Getting a 415 code error - what's the fix? or Why am I seeing a 415 code and how do I resolve it?[/b

Had this exact 415 code problem last month. My fix? The server was picky about the order of headers. Content-Type *had* to be the first header.

Postman lets you reorder headers—give that a shot. Also, try removing other headers temporarily to isolate the issue.
