HOOK Duplicate order-paid webhook investigation Candidate responding

Question 09 Interview stage

Advanced Difficulty

Webhooks Primary skill

Open response Answer format

An order-paid webhook is retried after a slow response, and the integration creates two fulfilment requests in the ERP.

The candidate must explain webhook delivery behaviour, verify authenticity, identify missing idempotency, protect downstream operations, record processing state, and design safe recovery.

11:18:04.108 webhook topic=orders/paid id=evt-784
11:18:04.391 ERP fulfilment created ref=FUL-501
11:18:09.001 response timeout detected
11:18:12.204 webhook retry id=evt-784
11:18:12.476 ERP fulfilment created ref=FUL-502
11:18:12.590 duplicate operation detected

HMAC

Verify the webhook request

Validate authenticity using the request body and expected signature before processing business actions.

Protect

KEY

Use event-level idempotency

Store the event identity and processing outcome so the same delivery cannot create a second fulfilment.

Resolve

ERP

Protect downstream operations

Include a stable external reference, transaction record, retry policy, and reconciliation process.

Improve

TEST

Verify retry and recovery behaviour

Test duplicate deliveries, delayed responses, process restarts, API failures, ordering, and reconciliation.

Verify

Review the candidate's commerce-integration reasoning.

Evaluate webhook authenticity, event identity, idempotency, downstream consistency, retry strategy, observability, privacy, recovery planning, test coverage, merchant impact, and technical communication.
