Stripe webhooks: authentic delivery and business-state integrity

Stripe documents duplicate deliveries, unordered events and renewed signatures and timestamps on retries. Signature verification establishes delivery authenticity; it does not establish that the business effect is new or that the event represents the latest application state.

How to use this reference

Editorial lesson: model delivery acceptance, event identity and committed business effects as separate invariants. Review how application state stays consistent across repeated, delayed and concurrent work. A recent authenticated delivery can still describe an already-handled event.

Before reading

  • Basic HTTP webhook and asynchronous processing concepts
  • Basic application state-transition and concurrency concepts

Context and limits

  • Provider-specific guidance, not a universal webhook contract, vulnerability disclosure or exactly-once guarantee. Delivery success does not prove completion of downstream business work.
  • Stripe distinguishes repeated delivery of one event from separate Event objects representing duplicates. Identity rules must follow the relevant event semantics; timestamps alone do not establish order or uniqueness.
  • The signed timestamp concerns a delivery attempt, not the age or ordering of the underlying business event. Provider retries receive new signatures and timestamps.
  • Conceptual defensive education only. No incident, customer loss, patch effectiveness or third-party testing authorization is established.
