Overview
Use this trigger to run specific actions when a task is marked complete. Assign next steps and notify the right people to keep projects on track and work moving.
TL;DR: The Task Completed trigger starts an automation the moment a task is checked off. You can react to finished work: assign the next step, notify your team, log the result, or start a follow-up automation to keep projects on track and work moving.

- Select a Project for the automation to monitor.
