I shipped the wrong parts to a buyer and trying to issue a refund for the cost
of the parts he paid for. A mix up between two orders, so I can't replace.
But I'm getting a PayPal processing error.
Admittedly it's for GBP 0.31 which might be below a PayPal limit, could that
be it?
There's no minimum, you can refund 0.01 (but below IDK).
What's the error?
Be sure to have a simple text in the refund, avoid weird chars or punctuation...
Try with no text at all.
Check if you've enough of this currency in your PayPal account.
Check also on PayPal if it's not already refunded; it happened to me I refunded
twice after the first was said "error" but was processed on PayPal anyway...
