfUse this method to start a live streaming broadcast for an OpenTok session. This broadcasts the session to an HLS (HTTP live streaming) or to RTMP streams.
To successfully start broadcasting a session, at least one client must be connected to the session.
The live streaming broadcast can target one HLS endpoint and up to five RTMP servers simultaneously for a session. You can only start live streaming for sessions that use the OpenTok Media Router (with the media mode set to routed); you cannot use live streaming with sessions that have the media mode set to relayed. (See The OpenTok Media Router and media modes.)
For more information about OpenTok live streaming, see the Broadcast developer guide.
Submit an HTTP POST request to the following URL:

Include a JSON object of the following form as the request body content:
{
"sessionId": "<session-id>",
"layout": {
"type": "custom",
"stylesheet": "the layout stylesheet (only used with type == custom)",
"screenshareType": "optional layout type to use when there is a screen-sharing stream"
},

"serverUrl": "rtmp://mybarserver/mybarapp",
"streamName": "mybarstream"
}]
},
"resolution": "640x480",
"streamMode" : "auto"
}The JSON object includes the following properties:
sessionId (String) — Set this to the session ID of the OpenTok session you
want to broadcast.
layout (Object) — Optional. Specify this to assign the initial layout type for
the broadcast. This object has three properties: type, stylesheet,
and screenshareType, which are each strings. Valid values for
the layout property are "bestFit"
(best fit), "custom" (custom), "horizontalPresentation"
(horizontal presentation), "pip" (picture-in-picture), and
"verticalPresentation" (vertical presentation)). If you specify a
"custom" layout type, set the stylesheet property of the
layout object to the stylesheet. (For other layout types, do not set a
stylesheet property.) Set the screenshareType property to
the layout type to use when there is a screen-sharing stream in the session.
(This property is optional.) Note if you set the screenshareType property,
you must set the type property to "bestFit" and leave the
stylesheet property unset. If you do not specify an initial layout type,
the broadcast stream uses the Best Fit layout type. For more information, see
Configuring Video Layout for the OpenTok live streaming feature.
multiBroadcastTag (String) — (Optional) Set this to support multiple broadcasts
for the same session simultaneously. Set this to a unique string for each simultaneous broadcast
of an ongoing session. See
Simultaneous broadcasts.
maxDuration (Integer) — Optional. The maximum duration for the broadcast,
in seconds. The broadcast will automatically stop when the maximum duration is reached.
You can set the maximum duration to a value from 60 (60 seconds) to 36000 (10 hours).
The default maximum duration is 4 hours (14,400 seconds).
outputs (Object) — Required. This object defines the types of broadcast
streams you want to start (both HLS and RTMP). You can include HLS, RTMP, or both as broadcast
streams. If you include RTMP streaming, you can specify up to five target RTMP streams (or just
one).
For each RTMP stream, specify serverUrl (the RTMP server URL),
streamName (the stream name, such as the YouTube Live stream name or the
Facebook stream key), and (optionally) id (a unique ID for the stream). If you
specify an ID, it will be included in the REST call response and the REST
method for getting information about a live streaming broadcast. Vonage streams the session
to each RTMP URL you specify. Note that OpenTok live streaming supports RTMP and RTMPS.
For HLS, include a single hls property in the outputs object.
This object includes the following optional properties:
dvr (Boolean) — Whether to enable
DVR functionality
— rewinding, pausing, and resuming — in players that support it
(true), or not (false, the default). With DVR enabled, the HLS URL
will include a ?DVR query string appended to the end.
lowLatency (Boolean) — Whether to enable
low-latency mode
for the HLSstream. Some HLS players do not support low-latency mode. This feature is incompatible
with DVR mode HLS broadcasts.
The HLS URL is returned in the response and in the REST method for getting information about a live streaming broadcast.
resolution (String) — The resolution of the broadcast: either
"640x480" (SD landscape, the default), "1280x720" (HD landscape),
"1920x1080" (FHD landscape), "480x640" (SD portrait),
"720x1280" (HD portrait), or "1080x1920" (FHD portrait). You may want
to use a portrait aspect ratio for broadcasts that include video streams from mobile devices
(which often use the portrait aspect ratio). This property is optional.
streamMode (String) — (Optional) Whether streams included in the broadcast are
selected automatically ("auto", the default) or manually ("manual").
When streams are selected automatically ("auto"), all streams in the session
can be included in the broadcast. When streams are selected manually ("manual"),
you specify which streams to include based on calls to this
REST method. You can specify whether a stream's audio, video, or both are included in
the broadcast. For both automatic and manual modes, the broadcast composer includes streams based on
stream prioritization rules.
If you need to support only one RTMP URL, you can pass in an object (instead of an array of
objects) for the rtmp property value in the POST data you supply when calling
the REST method. For example, the following POST data specifies one RTMP output URL (and does
not include HLS output):
{
"sessionId": "<session-id>",
"layout": {
"type": "custom",
"stylesheet": "the layout stylesheet (only used with type == custom)"
},
"outputs": {
"rtmp": {
"id": "my-id",
"serverUrl": "rtmp://myserver/myapp",
"streamName": "my-stream-name"
}
}

