Power Automate Trigger Types ⚡

A trigger is the event that starts a cloud flow. Every flow has exactly one trigger, and choosing the right kind, automated, instant or scheduled, decides how and when your automation runs.

TL;DR: Automated flows start when an event happens (a new email, a new SharePoint item). Instant flows start on demand, you tap a button or run them from an app. Scheduled flows start on a clock, at set times or intervals. Pick the trigger that matches what makes the work need to happen.

The three cloud flow trigger types

Trigger type	Starts when	Example
Automated	An event occurs	New SharePoint item arrives
Instant (manual)	You run it on demand	Tap a button to start it
Scheduled	A clock/recurrence fires	Send a daily report

Automated triggers

🔸 Automated flows are initiated automatically based on an event or condition, for example “When a new email arrives” or “When an item is created”.

🔸 Most connectors expose prebuilt triggers (Outlook, SharePoint, Dataverse, Teams). This is the workhorse pattern: something changes, and the flow reacts.

🔸 Use this when the work should happen the moment an event occurs, with no human kicking it off.

Instant (manual) triggers

🔸 Instant flows are started on demand, with a tap of a button on your mobile device, a button in an app, or the “manually trigger a flow” trigger.

🔸 They’re good for human-in-the-loop actions: a user decides now is the time, for example to start an approval, send a reminder or trigger a task.

🔸 Instant flows can also be called from a Power App or another flow, passing in parameters.

Scheduled triggers

🔸 Scheduled flows run on a schedule, at a specific time, or on a repeating interval such as every hour, daily or weekly.

🔸 Use these for recurring, time-based work: nightly data syncs, daily digest emails, periodic clean-up jobs.

🔸 The schedule is defined on the Recurrence trigger (interval plus frequency, with an optional start time).

How to choose

🔸 “When X happens, do Y” points to Automated.

🔸 “When I (or a user) decide, do Y” points to Instant.

🔸 “Every day/hour, do Y” points to Scheduled.

🔸 Beyond cloud flows, desktop flows (RPA) can also be started manually, by a cloud flow, or on a schedule; see the flow-types guide.

⚠️ Watch out

🔸 A flow has exactly one trigger. If you need several entry points, use child flows or an instant flow that other flows call.

🔸 Automated triggers can fire a lot. High-volume event sources mean many runs, so add trigger conditions/filters so the flow only runs when it truly should.

🔸 Scheduled isn’t real-time. A recurrence that runs hourly can lag events by up to an hour; use an automated trigger when you need immediacy.

🛠️ FAQ

What’s the difference between automated and instant? Automated flows start by themselves when an event occurs; instant flows start because a person runs them (button, app, manual trigger).

Which trigger sends a daily report? A scheduled (Recurrence) trigger set to run once a day.

Can one flow have multiple triggers? No, each cloud flow has a single trigger. Split logic into child flows or an instant flow that others call.

How do I stop an automated flow running too often? Add trigger conditions (or filter columns) so the flow only starts for the rows/events you care about.
