Instantcart supports a number of payment modules such as Paypal, standing order, Sage Pay Server and Sage Pay Direct, however we recommend Paypal, as it's free and easy to setup. As Instantcart is a new service, if you have an account with a Payment provider that we currently do not list, just let us know, and our team will happily create a module to support it.
Step 1. Browse to your Instantcart Control Panel
Step 2. Activate your Payment Module
Click on the Edit option to activate your Payment Module if not already done so.
Click on the Merchant Accounts link to insert your Merchant settings. If using Paypal, we have a help topic on what details to put here.
