As mentioned in https://nopcommerce.codeplex.com/workitem/10512
PayPal IPN does not properly support recurring payment. This work item is still on roadmap. So currently, the order/payment status change with the IPN notification if it is a one time charge but not if it’s a recurring payment. I want to implement it so that it also supports for recurring payments. can anyone tell me how can i achieve that? what i would need to implement it?
