Unverified50% confidenceSolutionExact time
A common practice for achieving idempotency is to generate a unique operation identifier (Idempotency Key) for each operation; the server first checks whether that ID has already been processed upon receiving a request, and if it has been completed, returns the original result directly without re-executing.
