Thanks for the sharing of the article and your knowledge too.

What I am trying to do is the following:

I have a record producer which has some fields. When the user enters a value on "ID" field, then a catalog client script sends the "ID" field value (let's say 123456789) to the script include. Within my script include I make a post call to the third system through a mid server and I am waiting for a response. Then this response is sent back to the catalog client script and auto-populates some other form fields.

Does the execute() method seems logical to my case?

Thank you so much for your patience and all the knowledge that you keep sharing with me.
