# Click a button

**Click a button** is a **Manual trigger**.

It starts the workflow only when someone clicks **Run**.

This trigger does **not** collect or send any input.

## When to use it

* When you want to run a workflow on demand.
* When the workflow does not need form fields, chat input, or external data.
* When you want a simple trigger for internal tools or quick manual tasks.

## How it works

1. Add a **Trigger** node.
2. Choose **Click a button** as the type.
3. Click **Run** to start the workflow.

That’s it. The workflow starts immediately, with no input payload.

## Good to know

Diaflow groups triggers into **Automatic trigger** and **Manual trigger**.

**Click a button** belongs to **Manual trigger** and is the simplest way to start a workflow by hand.
