Checkout Integrations types


Checkout, the SlimPay interface that enables debtors (customers) to sign documents or mandates and to make payments can be integrated on the subscription or payment process in different ways. In order to better adapt to each merchant needs, SlimPay offers 3 Checkout integration modes. 

Pop-in mode

The Pop-in mode allows to display the Checkout overlaying the merchant website content, without changing pages.


iFrame mode

The iFrame mode allows to seamlessly integrate the Checkout in the merchant website.


Redirect mode

The Redirect mode allows to display the Checkout on another page with a different URL. This page can be hosted by SlimPay or by the merchant. In order to personalize the URL, the merchant has to activate our White Label offer.
