RESTful 인터페이스 개요
RESTful APIs are HTTP management APIs that provide the app backend with a management entry. For more information about RESTful APIs that Chat supports, see RESTful API List.
In addition to RESTful APIs, the app console also supports simple data management and one-to-one/group messaging. Developers can manage, check, and test data in the console. Even though RESTful APIs are less user-friendly, they provide powerful management capabilities.
For security concerns, RESTful APIs are supported over HTTPS only.
Prerequisites
Before you call a RESTful API, complete the following operations:
1. Create an app in the Chat console. For more information, see Creating and Upgrading an Application.
2. Assign an admin account to the app. For more information, see the Configuring Account Admins section in Basic Configuration.
Caution
To avoid unnecessary call errors, use the admin account to call a RESTful API.
Calling Method
Request URL
The URL format of a RESTful API is as follows:
https://xxxxxx/$ver/$servicename/$command?sdkappid=$SDKAppID&identifier=$identifier&usersig=$usersig&random=99999999&contenttype=json
The descriptions and values of parameters are as follows (parameter names and parameter values are case-sensitive):
Parameter | Description | Value |
https | Request protocol | The request protocol is HTTPS, and the request method is POST. |
xxxxxx | Dedicated domain name | China: console.tim.qq.com (backup: adminapi.my-imcloud.com) Singapore: adminapisgp.im.qcloud.com (backup: adminapisgp.my-imcloud.com) Seoul:adminapikr.im.qcloud.com (backup: adminapikr.my-imcloud.com) Frankfurt: adminapiger.im.qcloud.com (backup: adminapiger.my-imcloud.com) Silicon Valley: adminapiusa.im.qcloud.com (backup: adminapiusa.my-imcloud.com) Jakarta: adminapiidn.im.qcloud.com (backup: adminapiidn.my-imcloud.com) |
ver | Protocol version number | Always v4 . |
servicename | Internal service name. Different values of servicename correspond to different service types. | Example:For v4/im_open_login_svc/account_import , im_open_login_svc is the servicename .For more information, see RESTful API List. |
command | Command word. This parameter is used with the servicename parameter to identify a specific service feature. | Example:For v4/im_open_login_svc/account_import , account_import is the command .For more information, see RESTful API List. |
sdkappid | App ID obtained in the Chat console | You can obtain the SDKAppID when applying for Chat SDK access. |
identifier | Username, which must be the app admin account when a RESTful API is called | |
usersig | Password that corresponds to the user name. | |
random | A parameter used to identify the current request | A random 32-bit unsigned integer ranging from 0 to 4,294,967,295 |
contenttype | Request format | Always json . |
Note
When the app server calls a RESTful API,
identifier
must be the app admin account.The app can generate a
UserSig
for the admin account each time it calls a RESTful API or generate a fixed UserSig
for reuse with period of validity.HTTP request body format
RESTful APIs only support the POST method, and its request body is in JSON format. For more information about the request body format, see the detailed description of each API.
Note that POST request bodies cannot be empty. Even when no information is required in a request body, the request body still needs to carry an empty JSON object (
{}
).HTTP return code
The returned HTTP status code for RESTful APIs is always 200 unless a network error (such as error 502) occurs. The specific error code and error message are included in the HTTP response body.
HTTP response body format
The RESTful API response body is in the JSON format and has the following elements:
{"ActionStatus": "OK","ErrorInfo": "","ErrorCode": 0// Other RESTful API response content}
The response body must contain the
ActionStatus
, ErrorInfo
, and ErrorCode
fields. These three fields are described as follows:Field | Type | Description |
ActionStatus | String | Request result. OK : Successful. FAIL : Failed. If the request fails, the cause of failure is displayed in the ErrorInfo field. |
ErrorInfo | String | Failure causes |
ErrorCode | Integer |

RESTful API Common Error Codes
Error Code | Description |
60002 | HTTP parsing error. Check the URL format of the HTTP request. |
60003 | JSON parsing error. Check the JSON format of the HTTP request. |
60004 | Account or signature error in the request URL or JSON request body. |
60005 | Account or signature error in the request URL or JSON request body. |
60006 | Invalid SDKAppID. Check the validity of SDKAppID. |

60010 | The request requires app admin permissions. |

FAQs
The RESTful API request timed out and no response was received.
1. The timeout period specified for the RESTful API in the Chat backend is three seconds. You need to specify a timeout period that is longer than three seconds.
2. Run
telnet console.tim.qq.com 443
to check whether the service port is accessible.3. Run
curl -I https://console.tim.qq.com
to check whether the status code is 200.4. Check whether the machine uses a private or public DNS server. If the machine uses a private DNS server, make sure that the DNS server egress is in the same region as the ISP to which the egress IP of the machine belongs.
5. You are advised to use the "persistent connection+connection pool" mode.
Note
It is recommended that you use a RESTful API persistent connection to connect to the SDK. The reason is that it takes a long time to establish HTTPS non-persistent connections because each request causes TCP+TLS handshake overhead.
For scenario where a standard HTTP library is used: for HTTP 1.0, the request header
Connection: keep-alive
needs to be specified; for HTTP 1.1, persistent connections are supported by default; for scenarios where HTTPS requests are encapsulated based on TCP, TCP connections can be reused to send and receive requests.
