This article only concerns our merchants using technical integration.
We propose the save card feature thanks to our new API version (2.0 version).
The save card feature is dedicated to our Pro subscribers only.
This feature is only available in technical integration and it allows, among all, to receive payments in several installments.
In order to implement this payment option, it is necessary to activate the "save_card" parameter which is related to the action of saving a card, changing it to "true".
Once the credit card deposit activated, when a payment is done, the payment notification will generate an id "card ID" which will be stored on your configuration and will be called when you will charge your customer's credit card.
The documentation for this feature is available here.
If you are interested by the several installment payment (2, 3, 4 installments), you can look at the article there.
