Charging Cards

Once you have a card token representing your user's card from Components - the next step is to charge that card for the money. This has to be done on your server by making a simple request to our API.

Note that a card token is a temporary representation of card details - it has to be used within 24 hours after creation. Otherwise, it will expire.

This example shows how to create a charge from card: cardToken

Shift4Gateway shift4 =
    new Shift4Gateway("pr_test_tXHm9qV9qV9bjIRHcQr9PLPa");

ChargeRequest chargeRequest = new ChargeRequest(799, "USD")
    .card(new CardRequest(cardToken));
Charge charge = shift4.createCharge(chargeRequest);

After successfully creating a charge, you should see it on charges list in your dashboard.

More information about creating charges can be found in API references.

Card tokens are for one-time use only. Once you create a charge from a token, that token can't be used to do anything else. To avoid asking the user for their card data every time you create a charge, you must create a customer with a card.

This example shows how to use card token to create a customer with a card and how to create a charge on that customer's card

Shift4Gateway shift4 =
    new Shift4Gateway("pr_test_tXHm9qV9qV9bjIRHcQr9PLPa");

CustomerRequest customerRequest = new CustomerRequest("user@example.com")
    .card(new CardRequest(tokenId));
Customer customer = shift4.createCustomer(customerRequest);

ChargeRequest chargeRequest = new ChargeRequest(799, "USD")
    .customerId(customer.getId());
Charge charge = shift4.createCharge(chargeRequest);

More information about creating customers can be found in the API references.
