# PayoutID

PayoutID is Payout's [OAuth2](https://oauth.net/2/) and [OpenID Connect](https://openid.net/) provider. Payout uses it internally, and third parties can use it to:

- authorize users and issue access tokens: [PayoutID OAuth2](https://developers.payout.tech/guides/payout-id-oauth.html);
- access the [Banklink API](https://developers.payout.tech/guides/banklink.html) on behalf of a user: [Banklink authorization](https://developers.payout.tech/guides/payout-id-banklink.html);
- access the [OpenBanking PSD2 API](https://developers.payout.tech/guides/psd2.html);
- verify the identity of their customers: [Identity verification](https://developers.payout.tech/guides/payout-id-identity-verification.html).

The endpoints are described in the [PayoutID API reference](https://developers.payout.tech/api/payout-id.html).
