# Renew the FaceTec session token

POST https://tenant.api.corpx.com/v1/identity-verifications/{verificationId}/facetec/session

Issues a new FaceTec session token for a pending `method: facetec_sdk`
verification. Tokens live **10 minutes** at the provider; the one
returned by the create is enough when the camera opens right away.
Call this route when the app comes back from background, when
`/facetec/process` answered `facetec_session_expired`, or right before
opening the camera after a long wait. It can be called at any time
while the verification is `PENDING`.

Throttle: at most **1 renewal every 5 seconds** and **30 per
verification** (`429 facetec_session_renewal_limited`).
