The payment gateway provides the option to use an iframe to seamlessly integrate the payment pages into your website, allowing your customers to make payments without leaving your site.
Using the iframe mode requires the merchant website to use the HTTPS protocol on all of its pages. This is necessary to ensure secure communication between the merchant's website and the Nilon gateway, providing a safe environment for processing payment transactions.
If you want to customize the checkout experience while maintaining PCI compliance, it is recommended to use the iFrame payment form. This approach allows you to embed the payment form within your website using an iFrame, providing a seamless and secure payment experience for your customers while reducing your PCI compliance scope.
Enable Plug in
- Login to Virtual Terminal
- Navigate to Settings and click on "Plugin"
Trusted URL - In production, you should set the allowed URLs for the iFrame to ensure that it can only be activated from the intended websites. You can separate multiple domains using commas. Ex: https://www.yourdomain.com , https://subdomain.yourdomain.com
CSS -The Style Sheet URL field is used to specify the URL of the style sheet to be used for the payment form, if the style is based on the generic Nilon style sheet. If the payment form is enabled with overriding CSS while invoking, the style sheet specified here will be ignored.
Key - The key that will be generated by Nilon to be used as authentication key to authenticate the Iframe is a unique token that is used to verify the authenticity of the payment form and ensure that it is being accessed from a trusted source.
Account type- The account type checkboxes allow the merchant to select which payment options they want to offer to their customers. They can choose to display Credit Card or ACH or both as available payment options on the iFrame.
