Getting Started - Authorization


finAPI follows the OAuth 2.0 Standard for authorizing applications and users within them. OAuth uses the terminology of clients and users. A client represents an application that calls finAPI services. A service call might be in the context of a user of the client (e.g.: getting a user's bank connections), or outside any user context (e.g.: editing your client's configuration, or creating a new user for your client). In any case, every service call must be authorized by an access_token. The documentation below describes how to set up the client's users, or for the client itself.

To make authorization processes and user management easier finAPI offers 2 ways to use the services.

Regardless of that, use cases can be divided into two basic scenarios.
