How to Handle API Webhooks That Arrive Out of Order

Webhook delivery order is not always guaranteed, so applying events as received can restore older state over newer state.

Checks to make

Use event timestamps or version numbers when supported, persist event identifiers, and reject stale state transitions. Reconcile against the source API when ordering is ambiguous and test delayed and duplicated events.
