Steps
Configure a webhook endpoint in the Veriff Station dashboard and set the X-HMAC-SIGNATURE secret
On receipt, validate the signature by computing HMAC-SHA256 of the raw body with the secret and comparing to the header value
Parse the verification.status field: approved, declined, resubmission_requested, review, or expired
For declined and resubmission_requested statuses, read the verification.reason and verification.reasonCode to determine the specific failure (e.g., 105 = document not supported, 106 = face not found)
Route the user based on status: approved triggers downstream provisioning, resubmission_requested returns the user to the flow, review queues the session for analyst inspection
Known gotchas
Veriff can send multiple decision webhooks for the same session if a review decision is later overridden; always process the latest event by decision timestamp
The resubmission_requested status is not a final decision; do not close the verification attempt until you receive approved, declined, or expired
Webhook events for expired sessions fire after the session TTL (default 7 days); monitor for this to clean up incomplete onboarding records
