Plain definition: A trigger is the specific event that starts an automated workflow. When the trigger condition is met, the automation begins — no human needs to start it manually.

In plain terms

A trigger is the “if” in an “if–then” rule. Motion-sensor lights are a simple example: the trigger is movement detected, the action is the light turning on. In business automation, the trigger might be a form submission, a new row in a spreadsheet, a payment received, or a specific time of day. The trigger is what sets everything in motion.

Why it matters for operators

Every automation has a trigger, so understanding triggers is the first step to building any automated process. Choosing the right trigger determines when your automation fires and whether it runs reliably. Common triggers in business tools include: a new contact is added, an order is marked shipped, an invoice becomes overdue, or a calendar event starts. Most no-code platforms list available triggers clearly for each connected app.

Example

A property management company sets the trigger “lease end date is 90 days away.” When that condition is met for any tenant, the automation sends a renewal offer email automatically — no one needs to remember to check a spreadsheet.
