# Segment

> Integrate Segment with your Mintlify documentation to route analytics events to downstream tools like warehouses, CRMs, and marketing platforms.

Add your Segment write key to your `docs.json` file to send analytics to Segment.

```json Analytics options in docs.json theme={null}
"integrations": {
    "segment": {
        "key": "required",
        "cdnUrl": "optional"
    }
}
```

```json Example theme={null}
"integrations": {
    "segment": {
        "key": "nqJxiRG15Y6M594P8Sb8ESEciU3VC2",
        "cdnUrl": "https://cdn.example.com"
    }
}
```

## Configuration options

- `key` (string, required) — Your Segment write key.

- `cdnUrl` (string) — A custom CDN URL for loading the Segment script. Use this if you configure a [custom domain](https://segment.com/docs/connections/custom-domain/) in Segment to serve analytics from your own subdomain, which helps avoid ad blockers that block `cdn.segment.com`. Must be an HTTPS URL without query parameters or fragments. Defaults to `https://cdn.segment.com`.
