Custom Field Variables
The value of custom fields can be obtained by using a variable in the form {{%Field Name}}
.
Examples:
when custom field "Start Date" is set by anyone, post comment "The Start Date custom field was set to: {{%Start Date}}"
when a card is moved to list "Done" by anyone, add member @{{%Tester}} to the card, and post comment "@card Task with priority {{%Priority}} was completed and is ready for testing.",
