Authentication request works in x-www-form-urlencoded but not raw

I am trying to authenticate using the raw content format type using the same credentials that I am entering in for my POST request via the x-www-form-urlencoded but I keep receiving a 415 Unsupported Media Type response. Does anyone know what I might be missing in this request?

I can’t post the actual credentials for security sake but I am using the same HTTP URL, it is a POST request, I have tried switching the content type to all of the choices (text, json, xml, javascript etc.) with no luck.

I am more curious if I am not adding something into my raw request that is inherently added via the ‘x-www.form-urlencoded’ content format type? Or if there is something else I am clearly missing.

Thanks

When you are sending “RAW” data type, are you selecting the appropriate Content-Type?
You are able to set it via a drop down.
