Checkout Integration Types

SlimPay’s Checkout solution offers merchants a frictionless and intuitive payment experience for their customers. Clients can be enrolled through a seamless payment journey, where SEPA mandate and/or document(s) signatures can be obtained in a single transaction.

Here are the available types of checkout integration :

SlimPay checkout :

• Redirection mode: In this case, you have to initiate a create-order, retrieve the checkout link in the API response to redirect the user from your website.
• Iframe mode: Here, you have to initiate a create-order, retrieve the checkout iframe link in the API response, and display it in either embedded or popin to the user, withing your webpage.
• Link mode: You have to initiate a create-order with corresponding parameters, and SlimPay will automatically email the user, containing the checkout link.

You also need to know the payment scheme you intend to use for this customer. If you’re not sure what that is, you probably need to use SEPA Direct Debit CORE.
