Pipeline to remove file attachments

That's odd. I'm just not getting that result.  Unless I'm doing something wrong here.  When I run this in my Pipeline using the 'Make Request' step (in a for loop for all attachments), it shows the attachment is gone in form and report view:

https://<my_realm>.quickbase.com/db/<my_db_id>?act=API_EditRecord&rid={{a.id}}&_fid_113=&delfile_fid_113=1

But when I go to 'App Management > Manage File Attachments' in QB, the attachment space remains the same and shows that all the attachments are still there.

Ah, I see what I did.  I set to the HTTP method to GET and not POST.  I also needed to set the number of versions to retain for each attachment field to 1. My bad.  What MarkShnier__You and PrashantMaheshw mentioned is correct.
