Checkout Links

Checkout links are the easiest way to integrate our system. Simply provide the link and we take care of payment, verification and issue the certificate.

You retain full control over the checkout links and can customize them to your exact requirements using various parameters. You can choose between a user-friendly generator for quick set-up or the API for access to advanced functions.
