Checkout for Payment with Terms and Conditions

The payment gateway allows you to use an iFrame to embed the payment and terms and condition details into your web site.

📘

Using the iFrame mode requires the merchant website to use the HTTPS protocol on all of its pages to ensure secure communication between the merchant's website and the OnePay gateway.

If you wish to implement a custom checkout experience while still limiting your PCI compliance, the recommended approach is to use the iFrame payment form.

Enable Plug in

• Login to Virtual Terminal
• Navigate to Settings and click on Plug in

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 OnePay 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 OnePay 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.
