Introduction to REST API

The RESTful API is a part of the TRTC Call's backend HTTP Hub Management Interface Hub, providing developers with a simplified management entry. For the RESTful APIs currently supported by the TRTC Call, please refer to REST API List.
For security reasons, the RESTful API is only available via HTTPS Interface.

Use Conditions

The REST API is currently in beta. During the beta period, applications (SDKAppId) that have enabled the Group Call Version of TRTC Call can use the REST API. You can also activate a free trial of the experience version. For version descriptions and activation guidelines, refer to Activate the Service.
Currently, the RESTful API is available only in specific versions of TUICallKit across different platforms, as detailed in the table below:
Platform/Framework
Version number
Android/iOS/Flutter/uni-app (client)
≥ 1.7.1
Web
≥ 1.4.6
WeChat Mini Program
≥ 1.5.1
Note:
Only after all participating platforms/frameworks are upgraded to the versions mentioned above, can the corresponding call information be peeked at in the console.
During the Beta Testing Period, the RESTful API supports querying data from the past 7 days.

Calling method

Request URL

The URL format of the RESTful API is as follows:
https://xxxxxx/$version/$kind/$command?sdkappid=$SDKAppID&identifier=$identifier&usersig=$usersig&random=99999999&contenttype=json
The meanings and values of each parameter are as follows (both parameter names and their values are case-sensitive):
Parameter
Meaning
Fetching Value
https
Request protocol
The request protocol is HTTPS, and the request method is POST
xxxxxx
reserved domain name
callkit-intl.trtc.tencent-cloud.com
version
Protocol Version Number
Fixed as v1
kind
Management Classification
Example:
v1/records/get_record_by_callId, where `records` is a kind
command
The word `command`, combined with `kind`, is used to indicate a specific business feature
Example: v1/records/get_record_by_callId, where `get_record_by_callId` is a command
sdkappid
The application identifier accessed in the console
Obtained when applying for integration
identifier
username, must be an App Administrator Account when calling RESTful APIs
Using the Admin account of Chat
usersig
password corresponding to username
Refer to Generating UserSig
random
Identifies the random number parameter for the current request
32-bit unsigned integer random number, ranging from 0 to 4294967295
contenttype
Request Format
Fixed value: json
Note:
After obtaining or purchasing package bundles, an administrator account named `administrator` will be created in the Chat account system. Please use `administrator` for the identifier parameter in requests. If you cancel or delete an administrator in Chat Account Management, please correctly specify the administrator account and corresponding UserSig.
Apps can either generate a UserSig for the administrator account at every RESTful API call, or generate a fixed UserSig for repeated use. However, it is crucial to pay attention to the UserSig's validity period.
During operations such as creating or entering a room, the system will automatically import Chat accounts into the Chat System. Please be aware.

HTTP Request Body Format

The RESTful API only supports the POST method, and its request body is in JSON format. For specific body formats, refer to the detailed description of each API.
Note:
The POST body cannot be empty. Even if a protocol does not require any information to be carried, it must still include an empty JSON object, namely {}.

HTTP return code

Unless a network error occurs (e.g., 502 error), the call result of the RESTful API is always 200. The actual error code and error message of the API call are returned in the HTTP response body.

HTTP Response Body Format

The response body of the RESTful API is also in JSON format, and its format conforms to the following characteristics:
{
    "errorCode": 0, 
    "errorMessage": "Success",
    "requestId": "1c8960ac38d61be38b6fb219db0182d1", 
    "data": {} 
}
The response body must contain three attributes: errorCode, errorMessage, requestId. Their meanings are as follows:
Field
Type
Description
errorCode
String
Error code, 0 for success, others for failure
errorMessage
String
Error message
requestId
Integer
Request Unique Identifier

FAQs

Is there a chance that REST API requests timeout, receiving no response?

You can confirm from the following aspects:
1. The backend REST interface's timeout setting is 3s, the caller's timeout setting should be longer than 3s.
2. telnet callkit-intl.trtc.tencent-cloud.com 443 to confirm if the service port can be connected.
3. Use curl -I https://callkit-intl.trtc.tencent-cloud.com for a simple test to see if the status code is 200.
4. Confirm whether the machine's DNS server configuration is an internal DNS server or a public DNS server. If it is an internal DNS server, ensure that the DNS server's network egress and the region ISP of the machine's network egress IP match.
5. It is recommended for business callers to use the long connection + connection pool pattern.
