We get alot of questions regarding how to set up integration with PCKasse, our UI support provided us with some info. that might help us.
This is how you get a refresh token:
- Your vendor should configure the settings, after that you login with your credentials
- On the POS device, go to "Admin"
- Then press "Oppsett", then "Programinnstillinger"
- Choose the tab, called "Regnskap"
- In the window, called "Regnskapssystem login", press "Koble til eAccounting"
- Log in using your eAccounting credentials
- Make sure the correct boxes are crossed, and press "OK"
- A Token is now generated
- Contact the vendor and inform them that the integration is set up from your side, and they might have to do some more configuration from their side.
