  title: New Relic Log Logs API
  description: The New Relic Log API enables log data to be sent directly to the New Relic platform via HTTP POST requests. It accepts gzip-compressed JSON payloads and provides an alternative to log forwarding agents when direct integration is preferred. Logs are available for querying in New Relic Logs UI and via NRQL immediately after ingestion.
