13. Review audit history

Audit records show who or what initiated a supported action, when it occurred, the affected resource, and the recorded outcome. Use Audit before repeating a request that timed out or appears uncertain.

Investigate an operation

1. Open Audit.
2. Filter by event type, resource, date, or operation identifier.
3. Follow linked receipt, transfer, count, bill, or correction records.
4. Compare prepared, committed, failed, retried, uncertain, and reconciled events.
5. Export the filtered ledger for internal sign-off or support.

What idempotency means

An idempotency key identifies one exact operation. Repeating that operation with the same payload and key should not apply it twice. Changing the payload while reusing a key is rejected. Creating a fresh key for an uncertain old operation is unsafe because Shopify may already have applied the first request.
