When you are starting to use Fenerum there is a good chance that you already have a payment gateway system (like Stripe or QuickPay) up and running.
You have two possible ways to safely import already existing credit card information into Fenerum.
Use our API
We have a dedicated endpoint for gathering a credit card info based on it's unique identifier in your PSP system and then storing card's representation in Fenerum.
It should be fairly easy to write a short script that goes through you current cards' ids and hits our endpiunt for each of them. You'll find more info in our API docs.
Import data from file
If your provider supports exports of your current data it may be even easier to import your data by uploading a csv/excel file in a correct format.
For details see our guide on file imports.
