# List verification attempts

GET https://api.withverifa.com/api/v1/sessions/{session_id}/verifications/{policy}/attempts

Returns all attempts for a specific verification policy on a session,
including previous failed attempts. Useful for audit trails and
investigating retry history.


Reference: https://docs.withverifa.com/api-reference/sessions/list-verification-attempts

## Authentication

- `X-API-Key` header (required) — Organization API key. Keys are prefixed with `vk_live_` (production) or `vk_sandbox_` (sandbox).

## Request

### Path parameters

- `session_id` (string, required) — Session ID (`ses_*`).
- `policy` (string, required) — The verification policy (e.g. `face_match`, `document_ocr`).

### Headers

- `Verifa-Version` (date, optional) — API version date string (e.g. `2026-02-01`). If omitted, the version pinned to your API key is used.
- `Key-Inflection` (enum, optional, default: snake) — Response key casing. Defaults to `snake`.
  - Allowed values: `camel`, `kebab`, `snake`

## Response

### 200

Verification attempts for the policy.

- `session_id` (string, required)
- `policy` (string, required)
- `attempts` (list of VerificationCheck, required)

## Errors

### 401 Unauthorized Error

Missing or invalid API key.

- `error` (string, required) — Short error code.
- `status_code` (integer, required) — HTTP status code.
- `detail` (string, optional) — Human-readable error description.

### 404 Not Found Error

Resource not found.

- `error` (string, required) — Short error code.
- `status_code` (integer, required) — HTTP status code.
- `detail` (string, optional) — Human-readable error description.

## Types

### VerificationCheck

- `id` (string, required)
- `policy` (string, required) — The verification policy (e.g. `face_match`, `document_ocr`).
- `status` (enum, required)
  - Allowed values: `pending`, `running`, `passed`, `failed`, `error`, `requires_retry`, `skipped`
- `passed` (boolean, required, nullable)
- `attempt` (integer, required)
- `details` (map from string to any, optional, nullable) — Policy-specific result fields. **Vendor names are scrubbed at the API boundary** — the `providers` array (and any other provider-shaped field) returns sanitized category labels such as `aml_screening` or `address_verification`, never raw vendor identifiers like `complyadvantage`, `smarty`, `ipqs`, or `telesign`. See `vendor-scrubbing.md`. For `proof_of_address_check` the shape is documented as `ProofOfAddressDetails`.
- `duration_ms` (integer, optional, nullable)
- `started_at` (datetime, optional, nullable)
- `completed_at` (datetime, optional, nullable)
