What is Content-Type?

Content-Type (also called MIME type, Media type): An HTTP header naming the media type of the body being sent, such as application/json, text/html or multipart/form-data, so the receiver knows how to read it. Sending JSON with the wrong value is a frequent cause of rejected requests.
