# Create Real-Person Verification Session

> Creates a TokenLab real-person material verification H5 session.

Create a short-lived verification session and redirect your user to the returned H5 link. TokenLab returns only neutral fields: `session_id`, `verification_token`, `h5_link`, `callback_url`, `expires_in`, and `language`.

The session, token, and H5 link expire after 120 seconds. When the H5 flow completes, TokenLab redirects to your original `callback_url` with these query parameters:

| Parameter             | Meaning                                 |
| --------------------- | --------------------------------------- |
| `session_id`          | TokenLab verification session ID.       |
| `verification_token`  | Opaque token used to bind the result.   |
| `verification_status` | `succeeded` or `failed`.                |
| `result_code`         | Result code for your application logic. |

If `verification_status` is `succeeded`, call [Bind Real-Person Verification Result](/de/api-reference/video/bind-real-person-verification-result). The [test console](https://tokenlab.sh/dashboard/seedance-assets) can be used to verify callback handling before you wire the flow into your product.
