GTM integration credential lifecycle rotation

GTM integration credential lifecycle

Every marketing and sales tool that calls another system needs a known credential with an owner, a purpose, and a rotation date. An invisible credential becomes a shared secret that no one can responsibly change.

The lifecycle should keep a credential discoverable, limited to its purpose, and replaceable on schedule without breaking the integrations that rely on it.

Inventory the credentials

List every integration by the source system, the destination, the credential name, the scope, the owner, and the last confirmed use. Regenerate this inventory on a regular cadence so it does not silently decay.

Mark credentials that are embedded in source code, copied into documents, or shared across environments as higher risk. Knowing where each secret lives is the first step to managing it.

Grant least privilege

Scope each credential to the exact capabilities the integration needs and no more. A read only token should not carry write access, and a test credential should not reach production.

Review whether each scope is still necessary on the same cadence as rotation. Removing an unused permission is safer than assuming an old token never fires.

Rotate on schedule

Set a rotation date for every active credential and a backup owner who can perform it. Test the rotation in an approved environment before the live switch.

Record the old and new values without pasting secrets into chat or issue threads. If a credential is shared, rotate it and update every consumer in a coordinated run.

Recover safely

Define the recovery path when a rotated credential stops an integration. Revert to a known good value, restart the consumer, and confirm the identity that failed.

Do not widen permissions to make an integration work again. Fix the correct scope and retest instead of granting broad access as a shortcut.

Close the lifecycle record

Reconcile active, rotated, retired, and recreated credentials against the inventory. Retire credentials that no integration uses and record the evidence of removal.

Review the inventory for expired tokens, unknown owners, and broad scopes on the same cadence. Route a suspected exposure through the accountable security path.
