Track Heroku deploys in SpeedCurve
Push this button 
Finally, go to any other Heroku app for which you wish to notify SpeedCurve when they're deployed, and add an HTTP deploy hook pointing to https://[URL]/deploy/[your SpeedCurve API key], where [URL] is the URL of the Heroku app you just created, like so:
heroku addons:add deployhooks:http --url=https://your-speedcurve-heroku-app.herokuapp.com/deploy/abc123whateverSpeedCurve will get notified whenever the app is deployed, and start a batch of tests.
