IDkollen provides a JSON/REST API for authenticating and signing with BankID.

The API is only accessible with SSL and a unique key provided by IDkollen. The key is private and should not be shared with a third party. The API should only be called from a server application, not directly from the client.

When signing up you will receive API keys for IDKollens staging and live environment.
