title: Testing Paypal subscription IPN
body: <p>I'd like to test paypal subscription IPNs, both the ones received when a subscription is created, and the ones sent later with the next payment (such as monthly if the subscription is $x per month).</p>
  
  <p>However I'd prefer not to wait a month or a day to receive the second IPN. Is there a way to have an IPN sent quicker, such as hourly, using paypal or their sandbox?</p>
  
  <p>On the documentation it says you can only specify years, months, days, and weeks as the subscription period.</p>
