Refunded a customer via PayPal and not through Shopify itself

[kkanee]

Hello,

I have just had a customer that ordered paying on PayPal. I have refunded them due to stock issues, however, I refunded them directly through PayPal and not via Shopify refunds. Therefore, on Shopify, it does not show that I have refunded them.

How do I process this refund through Shopify without refunding them twice?

I hope that makes sense!

Thank you!
