How to review webhook recovery and failed-event queues

Published by Phantom Workflow • Editorial contact: Kurt James

Last reviewed:

A webhook workflow should verify incoming events, record processing state, and define how failures are retried or reviewed. Check the provider's delivery semantics before assuming events arrive once or in order. A failed-event queue needs an owner and a safe replay procedure; storing a failed notification alone does not resolve the underlying work.

Planning guidance based on the sources below. These are proposed workflows, not completed Phantom projects or client results. Account access and suitability require separate verification.

Scope the buyer decision

A recovery design should distinguish receiving an event from completing its business action. Record which operation succeeded before retrying, especially after a timeout with an uncertain result. Use provider-supported idempotency where available, and verify the final business record rather than treating a successful HTTP acknowledgment as completion.

Proposed workflow and ownership

This table is a planning checklist. Confirm the account's supported access and the business's rules before implementation.

ReceiveValidate the event and record its identity before processing.
ProcessTrack the business operation and any uncertain result.
RecoverAssign failed work to an owner with a reviewed retry procedure.

Failure cases to review

Use these scenarios to define exceptions and staff ownership for this workflow.

  • A repeated notification repeats a business action.
  • An out-of-order event overwrites a newer state.
  • A failed-event queue grows without review or safe replay.

Pilot acceptance checks

Test repeated events, altered signatures, out-of-order delivery, and a timeout after a successful write. Confirm retries do not repeat the completed action and that failed work has an owner.

Questions to resolve before a pilot

Does adding a queue guarantee no lost work?

No. A queue is one component. Review event retention, acknowledgment timing, recovery ownership, and the final business state through failure tests.

What should a pilot test?

Test repeated events, altered signatures, out-of-order delivery, and a timeout after a successful write. Confirm retries do not repeat the completed action and that failed work has an owner.

Which documented options are relevant to this workflow?

Stripe documents duplicate event delivery and does not guarantee event delivery order. Stripe documents webhook signature verification using the original request body and endpoint secret. Stripe documents idempotency keys for safely retrying supported requests without repeating the operation. Verify the permitted operations and account access for the intended pilot.

What should remain under staff control in this workflow?

An assigned operator reviews failed events, decides which can be replayed safely, and resolves items that need manual handling. Set a review interval so the queue cannot grow unnoticed.
