Custom payment url for Xero accounting system

We are using [login to view URL] for accounting system, we want to add a custom payment gateway via [login to view URL] A custom URL is designed for payment services that Xero does not officially integrate with. This URL should contain placeholders that will be replaced with relevant invoice data. These placeholders are [INVOICENUMBER], [CURRENCY], [AMOUNTDUE] & [SHORTCODE]. An example URL might look like: Eg : [login to view URL][INVOICENUMBER]&currency=[CURRENCY]&amount=[AMOUNTDUE]&shortCode=[SHORTCODE] We are going to use cybersource as the payment-gateway provider you can use any of below SDK for integration.
