The record is not found

A pending refund of the same amount without a payment processor reference already exists for the transaction: the payment processor has not yet accepted it, or accepted it without returning a refund reference. Wait for that refund to be finalized or to fail before requesting the same amount again.

A pending refund that already has a payment processor reference does not block a request for the same amount; such a request is accepted if the remaining refundable amount allows it.

The transaction cannot be refunded. The message states the reason:

• the transaction is not finalized
• the payment processor of the transaction does not support refunds, or refunds are disabled for it
• the transaction is older than the refund period the payment processor allows
• the transaction was paid by bank transfer
• the transaction has no payment processor reference
• the transaction has no remaining amount to refund

The payload you provided is invalid

The payment processor rejected the refund request, or did not answer it (for example, a timeout). The refund is recorded with status failed and its failure reason, readable through transactionRefundId.

When the payment processor did not answer, it may still have processed the refund. Its notification then records that refund as a separate refund on the same transaction. Do not retry blindly: before requesting another refund, check the transaction's refunds through the transaction refunds resource (filter[transactionId]) or the transaction's refundedAmount.
