I am trying to design a web application(using php and mysql) in which I will ask my clients to pay via paypal subscription, which detects money from the clients paypal account automatically and transfers it to my paypal account.
Now when a client logs into my web application after 3 months of time, is there a way my web application to know if a payment has been made from the clients account to my merchant account in the last 30 days.
Any suggestions please
