let the client and server agree on a format.

The client says what it can read with Accept. The server says what it sent with Content-Type.
Accept: application/json asks for JSON. Accept: application/xml asks for XML.
If the server cannot produce the requested type, it answers 406 Not Acceptable.
If the client sends a body type the server cannot read, the answer is 415 Unsupported Media Type.
In Spring, produces and consumes on a mapping declare what an endpoint supports.
