I am a Hong Kong Shopify user and there is only Paypal Payment Pro Hosted Solution here. As Shopify does not support this, we have do a manual integration. And Shopify API does not allow order creation at the moment, so I guess I can have Paypal sends an IPN to Shopify and Shopify will handle the rest?
If so, what is Shopify Paypal IPN handler URL? I had searched on the net and found nothing. Please help. Thanks!