}
}The JSON object includes the following properties:
id — The unique ID for the broadcastsessionId — The OpenTok session IDprojectId — Your OpenTok API keycreatedAt — The time the broadcast started, expressed in milliseconds since
the Unix epoch (January 1, 1970, 00:00:00 UTC)updatedAt — For this start method, this timestamp matches the createdAt
timestamp.resolution — The resolution of the broadcast (either "640x480", "1280x720",
"1920x1080", "480x640", "720x1280", or "1920x1080").status — This is set to "started".
streamMode — Whether all streams are included in the broadcast (`"auto"`)
or you select streams to include in the broadcast (`"manual"`).
streams — An array of objects corresponding to streams currently being
broadcast. This is only set for a broadcast with the status set to "started"
and the streamMode set to "manual". Each
object in the array includes the following properties:
streamId — The stream ID of the stream included in the broadcast.
hasAudio — Whether the stream's audio is included in the broadcast.
hasVideo — Whether the stream's video is included in the broadcast.
maxDuration — The maximum duration for the broadcast (if one was set), in seconds.multiBroadcastTag — The unique tag for simultaneous broadcasts (if one was set).broadcastUrls — An object containing details about the HLS and RTMP
broadcasts.
If you specified an HLS endpoint, the object includes an hls property, which is
set to the URL for the HLS broadcast. Note this HLS broadcast URL points to an index file,
an .M3U8-formatted playlist that contains a list of URLs to .ts media segment files (MPEG-2
transport stream files). While the URLs of both the playlist index file and media segment
files are provided as soon as the HTTP response is returned, these URLs should not
be accessed until 15 – 20 seconds later, after the initiation of the HLS broadcast,
due to the delay between the HLS broadcast and the live streams in the OpenTok session. See
https://developer.apple.com/library/ios/technotes/tn2288/_index.html for more information
about the playlist index file and media segment files for HLS.
If you specified RTMP stream endpoints, the object includes an rtmp property.
This is an array of objects that include information on each of the RTMP streams. Each of
these objects has the following properties: id (the ID you assigned to
the RTMP stream), serverUrl (the server URL), streamName
(the stream name), and status property (which is set to
"connecting"). You can call the OpenTok REST method
to check for status updates for the broadcast.
The HTTP response will have one of the following status codes:

Use this method to stop a live broadcast of an OpenTok session.
Note that a broadcast stops automatically 60 seconds after the last client disconnects from the session. Also there is a default maximum duration of 4 hours (14,400 seconds) for each HLS and RTMP stream (the live stream broadcast automatically stops when this duration is reached). You can change the maximum duration for the broadcast by setting the `maxDuration` property when you [start the broadcast](#start_broadcast) REST method.

### Example
The following example gets details for a specific project:
export token=YOUR_TOKEN_STRING # See "Authentication."
export TB_url=https://api.opentok.com
headerstr="X-OPENTOK-AUTH:$token"
apikey=1234567 # Replace with the project API key.
curl -i\
-X GET \
-H $headerstr \
$TB_url/v2/project/$apikeyThe response is a JSON project details object.
The following example gets details for all of your projects:
export token=YOUR_TOKEN_STRING # See "Authentication."
export TB_url=https://api.opentok.com
headerstr="X-OPENTOK-AUTH:$token"
curl -i\
-X GET \
-H $headerstr \
$TB_url/v2/projectThe response is an array of project details objects.
For security reasons, you may want to generate a new API secret for a project.
Note: Use the new API secret for all REST API calls and with the OpenTok server-side SDKs. When you generate a new API secret, all existing client tokens become invalid (and they cannot be used to connect to OpenTok sessions); use the new API secret with the OpenTok server SDK to generate client tokens.
