Manage group members

Group member management involves operations such as member creation and deletion. Chat provides multiple APIs for adding and retrieving group members, adding a group administrator, and transferring the group owner.

This page shows how to manage group members 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:

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

  • 26 lowercase English letters (a-z)
  • 26 uppercase English letters (A-Z)
  • 10 numbers (0-9)
