Groups

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
