# Start a real-human verification session

`POST /asset/real-human/sessions`

Begin creating a **real-human (LivenessFace)** asset group. Returns an
H5 link the end user opens to complete a one-time face verification.
After they finish, the verification page redirects their browser back
to an OrcaRouter callback (handled for you), and the new group is
registered. Poll `GET /asset/real-human/sessions/{session_id}` for the
result. The end user's device does **not** need to be logged in.

## Request body

- object — Any field other than `return_url` is forwarded as-is to the upstream verification call, so you can pass any parameter the asset service supports. `CallbackURL` and `ProjectName` are set by OrcaRouter and cannot be overridden.
  - `return_url` string — Optional http(s) URL the end user's browser is redirected to after verification, with `?status=&session_id=&group_id=`. Omit to show a built-in completion page.

## Response `200`

Session created

- object
  - `session_id` string
  - `h5_link` string
  - `status` string
