# set_trigger

> Create an outbound event trigger (a webhook) so an external tool is notified when something happens in the workspace — a new contact, a reply, a meeting booked.

Wire the user's stack to fire when the record changes. Pass the destination URL and which events to fire on. Call [`list_triggers`](/mcp/tools/list-triggers) first to see the catalog of available event names.

## Parameters

| Name     | Type      | Required | Description                                                   |
| -------- | --------- | -------- | ------------------------------------------------------------- |
| `url`    | string    | yes      | The destination URL the event is POSTed to.                   |
| `events` | string\[] | yes      | Event names to fire on (see `list_triggers` for the catalog). |
| `name`   | string    |          | Optional label for the trigger.                               |

## Returns

```
Trigger created for interaction.email_received → https://hooks.example.com/nous.
```

## When to call it

* When the user wants an external tool (n8n, a Slack relay, their own service) notified on a workspace event.
* After `list_triggers` so you use valid event names.
