title: Edit Database After Successful paypal payment
body: <p>I've been at this for a bit now, and I have tried using google extensively.</p>
  
  <p>I have my application set up: it is a HWID System available only to paid subscribers.</p>
  
  <p>I want buyers to be able to click on a 'buy now button', and once they successfully pay it automatically adds their information into the database the app uses. This way there is no waiting after payments.</p>
  
  <p>I know this is possible, because I've seen it done before - I just can't seem to find how it works?</p>
  
  <p>I would prefer this be done in php as well.</p>
