title: SendGrid API: Get Campaign Stats
body: <p>I've been looking for a way to get SendGrid stats for specific campaigns. I can see the stats on the Campaigns page of the SendGrid dashboard, but I can't find an API endpoint to get that data.</p>
  <p>I could retrieve the Global and Overview stats, no problem, but in this case, those are not helpful for me. I need <em>per-campaign</em> stats. Is there a way to get those reports through the API?</p>
