Manage chat group block list

A chat group block list refers to a list of users that can neither see nor receive group messages. Chat provides a complete set of block list management methods, including adding and removing chat group members from the chat group block list, and retrieving the block list.

This page shows how to manage a chat group block list by calling the Chat RESTful APIs. Before calling the following methods, ensure that you understand the call frequency limit described in Limitations.

Common parameters​

The following table lists common request and response parameters of the Chat RESTful APIs:

Request parameters ​

ParameterTypeDescriptionRequired
hostStringThe domain name assigned by the Chat service to access RESTful APIs. For how to get the domain name, see Get the information of your project.Yes
org_nameStringThe unique identifier assigned to each company (organization) by the Chat service. For how to get the org name, see Get the information of your project.Yes
app_nameStringThe unique identifier assigned to each app by the Chat service. For how to get the app name, see Get the information of your project.Yes
usernameStringThe unique login account of the user. The user ID must be 64 characters or less and cannot be empty. The following character sets are supported:
  • 26 lowercase English letters (a-z)
  • 26 uppercase English letters (A-Z)
  • 10 numbers (0-9)
  • "_", "-", "."
  • The username is case insensitive, so Aa and aa are the same username.
  • Ensure that each username under the same app is unique.
Yes

Response parameters ​

ParameterTypeDescription
actionStringThe request method.
organizationStringThe unique identifier assigned to each company (organization) by the Chat service. This is the same as org_name.
applicationStringA unique internal ID assigned to each app by the Chat service. You can safely ignore this parameter.
applicationNameStringThe unique identifier assigned to each app by the Chat service. This is the same as app_name.
uriStringThe request URI.
pathStringThe request path, which is part of the request URI. You can safely ignore this parameter.
entities JSONThe response entity.
dataJSONThe details of the response.
timestampNumberThe Unix timestamp (ms) of the HTTP response.
durationNumberThe duration (ms) from when the HTTP request is sent to the time the response is received.

Authorization​

Chat RESTful APIs require Bearer HTTP authentication. Every time an HTTP request is sent, the following Authorization field must be filled in the request header:


_1
Authorization: Bearer ${YourAppToken}

In order to improve the security of the project, Agora uses a token (dynamic key) to authenticate users before they log in to the chat system. Chat RESTful APIs only support authenticating users using app tokens. For details, see Authentication using App Token.

Retrieving the chat group block list​

Retrieves the block list of the specified chat group. Users added to the block list can neither see nor receive messages in the chat group.

For each App Key, the call frequency limit of this method is 100 per second.

HTTP request​


_1
GET https://{host}/{org_name}/{app_name}/chatgroups/{group_id}/blocks/users?pageSize={N}&cursor={cursor}

Path parameter​

ParameterTypeDescriptionRequired
group_idStringThe group ID.Yes

For other parameters and detailed descriptions, see Common parameters.

Query parameter​

ParameterTypeDescriptionRequired
pageSizeNumberThe number of users on the block list to retrieve per page.Yes
cursorStringThe position from which to start getting data.Yes
If you pass in neither pageSize nor cursor, the server returns the top 500 users in the descending order of time when they are added to the block list. If you pass in only pageSize, but not cursor, the server returns a maximum of 50 users in the descending order of time when they are added to the block list.

Request header​

ParameterTypeDescriptionRequired
Content-TypeStringThe parameter type. Set it as application/json.Yes
AuthorizationStringThe authentication token of the user or administrator, in the format of Bearer ${token}, where Bearer is a fixed character, followed by an English space, and then the obtained token value.Yes

HTTP response​

Response body​

If the returned HTTP status code is 200, the request succeeds, and the data field in the response body contains the usernames in the group block list.

If the returned HTTP status code is not 200, the request fails. You can refer to Status code for possible causes.

Example​

Request example​


_1
curl -X GET -H 'Accept: application/json' -H 'Authorization: Bearer <YourAppToken>' 'https://XXXX/XXXX/XXXX/chatgroups/66XXXX85/blocks/users?pageSize=2'
