Main differences between POST, PUT, and PATCH methods:
-
POST — used to create a new resource on the server. Usually sends data based on which the server creates a new object. The method is not idempotent (repeated requests may create multiple resources).
-
PUT — used for complete update of an existing resource. The client sends a full representation of the resource, and the server replaces the current one with it. The method is idempotent (repeated requests with the same data will not change the result).
-
PATCH — used for partial update of a resource. The client sends only the changed fields, and the server updates them without affecting others. The method is not always idempotent, depending on implementation.
Example usage:
- Create a new user — POST /users
- Update the entire user profile — PUT /users/123
- Change only the user's email — PATCH /users/123
The choice of method depends on the task and API requirements.
