Approaches to achieving idempotency include: assigning a unique request ID to each call, with the execution layer recording completed calls and returning cached results on retries; handling external interfaces that cannot be made idempotent through deduplication keys or compensatory transactions.

UnverifiedCommon approaches to achieving idempotency include assigning a unique request ID (Idempotency Key) to each operation, which the server uses for deduplication.78% similarUnverifiedPrompt caching is a capability of the Anthropic API: when the prefix portion of a request is exactly identical to the previous request, the server can reuse the already-computed intermediate state and skip redundant prefill computation.74% similarUnverifiedIn scheduling scenarios, blind retries without an idempotency key may generate two identical appointments, occupying another customer's time window; the correct approach is to resubmit with the request ID, and the server uses the idempotency key to determine whether it is a first execution or a duplicate request.74% similarVerifiedA common technique for achieving idempotency is for the client to generate a unique idempotency key sent with the request, while the server records the result associated with that key and returns the cached result upon receiving a duplicate request.72% similarUnverifiedDesigning a foreign key linking the job ID to the charge record makes refunds, customer support and duplicate detection possible.72% similar
