Channel Management REST API

In addition to the Voice/Video SDK integrated into the app client, Agora provides RESTful APIs for channel management, with which you can manage users in the channel and query channel statistics at the app server.

This page provides detailed help for the Agora Channel Management RESTful APIs.

Basic information

This section provides basic information about the Agora Channel Management RESTful APIs.

Domain

All requests are sent to the domain name: api.agora.io. See Ensure service reliability for alternate domain names.

Data format

The Content-Type field in all HTTP request headers is application/json. All requests and responses are in JSON format. All request URLs and request bodies are case-sensitive.

Authentication

The Agora Channel Management RESTful APIs only support HTTPS. Before sending HTTP requests, you must generate a Base64-encoded credential with the Customer ID and Customer Secret provided by Agora, and pass the credential to the Authorization field in the HTTP request header. See HTTP authentication.

Call frequency limit

For each Agora account (not each App ID), the call frequency of each online channel statistics query API is no more than 20 queries per second, and the call frequency of each other API is no more than 10 queries per second. If you are frequency limited when calling the APIs, please see How can I avoid being frequency limited when calling Agora Server RESTful APIs to optimize API call frequency.

Banning user privileges

To maximize the success of core APIs such as POST, PUT, and DELETE, the success rate and accuracy of the GET method may be compromised, especially when the network connection is poor due to abnormal fluctuations. In the response of the GET method, some request parameters may be missing.

Note

When calling POST to create a rule (time is not set to 0), that you need to update or delete later, we recommend the following operations:

Save the rule ID returned in the POST request on your server, and rely on this ID for subsequent update and delete operations.
To ensure that you can still obtain the rule ID returned in POST during poor network connections, set the timeout for the POST request to 20 seconds or higher. Make sure that the timeout is set to no less than 5 seconds.
In case the POST request times out or returns a 504 error, use the response of the GET method to obtain the rule ID. If the rule exists, it indicates that the POST request is successful, and you can save the rule ID on your server.

Creates a rule

Creates a rule of banning specified user privileges.

The user privileges (privileges) that can be banned include the following:

join_channel: Joining a channel.
publish_audio: Publishing audio.
publish_video: Publishing video.

The banning rule works based on the following three fields: cname, uid, and ip.

When you set privileges as join_channel, the rule works as follows:

If you set ip, but not cname or uid, then all users with this ip cannot join any channel in the app.

Using ip as a filter field may incorrectly block users who should not be blocked, for example, in a scenario where multiple users share an IP address.
If you set cname, but not uid or ip, then no one can join the channel specified by the cname field.

Using cname as a filter field directly blocks the channel with the cname.
If you set uid, but not cname or ip, then the user with the user ID cannot join any channel in the app.
If you set cname and uid, but not ip, then the user with the user ID cannot join the channel specified by the cname field.

When you set privileges as publish_audio or publish_video, the rule works as follows:

If you set ip, but not cname or uid, then the users with this ip cannot publish audio or video in any channel of the app.
If you set cname, but not uid or ip, then no one can publish audio or video in the channel specified bythe cname field.
If you set uid, but not cname or ip, then the user with the user ID cannot publish audio or video inany channel of the app.
If you set cname and uid, but not ip, then the user with the user ID cannot publish audio or video inthe channel specified by the cname field.

A user who is kicked out of a channel (that is when you set privileges as join_channel) receives one of the following callbacks based on their platform:

Android: The onConnectionStateChanged callback reports CONNECTION_CHANGED_BANNED_BY_SERVER(3).
iOS/macOS: The connectionChangedToState callback reports AgoraConnectionChangedBannedByServer(3).
Web (3.x): The Client.on("client-banned") callback.
Web (4.x): The Client.on("connection-state-change") callback.
Windows:The onConnectionStateChanged callback reports CONNECTION_CHANGED_BANNED_BY_SERVER(3).
Electron: The AgoraRtcEngine.on("connectionStateChanged") callback reports 3.
Unity: The OnConnectionStateChangedHandler callback reports CONNECTION_CHANGED_BANNED_BY_SERVER(3).
React Native: The ConnectionStateChanged callback reports BannedByServer(3).
Flutter: The ConnectionStateChanged callback reports BannedByServer(3).

