Custom Notification using Apex in Salesforce

In the below example Notification will be sent to the Account owner when the file is attached to their Account records.
 
Notification Type in Setup:
 
 
Sample Code:
trigger ContentDocumentLinkTrigger on ContentDocumentLink ( after insert ) {
    
       
    Set < Id > setAccIds = new Set < Id >();
    Map < Id, Id > mapAccIdContDocId = new Map < Id, Id >();
       
    for ( ContentDocumentLink objCDL : trigger.new ) {
       
        String strEntityId = objCDL.LinkedEntityId;
        
        if ( String.isNotBlank( objCDL.LinkedEntityId ) && strEntityId.left( 3 ) == '001' ) {
       
            setAccIds.add( objCDL.LinkedEntityId );
            mapAccIdContDocId.put( objCDL.LinkedEntityId, objCDL.ContentDocumentId );
           
        }
        
    }
    
    if ( setAccIds.size() > 0 ) {
    
        CustomNotificationType notificationType = [SELECT Id FROM CustomNotificationType WHERE DeveloperName = 'Desktop'];
                   
        Messaging.CustomNotification notification = new Messaging.CustomNotification();
        Set < String > recipientsIds = new Set < String >();
        notification.setTitle( 'File Attached to your Account' );
        notification.setNotificationTypeId( notificationType.Id );
    
        for ( Account objAcc : [ SELECT Id, OwnerId FROM Account WHERE Id IN: setAccIds ] ) {
       
            notification.setBody( 'File Id is ' + mapAccIdContDocId.get( objAcc.Id ) );
            notification.setTargetId( objAcc.Id );
            recipientsIds.add( objAcc.OwnerId );
            notification.send( recipientsIds );
       
        }
    
    }

}
 
Output:


send() is not bulkified. So, remember 150 DML Governor limit.
