Item updated event receiver not firing when workflow updates the list item

Question

I have an event receiver on an item updated event, when i manually update the list item, the event receiver is firing and calling the method, but when i update the list item through workflow step,when workflow is approved, it does not fire. i am deploying the solution as a farm solution.

public class CreateZohoTicket : SPItemEventReceiver    {
        /// <summary>
        /// An item was updated.
        /// </summary>
        public override void ItemUpdated(SPItemEventProperties properties)
        {  
            base.ItemUpdated(properties);

            if ((string)properties.AfterProperties["Status"] == "Approved")
            {               

                CreateTicket(properties);

                //calling a web service POST method in CreateTicket
            }          

        }

Answer 1

If you are using Set Field in current item action in your SharePoint designer workflow to update a list item, it will not trigger item updated or any other event receiver in list.

You will have to use Update list item action in your designer workflow, so when workflow updates your list item, item updated event receiver will be triggered.

Hope this will help you!
