Use HTTP Methods

This guideline might sound stupid, but too many times you stumble upon REST APIs which for example do delete operation with parameters /?deleteID=xxx

Use HTTPS methods such instead:

• GET for fetching data.

• POST for adding data.

• PUT for updating data (as a whole object).

• PATCH for updating data (with partial information for the object).

• DELETE for deleting data.

I would like to add that I think PATCH is great way to cut down the size of requests to change parts of bigger objects, but also that it fits well with commonly implemented auto-submit/auto-save fields.
