Manage payment page

Manage payment pages

Overview

To be able use the Payment Page integration with the PHP SDK, you must create a Paypage instance and initialize it using the Unzer object. As a result you get an ID and a redirectURL which can be used to show the Payment Page:

  • Use the Payment Page ID to render the embedded Payment Page as described in Embedded Payment Page guide.
  • Or redirect your customer to the redirectURL to use the hosted Payment Page as shown in the Hosted Payment Page guide.

Initialize a Payment Page

To initialize a payment page, you require at least an amount, a currency and the returnUrl.
Optional parameter for the API request can be added to your paypage instance using the setter function of the given property as demonstrated in the example below.

For a full list of parameters, see the API reference guide.
