What Are Trigger Steps?

Trigger steps initiate workflows based on specific events or conditions. They serve as the starting point of your workflow, activating when certain events occur.

​
Types of Trigger Steps

There are many types of triggers available:
  • Slack: On send message, On reply
  • Gmail: On receive email, On send email
  • Google: Sheets, Calendar, Drive
  • Notion: Database and page triggers
  • And many more…
We’re constantly expanding our integration ecosystem, with new services and capabilities being added on a regular basis to help you build more powerful workflows.

​
Identifying Trigger Steps

In the step selection modal, trigger steps are marked with a green zap icon overlay on the integration logo, making them easy to identify.

​
How Trigger Steps Work

As the starting point of your workflow, trigger steps:
  • Cannot have incoming step connections
  • Execute all connected steps when their triggering event occurs
  • Pass event data to connected steps

​
What Are Action Steps?

Action steps interact with external services to perform specific operations. They complement trigger steps by enabling your workflow to not only respond to events but also take actions in various systems. Examples of action steps include:
  • Sending emails
  • Posting Slack messages
  • Creating Google Calendar events
  • Updating spreadsheet data
  • Creating content in Notion

​
Building an Automated Email Reply System

Let’s look at a practical example of how trigger and action steps work together:
  1. An “On Received Email” trigger step detects new incoming emails
  2. A Model step processes the email content and generates an appropriate reply
  3. A “Send Email” action step sends the generated reply back to the sender
Email reply workflow With just these three steps, you’ve created a complete automated email reply system. You could further enhance this workflow by adding a “Send Slack Message” action to notify your team when new emails arrive, including details like subject, body, and sender information.
