Accept

Media types the client can understand

What the Accept header does

The Accept header tells the server which media types the client can handle, so the server can pick a matching representation (content negotiation). Accept: application/json asks for JSON; a browser typically sends a list including text/html. Quality values (;q=0.9) express preference.

Example

Accept: application/json

Where it's used
