title: Paypal Button Code to Auto Redirect after payment
body: <p>In my paypal button, I have the return and cancel_return variable with their urls. When a payment is complete and a user wants to return to the site, they will have to click the link. </p>
  
  <p>I read in different places that for me to enable auto redirect, I will need to go to Profile, Website Payments Payments Preferences, Auto Return.</p>
  
  <p>The problem is that when I go to Profile, I cannot find Website Payments Payments Preferences, so I would like to find out how this can be done programmatically on the button.</p>
  
  <p>Appreciate it.</p>
