Importing Group Messages

Last updated: 2022-06-21 16:13:13


    • This API is used to import group messages without triggering callbacks or sending notifications.
    • When you are migrating your app from another instant messaging system to Tencent Cloud IM, you can use this API to import group message data.

    API Calling Description

    Applicable group types

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

    Above are the built-in group types of IM. For more information, see Group System.


    Audio-video groups (AVChatRoom) do not support importing group messages. If you attempt to import group messages for an audio-video group, error 10007 will be returned. Therefore, members of an audio-video group cannot view the messages sent before they join the group.

    Maximum call frequency

    200 calls per second

    Sample request

    A single request can import up to seven group messages.
    After messages are imported through this API, the unread message count for all members will become 0. To retain the unread message count, you need to import group members or set the unread message count for members after importing all messages.
    The messages must be imported in ascending order by timestamp, and the timestamps of imported messages must be earlier than the current time, and later than the group creation time and the creation time of the latest message in the group. Otherwise, the import will fail.
