We've identified the cause of this issue to be an unannounced change in PayPal's refund API data validation, resulting in their API no longer accepting refund requests with our pre-generated refund reason.

A change to better handle the refund reason has been deployed, and it should be possible to process refunds as expected again.

Today we've seen an increase in errors from PayPal when attempting to refund certain transactions, starting with refunds attempted this morning. This appears to only affect refunds from payments using the PayPal REST APIs and is presenting itself in a similar way to a PayPal incident on Friday available at

While we continue to investigate this, it is still possible to refund payments via the PayPal Manager and we'd suggest doing so until this issue is resolved.
