How to initiate a refund?

Refunds can be processed in three ways:

1. During cancellation: Click "Cancel subscription" and then select "no refund / full refund / prorated refund" in the subscription details; the system will trigger and update the invoice automatically.
2. Non-cancellation scenario: Click “Refund” in the relevant trade order; the system will generate a refund order and sync with the payment channel.
3. Via OpenAPI: Initiate a refund programmatically using our API.
