SOAP XML REQUEST AND REPONSE IN POSTMAN

Whenever you need to verify the request and response structures of a SOAP XML API using Postman. Any mistake or barrier you encounter could cause your work to cease. Similarly, I got an error saying that

The server cannot service the request because the media type is unsupported

To easily fix this problem Add just one Header Key: Content-Type Value: text/xml in the headers section of postman.

And that's it!
