415 Unsupported Media Type

Hi All

We are doing an SOAP to REST Sync Interface.

We have tested the integration using SOAPUI & PostMan and the response token for our request OAuth is successful. But when trying in real time, we are getting 415:Unsupported Media type error in REST CC.rest-cc-error.png

But the strange part here is, the same payload works in SOAPUI but not in real time. We tried with Transform Bean for Content-Type as well but no improvement on response.

We have used Query String and URLEncoded.
