Refunds
Refund an order in Tringify as usual. The refund goes to the Square payment and Square returns the money to the shopper’s card. Refunds always use the token that took the payment, even after you change it or disconnect.
Making a refund
Open the order in Tringify and choose Refund. Pick the items or amount; Tringify sends the refund to Square through the app. The order's Refunds section shows it as Processing until Square confirms it, then Refunded, or Failed with Square's reason. You don't need to do anything in Square.
A refund always goes back to the payment it refunds and uses the Square account that took that payment, even if you have since changed keys or disconnected.
