Can you explain the main differences between HTTP methods GET and POST?

Main differences between HTTP methods GET and POST:

• GET is used to request data from the server. Parameters are passed in the URL, and the request is considered idempotent and safe (should not change the server's state).
• POST is used to send data to the server, for example, when creating or updating resources. Data is sent in the request body.

Example:

• GET request: GET /users?id=123 — to get information about the user with id=123.
• POST request: POST /users with body { "name": "Ivan" } — to create a new user.

Also, GET requests are usually cached by the browser, whereas POST requests are not.
