分享 The Instant Payment Notification (IPN) of paypal calls a script on your server and transmit all payment information as $_POST-variables.
You have to give the user an unique hashid and send it along by redirecting the user to paypal. The user pays your products and after a successful payment he can return to your merchant and your script is called by paypal.
Here you can create your own script for IPN: https://www.paypaltech.com/SG2/
You will be notified after a successful payment. It's not relevant whether the user returns to your merchant or not.
