Third-Party Integrations

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 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

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.

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.

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

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 for ClickHouse cold storage and backup configuration
