Chat

Group Management

Based on common use cases, Chat provides the following default group types: work group (Work), public group (Public), meeting group (Meeting), audio-video group (AVChatRoom), and Community group (Community). For more information, see Group Types.
You can perform the following operations on groups:
Group Operation
Description
Remarks
Create a group
This operation creates a new group. You can specify the group type, name, and a list of users to add to the group. After the group is created, the group ID is returned, which is the unique identifier of the group and can be used to perform other group operations such as message sending and receiving.
The daily limit of net group consumption is 10,000 per app.
Transfer a group
This operation transfers a group and changes the group owner to another user.
The app admin can transfer a group through the RESTful API. The only other role that can transfer a group is the group owner.
Disband a group
This operation disbands a group that has been created on the app. When the group is disbanded, all group members receive a system message stating that the group has been disbanded.
The app admin can call the RESTful API to disband any group. The permission to disband a group on an app varies depending on the member role:
For a public group (Public), meeting group (Meeting), audio-video group (AVChatRoom), or community group (Community), only the group owner can disband the group.
For a work group (Work), no one in the group can disband the group.
Caution
When you create a group, Chat assigns a default group ID that begins with @TGS#. You can also manually specify a group ID. For more information, see Custom Group IDs.
After the group is created, a system message about the group creation is sent to the group owner‘s device to ensure synchronization across multiple devices (once a group is created on one device, all devices instantly perceive the created group).

Group Profile Management

The group profile includes properties that are specific to a single group, such as the group name, introduction, announcement, and group owner, as well as custom group fields.

Group members obtain the group profile: Group members can obtain the group profile.Non-members obtain the group profile: Non-members can only obtain the group profile if it is made public.Obtain the personal profile in the group: users can obtain their own profiles in all groups, or in a single group.Obtain the profile of a group member: An audio-video group (AVChatRoom) does not store group member information and does not support obtaining the profile of a group member.
Modify the group profile
You can modify the group name, introduction, announcement, profile photo, group name card, membership request options, group-level custom fields, in-group roles of members, member-level custom fields, and group message receiving options.
Currently, you can configure callbacks for group name, introduction, announcement, and profile photo URL changes for the app in the console. To enable callbacks for changes in other group information, including group-level custom fields, please submit a ticket.

Group Member/Group Management

Group member management involves two aspects:
Obtain and modify user profile in the group. This information can be obtained and set only by users themselves, for example, message receiving options.
Obtain and modify other group members’ information, including the role, joining time, time of last message, group name card, and member-level custom information.

Community groups does not require approval to join the group directly by default. If approval is required to join the group, it can be controlled through the ApplyJoinOption field in the group information.
For other built-in group types, the result of the membership application depends on the ApplyJoinOption field in the group profile.
