Integrating Dialogtrail with Rule
Rule has a very good connection for Facbook dialogues via Dialogtrail
Sign in to Rule and go to the developer page https://app.rule.io/#/settings/developer
Click "New API Key". The API key is a security task, so treat it gently, much like a password.
Click "Copy". Now you have the API key in your computer's clipboard (ClipBook Viewer).
Now you're done in Rule!
