17.11.1. Setup within Kartris
- Go to Configuration > Payment and Shipping Gateways and click to edit SagePay VSP Form.
- For the 'friendly name', enter the name you want this payment system to be referred to on the front of your site where customers select it, for example 'Pay by credit card with SagePay'.
- Change the status from 'OFF' to 'ON' (for live orders) or 'TEST' or 'FAKE' for testing. 'TEST' means that a test order will be passed, allowing you to test the full integration and pass multiple orders and no cost without needed to do refunds. 'FAKE' means that Kartris will skip the Opayo payment process and instead format a post back itself to the callback page of Kartris. This is useful for testing that the callback process works, triggers the appropriate emails and so on without keep having to keep going through the Opayo test payment process.
- ProcessCurrency - if your store supports some currencies that your Opayo account cannot process, you should set this with a three-letter ISO code to convert all orders to this currency prior to sending users to the payment pages.
- Test URL - (for test orders) should be:
https://sandbox.opayo.eu.elavon.com/gateway/service/vspform-register.vsp - Post URL - (for live orders) should be:
https://live.opayo.eu.elavon.com/gateway/service/vspform-register.vsp - VSPProtocol - Opayo uses a versioning system so that when a newer version of their system is introduced, you can continue to process orders with the older version (at least for some period). The Kartris Opayo support is designed for 'Protocol 3.00', so you should not change this number unless your Kartris payment system is upgraded at some point in the future.
- The other various Opayo settings required should be supplied to you by Opayo.
