title: Paypal Get Subscription Details
body: <p>My website is using subscriptions payments and the old programmer did not used ipn, to activate the account he used a custom return url (ya, very stupid).</p>
  
  <p>The issue here, is that old subscription does not have any custom information attached to the ipn (new subscriptions are ok).</p>
  
  <p>Is there a way to find out the return url used in the initial payment?</p>
  
  <p>Thanks</p>
