What payment gateways does Return Magic support with Shopify?

Certain payment gateways don't allow for refunds, meaning you will get an "Payment was not captured" error in the app. Return Magic will not be able to refund your customers automatically, but you can mark a return as manually refunded and process it yourself.

Here is a list of payment gateways that we know for sure the app supports.
Note that it is not an exhaustive list, and new payment gateways might still work.
