How i can get PaymentId associated with a refund using API?
for example, i can get this using builtin callback Payment Refund Processed

But i can't found a way for getting PaymentId using a similar custom callback or REST\SOAP API.
Do you have any idea how i can get paymentId by RefundId without "Invoice Settlement feature"?
Try using refund parts API call as shown below. ../v1/refunds/{refundId}/parts
