In the Corporate portal, you open the wizard under Issuing & Payments via Add Configuration and choose Conferma as the payment source.
Conferma is an aggregator that lets you connect the virtual card programs of a large number of banks. There are two mechanisms:
Configuration: You select your Conferma issuer (your bank) from the list and enter the client ID, client secret and PKN from your Conferma account. The fields mapping again lets you map accounting fields to your company's data fields.
OAuth connect for Conferma B2B Connect: Here you connect your Conferma B2B Connect account directly via login, without transferring credentials manually.
