Re-charge Card

Startbutton's 'Re-charge' feature allows you to charge your customer's card for subsequent transactions after the first charge has been successfully authenticated and completed.

Enable Card Re-Charge

Hey there! Please contact the Startbutton team if you would like to access this feature. With a single API, you can initiate a card re-charge on domestic and international cards.

Complete First Charge

In order for us to ensure that the card is valid and can be charged for subsequent transactions, initializing a first charge is required. You could do this as described here for your customer's first transaction with the card.

The minimum amount we recommend for the first charge is NGN 50.00, GHS 0.10. Lower amounts are not guaranteed to work on all card brands or banks.

Store Card Authorization Code

Once the first transaction is successful (via the initialize transaction endpoint), you should have the webhook payload by listening for webhook notifications or getting the transaction status.

Store the authorizationCode returned to you via the webhook payload or the 'get transaction status' endpoint. This can be used to charge the card subsequently. Avoid saving an authorizationCode multiple times.
