  10. Idempotency advanced Multiple choice

    A billing platform sends a webhook, the customer's endpoint times out, and the customer's system retries the operation several times. How should idempotency keys, durable event state, delivery attempts, ordering and reconciliation prevent duplicate billing?

  12. Idempotency advanced

    A payments API receives the same charge request twice because a mobile client retried after a timeout. How should idempotency keys be scoped, stored, expired and validated, and what happens when the first attempt is still in flight?
