Based on this thread. I have form that is generated by the contents of several data extensions. The contents in these are meant to be editable, so the form can be changed without diving into the actual code at all. The handler needs to receive the contents of the form, but I can't get Platform.Request.GetPostData() parse into a json object. Using the code from the previous thread, I just get a raw post string and nothing else.
How do I use AMPScript or SSJS to convert raw post data into either an array or json?
EDIT: To clarify, I'm trying to get key-value pairs.
