Checkout integrations types




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

Pop-in mode

Pop-in mode will display the Checkout in a frame overlaying the merchant's website content, without changing web pages.


iFrame mode

iFrame mode seamlessly integrates the Checkout into the content of a merchant's website.


Redirect mode

Redirect mode will display the Checkout on another web page with a different URL. Customers will be redirected to a page hosted by SlimPay or by the merchant. In order to personalize the URL, merchants will need to activate our white label customisation options.
