Idempotency key mechanism: assign a fixed ID to each action and send the same ID on retries, and the payment system will reject duplicate requests; OpenAI's documentation also recommends this practice.

UnverifiedA common way to handle duplicate operations caused by retries is to carry a unique idempotency key in the request, letting the receiver determine from that key whether the same operation has already been processed, thereby safely ignoring duplicate requests.77% similarUnverifiedAn idempotency key generates a unique identifier for each state-changing operation, enabling external systems to recognize and avoid duplicate execution, and is standard practice in critical business scenarios such as payments and orders.74% similarUnverifiedIdempotency keys combined with retry mechanisms are the industry-standard practice for strongly consistent scenarios such as payments and orders, but require that the called tool or API itself supports idempotent semantics.69% similarUnverifiedCommon means of achieving idempotency include: assigning a unique request ID to each operation and deduplicating on the storage side; using optimistic locking or version numbers so that duplicate writes are rejected; and designing operations to set a final state rather than make incremental modifications.68% similarUnverifiedThe idempotency key must come from stable input features (such as meeting ID or item content hash) and must not depend on the order or random IDs of this run, otherwise the key will change on rerun and deduplication will fail.67% similar
