I would like to know how to check if PayPal is working properly on my site

[ninja3]

PayPal and Shopify are linked, and I am using the sendowl app as I sell product keys. It is scheduled to open soon, but it is impossible to check whether PayPal payment is accepted in Korea. I would really appreciate it if you could tell me how to check this... Even PayPal and Shopify say it is difficult to confirm.
