Group APIs
Tencent Cloud Chat SDK supports the following preset group types, each of which pertains to different scenarios.
Work group (Work): Users can join the group only after being invited by group members. This group is similar to ordinary WeChat groups.
Public group (Public): Similar to QQ groups, users can join a public group through requests, which need to be approved by the group owner or group admin.
Meeting group (Meeting): Used together with TRTC to enable scenarios such as video conferencing and online education. Users can join and leave the group freely and view the message history before they join.
Community: Community supports up to 100,000 members and a user can join and leave a community freely without approval. It is suitable for chat scenarios with a super large number of community members, such as knowledge sharing and game discussion. This feature is supported by a client with the SDK edition V5.8 or later. To use it, you need to purchase the premium edition, and then enable it via console > Feature Configuration > Group Configuration > Group Feature Configuration > Community.
Audio-video group (AVChatRoom): An audio-video group allows users to join and leave freely and is suitable for scenarios such as live streaming and chat rooms with on-screen comments. There is no limit on the number of group members.
