Have you tested request idempotency? How exactly?

Yes, I tested the idempotency of requests, especially for PUT and DELETE methods.

How I tested:

1. Sent requests with the same parameters multiple times in a row.
2. Checked that the server response and resource state do not change after the first successful request.
3. Ensured that the status code and response body match expectations (e.g., 200 OK or 204 No Content).

Example for PUT:

• Send a PUT /resource/1 with a specific body.
• Verify that the resource has been updated.
• Repeat the same PUT request.
• Check that the resource has not changed further and the response is the same.

This way, I ensure that repeated requests do not lead to unwanted side effects.
