# Renew the FaceTec session token

POST https://client.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`).


Reference: https://docs.api.corpx.com/ib/referencia/identity-verification/renew-identity-verification-face-tec-session

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Path parameters

- `verificationId` (string, required) — Standalone identity verification identifier returned by the creation endpoint.

### Headers

- `X-Tenant-Id` (string, required) — Tenant context used for authorization and routing.
- `X-FaceTec-User-Agent` (string, optional) — Value of `FaceTecSDK.createFaceTecAPIUserAgentString("")` from the SDK. Recommended.
- `Idempotency-Key` (string, optional) — Optional client-generated idempotency token (recommended for safe retries).
- `X-Request-Timestamp` (string, required) — Unix seconds. Required on the signed host; tolerance is 300s either way (`403 request_timestamp_skew`).
- `X-Content-SHA256` (string, required) — Lowercase hex SHA-256 of the body. An empty body hashes the empty string, so the header is always present. Mismatch returns `400 body_hash_mismatch`.
- `X-Request-Signature` (string, required) — Detached JWS (`<protected>..<signature>`, ES256 or PS256) over `METHOD\nPATH?QUERY\nTIMESTAMP\nIDEMPOTENCY_KEY_OR_EMPTY\nX_CONTENT_SHA256`.

## Response

### 200

New session token.

- `verificationId` (string, required)
- `sessionToken` (string, required)
- `sessionTokenExpiresAt` (datetime, required)
- `attemptsRemaining` (integer, required)
