Auto-Assign Case Owners by Origin in Salesforce using Apex

Business Requirement

Assign Case ownership based on the Origin:

• Phone → Assign to Phone Support Agent (User ID: 005XXXXXXXXXXXX)
• Email → Assign to Email Support Agent (User ID: 005YYYYYYYYYYYY)
• Web → Assign to Web Support Agent (User ID: 005ZZZZZZZZZZZZ)

Apex Class

This Apex class handles the owner assignment logic based on the case’s Origin:

public class CaseOwnerAssigner {
    public static void assignCaseOwner(Id caseId) {
        Case c = [SELECT Id, Origin, OwnerId FROM Case WHERE Id = :caseId];

        String phoneAgentId = '005XXXXXXXXXXXX';
        String emailAgentId = '005YYYYYYYYYYYY';
        String webAgentId   = '005ZZZZZZZZZZZZ';

        if (c.Origin == 'Phone') {
            c.OwnerId = phoneAgentId;
        } else if (c.Origin == 'Email') {
            c.OwnerId = emailAgentId;
        } else if (c.Origin == 'Web') {
            c.OwnerId = webAgentId;
        }

        update c;
    }
}

How It Works

• Query the Case record using the provided ID.
• Check the Origin field value.
• Assign the corresponding OwnerId (User or Queue).
• Update the Case record.
