Authentication

The PSD2 API uses OpenID Connect with the OAuth 2.0 standard for authenticating access tokens. Your access token authorizes you to use the PSD2 API.

This is the endpoint used for production environments:

https://id.zdata.no/connect/token

Note:

For development use: https://id-dev.zdata.no/connect/token

Scopes

Scope	Description
`banking.channel.psd2`	Access to PSD2 API's
`banking.ais.read`	Access to Account Information API's

Grant Types

The OpenID Connect and OAuth 2.0 specifications define so-called grant types (often also called flows - or protocol flows), which specify how a client can interact with the token service.

The PSD2 API supports client credentials grants which means you need a ClientID and Client Secret which can be exchanged for an access token that grants access to the API.
