Workflow automation vocabulary quick reference
- Trigger — the event that starts a flow; types: event, scheduled, manual, webhook
- Action — a step that performs an operation (send email, create record, call API)
- Connector — a pre-built integration wrapper for a specific service, handling auth and API calls
- Condition — an if/else branching control based on a boolean expression
- Human-in-the-loop — a workflow pause waiting for a human decision (approval step)
- Error handler — a scope that executes when a step fails; captures and notifies on errors
- Idempotent — produces the same result regardless of how many times it runs with the same input

A business analyst is designing a Power Automate flow. They ask: "What exactly is a trigger, and what are the main types I need to know?"
Triggers are the foundational concept in all workflow automation platforms — choosing the wrong trigger type is one of the most common design mistakes in flow development.
The four main trigger types:
Trigger selection implications:
• Event triggers run immediately on the event — best for real-time automation
• Scheduled triggers include a built-in delay; avoid for time-sensitive processes
• Webhook triggers enable external systems to start Power Automate flows — the most powerful integration pattern
• Manual triggers bypass automation entirely — useful for user-on-demand processes or testing
Key vocabulary:
• Trigger — the event that starts a workflow execution
• Webhook — an HTTP callback that allows external systems to push events to a workflow
• Recurrence trigger — a scheduled trigger that fires at a defined interval or specific time
• Polling trigger — a trigger that periodically checks for new events (e.g. checks for new emails every minute)
The four main trigger types:
| Trigger type | When it fires | Power Automate example |
|---|---|---|
| Event | When a specific event occurs | "When a new item is added to SharePoint" |
| Scheduled | At a fixed time or interval | "Recurrence: every Monday at 8am" |
| Manual | When a user initiates it | "Manually trigger a flow" / button in Power Apps |
| Webhook / HTTP | When an HTTP POST arrives | "When an HTTP request is received" |
