# Event triggers

> The agent reacts to events in your services — new emails, meetings, files.

A **trigger** is a condition that, when it occurs, makes the agent run a defined action. Unlike a schedule, a trigger isn't tied to time — it fires the moment an event happens.

## Available triggers

| Service             | Event                 |
| ------------------- | --------------------- |
| **Gmail**           | New incoming email    |
| **Google Calendar** | Event created         |
| **Google Calendar** | Event changed         |
| **Google Calendar** | Event deleted         |
| **Google Drive**    | New file added        |
| **Google Drive**    | Existing file changed |

## How to create a trigger

Describe the condition and reaction in chat:

```text theme={null}
When a new email arrives in Gmail, check if it needs a reply,
and if yes — draft one and send to me for approval in Telegram.
```

## Credit usage

<Warning>
  Triggers consume integration credits on every fire. If your inbox is busy, a per-email trigger can burn credits much faster than a scheduled task.
</Warning>

## Trigger + schedule example

* **Trigger** on emails from VIPs → instant Telegram alert
* **Schedule** at 8:00 → summary of everything else overnight
