Verifications

A verification is one identity-check session for one end user. Create it on your server, hand the client token or hosted URL to the user's browser, then read the decision. All four endpoints are merchant-authenticated with X-Api-Key.

Create a verification

POST/v1/verificationsscope verifications:write

To create a verification, POST /v1/verifications with an optional external_ref (your user's id), an optional free-form user object, and an optional redirect_url the hosted flow returns to when finished. The API creates the verification in status created (expires in 24 hours) and issues a 30-minute client_token for the hosted flow.

Request body

Field	Type	Description
external_refoptional	string \| null	Your idempotency/reconciliation handle. Stored verbatim and returned on every read.
useroptional	object	Free-form metadata about your user (e.g. email, internal id). Defaults to `{}`.
redirect_urloptional	string \| null	URL the hosted flow navigates to after completion (used by redirect-style integrations).

201 Created — response body

Field	Type	Description
idrequired	uuid	Verification id. Use it for GET calls and to reconcile webhooks.
client_tokenrequired	string	30-minute token for the hosted flow (`X-Client-Token`). Deliver it to the browser.
urlrequired	string	Fully-built hosted-flow URL (`{HOSTED_BASE_URL}/verify/{id}?token=…`). Redirect or link the user here.

JSON201 Created

  "client_token": "x7Qp9m2LwR4tY8uZcVbN1sDfGhJkL0oP3eA5qW6rT2y",

}

Client token lifetime

The client token expires after 30 minutes while the verification itself lives 24 hours. If a user abandons the flow and returns later, create a new verification — do not try to reuse a stale token.

List verifications

GET/v1/verificationsscope verifications:read

To list your verifications, GET /v1/verifications. Results are scoped to the calling API key, newest first. Use status to filter by lifecycle state.

Query parameters

Field	Type	Description
limitoptional	integer (query)	Page size, 1–200. Default 50.
offsetoptional	integer (query)	Rows to skip. Default 0.
statusoptional	string (query)	Filter by exact status, e.g. `decided`.

Retrieve a verification

GET/v1/verifications/{verification_id}scope verifications:read

To retrieve a verification — including the full decision, every document check, the consent record and the hash-chained audit log — GET /v1/verifications/{verification_id}. Verifications belonging to a different API key return 404 verification not found (never 403 — existence is not leaked).

Beyond the summary fields, the response adds decision_reasons, a checks object (doc_checks, face_match_score, liveness_score, license_fields), the consent record, and events — the ordered, hash-chained audit trail. Every check id in doc_checks is explained in the decision object reference.

Get verification media

GET/v1/verifications/{verification_id}/mediascope verifications:read

To download the captured images, GET /v1/verifications/{id}/media. The media bucket is private — the only access path is the short-lived presigned URLs returned here. Links expire after 3600 seconds (1 hour); call the endpoint again for fresh links. Every issuance is audit-logged as media.links_issued. In local-fallback deployments without S3, url and expires_in are null.

The verification object

Summary shape returned by the list endpoint and embedded in every verification response:

Verification summary fields

Field	Type	Description
idrequired	uuid	Verification identifier.
external_refoptional	string \| null	Your own reference, echoed back.
statusrequired	string	Lifecycle state: `created`, `consented`, `doc_front`, `doc_back`, `selfie`, `submitted`, `processing`, `decided`.
decisionrequired	string \| null	`approve` \| `review` \| `decline`; null until decided.
scorerequired	number \| null	Composite score 0–100. Bands: ≥ 80 approve, 50–79 review, < 50 decline.
created_atrequired	ISO 8601	Creation timestamp.
expires_atrequired	ISO 8601	Creation + 24 hours.

The decision fields (decision, score, decision_reasons) are populated when the user submits and the decision engine runs — see the decision object for scoring, bands and every reason string.
