Idempotency Request
Idempotency is a concept where a request can be send multiple times with the same result as the first request, that means the system only performs one process for identical requests.
A request is identical if it is sent with the same request-id. However, the implementation may different in other systems, for example for processing transactions additional parameters such as "order-no, amount" may be required to compliment when decide a request is identical or not.
