SALESFORCE HOW TO CREATE CHATTER GROUPS IN APEX ?

Creating Chatter Groups in Apex

• To create chatter groups in Salesforce dynamically we will create a chatter group first and then we'll add group members into it.
• So let's get started by creating chatter group first.

=============================================
 CollaborationGroup myGroup = new CollaborationGroup();

 myGroup.Name='My Group'; // Define group name here

 myGroup.CollaborationType='Public'; //It can be 'Public' or 'Private'                   
 insert myGroup; 

=============================================

• Now let,s add chatter group members into it.

=============================================

CollaborationGroupMember groupMember = new CollaborationGroupMember();

 groupMember.memberid = 'userId'; //Provide userId here

 groupMember.CollaborationGroupId = myGroup.Id; //Id of group created above

 insert groupMember;

=============================================

• Now let's combine and create group with group member.

=============================================

 public class ApexGroup {

   public static void group(){

 CollaborationGroup myGroup = new CollaborationGroup();

 myGroup.Name='My Group'; // Define group name here

 myGroup.CollaborationType='Public'; //It can be 'Public' or 'Private'  
insert myGroup;

        

CollaborationGroupMember groupMember = new CollaborationGroupMember();

groupMember.memberid = 'userId'; //Provide userId here

groupMember.CollaborationGroupId = myGroup.Id; //Id of group created above

insert groupMember;

   }

} 

=============================================

NOTE:

• In case of a community or portal user you cannot access external user Id and create group between a portal user and internal user by using apex otherwise, you will get "insufficient access rights on cross-reference id" error.
