Automations: when this happens, do that — Pick a trigger
Open Automations from Manage workspace at the foot of the rail and press New automation. Choose when it fires: a record is created, updated (optionally only when specific fields change), deleted, matches conditions, on a schedule, or a webhook is received.
Matches conditions is the “status becomes Done” trigger: it fires only when a record enters the matching state — editing a record that already matches won't re-fire it.
Schedules run every N minutes (5 minimum), daily, or weekly at a UTC time. With a table chosen, the schedule runs once per record matching your conditions (up to 100 per fire); without one it runs once per fire.
Every automation is these three parts. Leaving the middle one empty means it runs every time.
