# Third-Party Integrations

> Configure email, analytics, and external services for LangWatch

LangWatch integrates with several third-party services for notifications, storage, and evaluation capabilities.

## Email

Email carries alert notifications, scheduled reports, team invitations, usage warnings and password reset links. LangWatch sends through SMTP, AWS SES, SendGrid or Resend.

See [Email](https://langwatch.ai/docs/self-hosting/configuration/email.md) for choosing a gateway, the settings each one takes, and sending through an outbound proxy.

## Usage Analytics

LangWatch collects anonymous usage analytics by default to help improve the product. No trace data or PII is collected.

### Disable Telemetry

```yaml theme={null}
app:
  telemetry:
    usage:
      enabled: false
```

Or via environment variable:

| Variable | Description |
| - | - |
| `DISABLE_USAGE_STATS` | Set to `true` to disable anonymous usage analytics |

## LLM Providers for Evaluations

LangWatch evaluators use external LLM providers for model-based evaluations (LLM-as-a-Judge, safety checks, etc.). Configure these if you want to use built-in evaluators.

### Azure OpenAI

Configure Azure OpenAI for evaluators in **Settings > Model Providers**. The Helm chart has no value for it.

### Google Cloud DLP

Used for PII redaction of incoming traces.

```yaml theme={null}
app:
  evaluators:
    google:
      enabled: true
      credentials:
        secretKeyRef: { name: langwatch-evaluators, key: googleCredentials }
```

| Variable | Description |
| - | - |
| `GOOGLE_APPLICATION_CREDENTIALS` | The contents of a Google service account JSON key (the JSON itself, not a file path), with a `project_id`. Set on the app and workers when `app.evaluators.google.enabled` is on |

> [!NOTE]
>
> You don't need to configure evaluator providers to use LangWatch. They're only required if you
> want to use built-in evaluators that rely on specific LLM providers. You can always configure your
> own LLM provider API keys in the LangWatch UI for evaluations.

## Slack

LangWatch can send notifications to Slack channels via webhooks for alerts and automations. This is configured in the LangWatch UI under **Automations**, not via environment variables.

## S3, Object Storage

Used for dataset storage and ClickHouse cold storage/backups. See:

* [Backups](https://langwatch.ai/docs/self-hosting/configuration/backups.md) for ClickHouse cold storage and backup configuration
* [Environment Variables](https://langwatch.ai/docs/self-hosting/configuration/environment-variables.md#object-storage-s3) for S3 configuration reference
