A group can be used for multiple users to communicate with each other on a particular topic or interest.
GUID
- Each group is uniquely identified using a GUID.
- The GUID is typically the primary ID of the group from your database. If you do not store group information in your database, you can generate a random string for use as GUID.
GUID can be alphanumeric with underscore and hyphen. Spaces, punctuation and other special characters are not allowed.
Group Types
CometChat supports three different types of groups:
| Type | Visibility | Participation |
|---|
| Public | All users | Any user can choose to join |
| Password | All users | Any user with a valid password can join |
| Private | Only members | Invited users are auto-joined |
Member Scopes
Once a participant joins a group, they become a member. Members remain part of the group indefinitely — to stop receiving messages, calls, and notifications, a member must be kicked, banned, or leave the group.
| Scope | Default | Privileges |
|---|
| Admin | Group creator | Manage all members, add members, kick & ban anyone, send & receive messages & calls, update & delete group |
| Moderator | — | Change scope of participants, kick & ban participants, update group, send & receive messages & calls |
| Participant | All other members | Send & receive messages & calls |
