Refunds
Refund an order in Tringify as usual, in full or in part. The refund goes to the Paystack payment and always uses the account that took it. If Paystack does not confirm a refund, Tringify never sends it twice: check it in the Paystack dashboard.
Making a refund
Open the order in Tringify and choose Refund. Pick the items or amount; Tringify sends the refund to Paystack through the app. The order's Refunds section shows it as Processing until Paystack confirms it, then Refunded, or Failed with Paystack's reason. You don't need to do anything in Paystack.
A refund always goes back to the payment it refunds and uses the Paystack account that took that payment, even if you have since changed keys or disconnected.
