mesman

I'm using Postman to upload an XML file to a site that transforms the file. I tried to structure the WAPT POST request to match the Postman POST request, but I'm really struggling with it. The request in Postman is attached in P1.jpg and P2.jpg -- my attempt to move that to WAPT is in P3.jpg. Any insights would be very much appreciated. I've been banging my head against the wall on this one for too long.
