You have the option to choose between the payment page option that redirects the merchant to a fully customizable payment page or the embedded iframe option that integrates your checkout seamlessly without redirection.

Option 1

Individual Payment Page

The payment page offers a payment form for desktop, tablet, and mobile devices. The technical integration is easy and we offer a default template that has been tested thoroughly and works for desktop, mobile and tablet devices out of the box.

The payment page is the easiest way for you to integrate the payment methods and let us care for all the complexity and challenges the different payment methods create. We collect all the payment information necessary to process the payment. In case information is missing we are simply asking your customer for the information. This makes it a lot easier for you to expand and scale your business into new markets. Beside credit cards you are able to process additional payment methods like TWINT, Direct Debits, PayPal, Paydirekt or Sofort.

Mobile Ready Checkout

In order to process payments, no matter on what device, wallee enables you to offer shoppers the option to pay with our full range of payment methods, including all major card schemes, wallets, E-Banking accounts and even more local methods.

One-Click and One-Touch Checkout

In the mobile first age you want to reduce the necessary steps to purchase for your customer. Your customers want a streamlined experience so they can focus on what actually matters: choosing the appropriate items when shopping online. We love payment but we also know that payment has to be happen reliably in the background. This is particularly true of loyal consumers that generate repeat sales for online merchants. This is why we enabled the one-click checkout or the one-touch payment on mobile devices. This creates a frictionless experience that meets consumer expectations and generates a higher level of sales for merchants. This process relies on tokenization.

Tokenization is the process of associating unique identifiers called tokens to payment data such as payment card details. At the time of payment, the token of a payment card is sent from the merchant’s website to the payment provider, who links the token to the stored payment details and sends the authorization request.
