What APIs are available?

The following APIs are available :

• AIS (Account Information Service)
• PIS (Payment Initiation Service)
• CIS (Confirmation of funds)

Further information regarding our APIs can be found after login.

Are the APIs secure?

Security is important to us. The sandbox and the live environment meet the latest security standards. We’ve employed the 0Auth 2.0 consent model to enable clients to grant access to third party service providers (your application) in a clear and secure manner.

How do I access the technical documentation?

Once you have registered you will be able to log in to the Developer Portal to access the technical documentation of our APIs.

What can be done in the sandbox?

Our sandbox provides an opportunity for developers to test their app before building in production. The sandbox is a safe, secure environment where you can test your apps functionality and test our API integrations with your apps.
