What does the interaction between the front end and back end look like when confirming? What HTTP method is called and what is the endpoint called?

When confirming on the frontend, an HTTP request is usually sent to the backend to record the user's action.

• HTTP Method: most often POST, as confirmation involves creating or changing a state on the server.
• Endpoint: usually named according to the action's meaning, for example /confirm, /orders/{id}/confirm, or /api/confirm.

Example interaction:

POST /api/orders/12345/confirm HTTP/1.1
Host: example.com
Content-Type: application/json

{"userId": "67890"}

The server processes the request, changes the order status to "confirmed," and returns the result.
