Trello Trigger

Run your program when changes are made to your Trello boards, lists, and cards.
To get data from Trello or automate creating new cards, use the Trello module.
​ Link Your Trello Account
When you add a Trello Trigger to your program, you will be prompted to link an account if you have not done so already. 
​ Event Types
Choose when you would like the trigger to run:
When one of my boards changes

When a specific card changes
If the trigger is set to run "when a specific card changes," you will be able to select one of the 1000 most-recent cards on your Trello board.
