How can you tell if an API response has changed?
Every response from the server should have ETag header. Next time when the same set of data is requested ETag should be included in request. Server decides if data has changed since the last call (based on ETag ). If so, 200 is returned along with the new set, otherwise 304 .

POST. In web services, POST requests are used to send data to the API server to create or update a resource. It’s worth noting that a POST request is non-idempotent. It mutates data on the backend server (by creating or updating a resource), as opposed to a GET request which does not change any data.
