title: Paypal integration
body: <p>I am facing a problem with paypal integration. From my site I want the user to go to PayPal's site after selecting their product. But once the user makes a payment they do not return to my site so their order is not saved in my site but payment id going through to paypal.
  I am using php to integrate.</p>
  
  <p>Can anyone help me fix this?</p>
