  title: Veriff Public Attempts Decisions API
  description: "The Veriff Public API powers online identity verification: creating verification sessions, submitting and retrieving media, and reading the resulting decision, person, watchlist-screening, and attempt data.\n\n## Base URL\n\nRequests are made against your integration base URL, retrieved from the Veriff Customer Portal (API Keys page). The common production base URL is `https://stationapi.veriff.com/v1`.\n\n## Authentication\n\nEvery request carries two headers:\n- `X-AUTH-CLIENT` - your integration's public API key, identifying the\n  request sender.\n\n- `X-HMAC-SIGNATURE` - a hex-encoded HMAC-SHA256 signature proving payload\n  authenticity, computed with your integration's shared secret key.\n\n\nWhat is signed depends on the method:\n- `POST` / `PATCH`: sign the exact raw request payload body.\n- `GET` / `DELETE`: sign the resource identifier used in the path\n  (for example the session ID).\n\n- `POST /sessions` is the one exception and does not require\n  `X-HMAC-SIGNATURE`, only `X-AUTH-CLIENT`.\n\n\nVeriff signs its responses and webhooks the same way, returning `vrf-auth-client`, `vrf-hmac-signature`, and `vrf-integration-id` headers so callers can verify authenticity."
