First, I wanted to mention that I am a complete novice with Nintex and this project was just handed to me.  So forgive my ignorance as this is a high priority (on my end) task.

I can create custom lists and forms and they work great, but I now need to create a form that uses a POST method that sends to an external link.  I found the Web Request action and have been trying that (and googling til my fingers bled) but not quite sure where to put my <input id> information.  Do those go in the Headers?

Very confused on how to use a Post method using Nintex.

Please help!
