Zapier
Zapier lets you connect Apptoto to other web services through automated workflows called Zaps. A Zap consists of a trigger (an event in one app) and one or more actions (things that happen in another app as a result).
Apptoto supports both directions: Apptoto can trigger actions in other apps, and other apps can trigger actions in Apptoto.
