The headers contain additional information about every request that we send to the server. The headers that you will use more frequently during development are these:
- Content-Type: To tell the server which type of response you are waiting for
- Accept: To tell the server which type of content the client can process
- Authorization: To send a piece of information to validate the identity of the information consumer
Of course, there are more headers. Refer to https://developer.mozilla.org/es/docs/Web/HTTP/Headers to learn more about the HTTP headers.
