# /register\_face

#### Endpoint

```http
https://be.progeny.tech/api/v3/services/register_face/
```

#### Purpose

Allows you to connect to the Liveness service, using the provider configured in the **Progeny Console**, to register a face image in database.

If the image passes the liveness check, the result is a UUID.

If the image does not contain a face, only contains a partial face, or if the quality of the image is too low, we will return  an error code, for example `FACE_TOO_SMALL` . See our image requirements above for more information.

{% hint style="info" %}
Please refer to the section on [images](/our-api/overview.md#a-quick-word-about-images) for guidance before posting.  For the best results, we recommend a maximum height of 1080px.
{% endhint %}
