Which HTTP method is not idempotent by definition, so retrying it can create a second resource?

Options

• ✗ GET
• ✗ PUT
• ✗ DELETE
• ✓ POST Correct

Why

PUT and DELETE leave the same state however often they are repeated. A retried POST can charge a card twice unless the API takes an idempotency key and remembers the requests it has already processed.
