# Third-Party Integrations

> Configure email, error tracking, analytics, and external services for LangWatch

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

## Email (SendGrid)

Email is used for alerts, team invitations, and system notifications.

### Helm Configuration

```yaml theme={null}
app:
  email:
    enabled: true
    defaultFrom: "langwatch@yourcompany.com"
    provider: sendgrid
    providers:
      sendgrid:
        apiKey:
          secretKeyRef:
            name: langwatch-email
            key: sendgridApiKey
```

### Environment Variables

| Variable             | Description            |
| -------------------- | ---------------------- |
| `EMAIL_ENABLED`      | `true` to enable email |
| `EMAIL_PROVIDER`     | `sendgrid`             |
| `SENDGRID_API_KEY`   | Your SendGrid API key  |
| `EMAIL_DEFAULT_FROM` | Default sender address |

### Setup Steps

1. Create a [SendGrid account](https://sendgrid.com/) and generate an API key
2. Verify your sender domain in SendGrid
3. Configure the API key via the Helm chart or environment variable
4. Test by inviting a team member in the LangWatch UI

## Error Tracking (Sentry)

Capture application errors and exceptions for debugging.

### Configuration

| Variable     | Description                      |
| ------------ | -------------------------------- |
| `SENTRY_DSN` | Sentry DSN for the LangWatch app |

```yaml theme={null}
app:
  extraEnvs:
    - name: SENTRY_DSN
      value: "https://examplePublicKey@o0.ingest.sentry.io/0"
```

## 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

Used for jailbreak detection and content safety evaluators.

```yaml theme={null}
app:
  evaluators:
    azureOpenAI:
      enabled: true
      endpoint:
        secretKeyRef: { name: langwatch-evaluators, key: azureEndpoint }
      apiKey:
        secretKeyRef: { name: langwatch-evaluators, key: azureApiKey }
```

| Variable                          | Description               |
| --------------------------------- | ------------------------- |
| `AZURE_OPENAI_EVALUATOR_ENABLED`  | `true` to enable          |
| `AZURE_OPENAI_EVALUATOR_ENDPOINT` | Azure OpenAI endpoint URL |
| `AZURE_OPENAI_EVALUATOR_API_KEY`  | Azure OpenAI API key      |

### Google AI

Used for PII detection evaluators.

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

| Variable                   | Description                      |
| -------------------------- | -------------------------------- |
| `GOOGLE_EVALUATOR_ENABLED` | `true` to enable                 |
| `GOOGLE_CREDENTIALS_JSON`  | Service account credentials JSON |

<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.
</Note>

## 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](/self-hosting/configuration/backups) for ClickHouse cold storage and backup configuration
* [Environment Variables](/self-hosting/configuration/environment-variables#object-storage-s3) for S3 configuration reference