Request parameters

Request body parameters

Pass in the following parameters in the request body:

Parameter	Data type	Required/Optional	Description
`appid`	String	Required	The App ID of the project. You can get it through one of the following methods: Copy from the Agora Console Call the Get all projects API, and read the value of the `vendor_key` field in the response body.
`cname`	String	Optional	The channel name.
`uid`	Number	Optional	The user ID. Do not set it as `0`.
`ip`	String	Optional	The IP address of the user. Do not set it as `0`.
`time`	Number	Required	The time duration (in minutes) to ban the user. The value range is [1,1440]. Note If the set value is between `0` and `1`, Agora automatically sets the value to `1`. If the set value is greater than `1440`, Agora automatically sets the value to `1440`. If the set value is `0`, the banning rule does not take effect. The server sets all users that conform to the rule offline, and users can log in again to rejoin the channel. Use either `time` or `time_in_seconds`. If you set both parameters, the `time_in_seconds` parameter takes effect; if you set neither of these parameters, the Agora server automatically sets the banning time duration to 60 minutes, that is, 3600 seconds.
`time_in_seconds`	Number	Required	The time duration (in seconds) to ban the user. The value range is [10,86430]. Note If the set value is between `0` and `10`, Agora automatically sets the value to `10`. If the set value is greater than `86430`, Agora automatically sets the value to `86430`. If the set value is `0`, the banning rule does not take effect. The server sets all users that conform to the rule offline, and users can log in again to rejoin the channel. Use either `time` or `time_in_seconds`. If you set both parameters, the `time_in_seconds` parameter takes effect; if you set neither of these parameters, the Agora server automatically sets the banning time duration to 60 minutes, that is, 3600 seconds.
`privileges`	Array	Required	The user privileges you want to block. You can choose the following values: `join_channel`: String. Bans a user from joining a channel or kicks a user out of a channel. `publish_audio`: String. Bans a user from publishing audio. You can pass in both `publish_audio` and `publish_video` to ban a user from publishing audio and video. `publish_video`: Bans a user from publishing video. You can pass in both `publish_audio` and `publish_video` to ban a user from publishing audio and video.

}

Gets the user list

Gets the list of all users in a specified channel.

The return list differs with the channel profile as follows:

In COMMUNICATION profile, this API returns the list of all users in the channel.
In LIVE_BROADCASTING profile, this API returns the list of all hosts and audience members in the channel.

Users in a channel must use the same channel profile; otherwise, the query results may be inaccurate.
You can synchronize the online channel statistics either by calling this API or by calling the Gets the user status API. Compared with the Gets the user status API, this API requires a lower call frequency and has a higher query efficiency. Therefore, Agora recommends using this API to query online channel statistics.

This API gets the channel list by page. In the request URL, you can specify the page number and the number of channels shown on the page. A successful request returns the channel list of the specified page according to the set page_size.

If the number of users in a channel changes frequently, the query results may be inaccurate. The following situations may occur:

A channel appears repeatedly in different pages.
A channel does not appear in any page.

Ensure service reliability

This section presents the overall strategy you use to ensure high availability of REST services.

Switch the domain name

To ensure high availability of REST services, Agora enables you to switch domain names when you experience service outage due to regional network failures. Take the following steps to set up and switch your domain name:

Set the primary domain name based on the location of your service server:
- If the DNS address of the service server is located in a country or region other than mainland China, set the primary domain name to api.agora.io.
- If the DNS address of the service server is in mainland China, set the primary domain name to api.sd-rtn.com.
If your attempt to initiate a RESTful API request using the primary domain fails, set up your retry strategy as follows:
1. Primary domain retry: Retry using the same primary domain name.
2. Alternate domain retry:
  - If the current primary domain name is api.sd-rtn.com, use api.agora.io as the alternate domain name.
  - If the current primary domain name is api.agora.io, use api.sd-rtn.com as the alternate domain name.
3. Adjacent domain retry: If alternate domain retry fails, retry using the domain name adjacent to the current region.
  
  For example, suppose your business server is located in Europe. You set the primary domain name to api.agora.io, and the business server resolves the primary domain name to Germany. Germany is located in central Europe (api-eu-central-1.agora.io). The domain name table shows that the adjacent area is West Europe. Use the api-eu-west-1.agora.io or api-eu-west-1.sd-rtn.com domain name to retry.

Precautions

Take the following precautions when setting up your retry strategy:

To avoid exceeding the QPS limit with retry requests, best practice is to use a back-off strategy. For example, wait 1 second before you retry for the first time, wait 3 seconds before retrying the second time, and wait 6 seconds before retry a third time.
If the request fails because of a network problem rather than a DNS domain name resolution problem, skip alternate domain retry and proceed to adjacent domain retry.
Before switching to the region domain name, ensure that the REST services you wish to use, for example, cloud recording or channel management, are deployed in that region.

Domain name table

The following table shows the primary and region domain names for various regions.

Primary domain name	Region domain name	Region
