Apple Pay and Google Pay

Apple Pay and Google Pay​

Both Apple Pay and Google Pay services are part of the Comgate payment gateway. To view customer services, you only need to have the CARD_CZ_COMGATE or CARD_CZ_CSOB_2 card payment method enabled.

Recurring and verification payment functionality cannot be used within the service. Other functionalities are available.

Displaying services​

The display of both Apple Pay and Google Pay services depends on whether the selection of payment methods is in the e-shop cart or the e-shop uses the selection of methods from Comgate. It is also necessary to distinguish whether the payer should be redirected to the card gate or Apple Pay or Google Pay will be displayed directly in the e-shop cart.

We therefore distinguish three possibilities of displaying:

  1. The button in the card gateway - If the choice of payment methods is on the Comgate side, no modifications are required to display the services. It is sufficient to have the card payment method CARD_CZ_COMGATE or CARD_CZ_CSOB_2 enabled. After the payer has selected one of these methods, the payment is made through the standard process with redirection to the payment gateway, where the services are displayed automatically. Here, the payer is also allowed to manually enter the card number. If the payer reaches the gateway from a device or browser that does not support any of the services, the payer will be able to make at least a payment by credit card.

  2. The button in the e-shop's cart with the redirection of the payer to the card gateway - If the choice of payment methods is on the side of the e-shop, the payment is based as a regular payment, however, in the request you need to call the APPLEPAY_REDIRECT or GOOGLEPAY_REDIRECT method. Subsequently, the payer is redirected to the payment gateway using the obtained payment link. Both Apple Pay and Google Pay buttons will then appear automatically on the card gateway. Subsequently, the payment process from the payer's point of view is identical to the first option. We recommend that you follow our Google Pay and Apple Pay Button Display Policy, which are available below.

  3. The button in the e-shop's cart with the redirection of the payer to the card gateway This integration option does not redirect the payer to the card gateway and the payment is completely processed directly in the e-shop environment. Implementation of this behavior is more challenging than both of the above mentioned options. For this purpose, you must use our prepared JavaScript library Checkout SDK. Detailed information on the integration process can be found in Checkout SDK documentation section.

If the merchant does not check the availability of Apple Pay and Google Pay on their side, this method may not be available as a result, even if the payer chose it in the e-shop cart. The payer is then offered a standard payment by card with a copy of the data.

Button display policy​

Apple Pay in shopping cart​

Apple Pay is only available to users who have a Safari web browser and a custom Apple device that has a Touch ID or Face ID. These devices include MacBook, iPhone, iPad and desktop Mac. For this reason, we recommend that you display the service in your order only to clients who can pay with Apple Pay. Instructions can be found directly at Apple's developer site.

The easiest way to verify this is through:

if (window.ApplePaySession) {
   // Apple Pay JS API is available => we are on a supported device

   window.ApplePaySession.canMakePayments()
     .then((result) => {
         // device is able to make payments using Apple Pay
     })
}

There are also several requirements required by Apple:
