So I'm having a problem getting the POST operation (Below - # Start execution) to work. Everything, I have tried has resulted in a 400 error. I have also tried setting the post variable just using a string and the JSON ({"parameters":....}). If anyone can give me a some help figuring out what I'm doing wrong here it would be appreciated.
