<div className="dj-endpoint">
  <span className={`dj-method dj-method-post`}>POST</span>
  <code>/api/v1/kyc/bvn/verify</code>
</div>

Match a user’s selfie against the photo held for their Nigerian BVN or NIN, and retrieve the full identity record in the same call.

## Headers

| Header          | Required | Description                                         |
| --------------- | -------- | --------------------------------------------------- |
| `Authorization` | Yes      | Your app's secret key, sent as-is — *not* `Bearer`. |
| `AppId`         | Yes      | The App ID from your dashboard.                     |
| `Content-Type`  | Yes      | `application/json`                                  |

## Body parameters

| Parameter      | Type   | Required | Description                                                                        |
| -------------- | ------ | -------- | ---------------------------------------------------------------------------------- |
| `bvn / nin`    | string | Yes      | The identifier to verify — `bvn` for the BVN endpoint, `nin` for the NIN endpoint. |
| `selfie_image` | string | Yes      | The selfie image, Base64-encoded (strip the `data:image/jpeg;base64,` prefix).     |
| `bvn`          |        | No       |                                                                                    |

## Response

The BVN endpoint returns the BVN identity record with a nested `selfie_verification` object (`confidence_value` and `match`). Response trimmed for readability.

## Verify NIN with a selfie

Call `POST /api/v1/kyc/nin/verify` with `nin` and `selfie_image` (and optional `first_name` / `last_name`) to match a selfie against the photo on file for a NIN. It returns the NIN identity record with the same `selfie_verification` object.
