  title: New Relic Event Alerts Transactions API
  description: The New Relic Event API allows you to send custom event data to the New Relic platform via HTTP POST. Custom events submitted through this API can be queried and visualized using NRQL, making it suitable for tracking arbitrary business or application events. Each event is a JSON object with an eventType and any number of additional attribute key-value pairs.
