How to Rotate an API Secret Without Interrupting Webhook Processing

Webhook senders and receivers may rotate a shared secret on different schedules. If the receiver switches too early or too late, valid events can be rejected; accepting both secrets indefinitely weakens control.

What to check

Confirm provider rotation behavior, signature version, overlap window, secret storage, deployment sequence, and rejected event logs. Identify queued retries that may arrive during the transition.

Recommended next step

Coordinate a short overlap when supported, deploy the receiver’s validation update securely, and remove the old secret after confirming delivery. Test a signed event before and after rotation and monitor rejected requests.
