Other languages logs installation

The key requirements are:

• Use OTLP (OpenTelemetry Protocol) for log export over HTTP
• Send logs to https://us.i.posthog.com/i/v1/logs (or your self-hosted endpoint)
• Include your project API key in the Authorization header or as a ?token= query parameter

Find the OpenTelemetry SDK for your language in the official registry.

You'll need your PostHog project API key to authenticate log requests. This is the same API key you use for capturing events and exceptions.

You can find your project API key in Project Settings.

Configure your OpenTelemetry SDK to send logs to PostHog:

• Endpoint: https://us.i.posthog.com/i/v1/logs
• Authentication: Include your project API key either:
  • In the Authorization header: Bearer {your-project-api-key}
  • As a query parameter: ?token={your-project-api-key}

Once everything is configured, test that logs are flowing into PostHog:

1. Send a test log from your application
2. Check the PostHog logs interface for your log entries
3. Verify the logs appear in your project
