Similar to the variables that we can save from the response of 'Ask A Question' step, trigger variables are the readily available variables to be used in the Workflow if a specific trigger is selected.
Trigger variable for "Conversation Closed" trigger:
  1. $conversation.opened_time
  2. $conversation.closed_time
  3. $conversation.closed_by
  4. $conversation.closed_by_source
  5. $conversation.first_response_time
  6. $conversation.resolution_time
  7. $conversation.incoming_messages_count
  8. $conversation.outgoing_messages_count
  9. $conversation.category
  10. $conversation.summary
  11. $conversation.assignee
  12. $conversation.assignee_team
The trigger variables above would be very useful in combination with "HTTP Request" Workflows Step to send relevant information to your data warehouse especially for CSAT purposes.
We welcome any constructive feedback or suggestions on the variables.
