Authentication

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

This is the endpoint used for production environments:

https://id.aritma.io/connect/token

Note:

For development use: https://id.dev.aritma.io/connect/token

Scopes

Scope	Description
`bankservice`	Access to the Open Banking API

Grant Types

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

The Open Banking API supports the following grant types:

Scope	Description
`client_credentials`	Client Credentials Grant
`authorization_code`	Authorization Code
`password`	Resource Owner Password Grant
`implicit`	Implicit Grant
