# Add Completion Date automatically to your form

In Flokzu you can add the completion date of a form automatically using our Web Service Echo.

In order to do this you must follow the following steps: 

1. Place a Date type field in your form.

2. Add a Service call task before the end event in your process and select Web Service REST. In this example we will call the task 'Add Completion Date to form'.
