Setting the Unread Message Count of a Member

Last updated: 2022-04-06 14:47:54

    This document is only for users who are migrating their apps to Tencent Cloud IM.

    Feature Description

    • This API is used by app admins to set the unread message count of a group member. When this API is called, no callback is triggered and no notification is sent.
    • When you are migrating your app from another IM system to Tencent Cloud IM, you can use this API to set the unread message count of group members.

    API Call Description

    Applicable group types

    Group Type ID RESTful API Support
    Private Yes. Same as work group (Work) in the new version.
    Public Yes.
    ChatRoom No. Same as meeting group (Meeting) in the new version.
    AVChatRoom No.
    Community Yes.

    These are the built-in group types in IM. For detailed information, see Group System.


    ChatRoom and AVChatroom (audio-video) groups do not support unread message counts. Therefore, you cannot set an unread message count for members of these two group types. If you try to do so, no error will be returned.
