Currently test transactions for iDEAL and bank transfers are possible.
Unfortunately it is not yet possible to carry out test transactions for credit and debit cards.
Each payment option works in the same way for the integration.
We have a generic Kassa Compleet API.
If iDEAL works in the test environment through the API, then the credit and debit cards will also work, as will any other payment option.
The credit card details are stored in a secure location.
This location has been extensively tested and is certified for PCI DSS.
This is the industry security standard for the large credit card companies that focuses on protecting card details.
