The way in which you interact with Dwolla’s authorization server will remain unchanged. OAuth user account access tokens that are currently issued to applications leveraging v1 can be used to call various Access API endpoints.
Scopes used in the Access API:
In v1, some API endpoints only require your application key and secret (for instance, creating a checkout or looking up a user), but most require an OAuth access token. In the Access API, all API endpoints require either an OAuth user account access_token or an application access_token in order to authenticate. Application access tokens are new and only used to access protected resources that belong to the application itself including: webhooks, webhook-subscriptions, and events.
For endpoints that require an OAuth access token, it should be included in the Authorization HTTP header like so:
Authorization: Bearer <TOKEN_HERE>.
