The short answer
Rotate cutover credentials by inventorying every integration identity and secret owner, creating target credentials with minimum scope, testing them safely, switching endpoints and schedules at a recorded boundary, revoking the old credentials, and reconciling events across an overlap window. Configuration success is not proof of event continuity.
Key takeaways
Inventory credentials, endpoints, and hidden dependents
List API keys, OAuth grants, service accounts, webhook signing secrets, SFTP users, email ingestion addresses, scheduled exports, bank connections, payment-provider tokens, and automation accounts. Record owner, environment, scope, dependent workflow, storage location, expiry, and revocation method without copying secrets into the register.
Map whether a rollback would need the old identity and who may extend that window. An undocumented script or vendor-managed connector can keep using the source after staff believe cutover is complete.
Use an observable rotation sequence
Create the target credential with least necessary scope, test a non-consequential call or sandbox path, configure the target, record the last source checkpoint, enable the new flow, and monitor receipts before revoking the old credential.
| Stage | Proof | Failure response |
|---|---|---|
| Target ready | Authentication plus bounded capability test | Correct scope; do not broaden by default |
| Flow switched | Endpoint/schedule/config version and time | Return to approved rollback state |
| Overlap reconciled | Source/target event IDs and counts | Replay or resolve through event register |
| Old access revoked | Provider/system confirmation and test | Escalate remaining dependent |
| Ownership transferred | Named operator and monitoring window | Keep exception open |
Reconcile the rotation window
Check events created shortly before and after the boundary, including delayed webhooks, retries, scheduled jobs, and manual actions. Stripe advises webhook consumers to handle duplicate events and not depend on delivery order; that illustrates why event IDs and object state should be reconciled rather than counting requests alone.
Retain missed, duplicate, unauthorized, or out-of-order events as exceptions. Revoke source access only under the approved rollback and continuity decision, then verify that the old identity no longer works where a safe test is possible.
