Importing Group Messages

Feature Overview

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 Chat, you can use this API to import group message data.

API Calling Description

Applicable group types

Note
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.

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.
