  title: Azure Event Hubs Data Plane REST Authorization Rules Disaster Recovery Configs API
  description: The Azure Event Hubs Data Plane REST API enables you to send events to and interact with Event Hubs directly. This API operates against the Event Hubs service endpoint at {namespace}.servicebus.windows.net and supports sending individual events, batch events, partition-specific events, and events with publisher identity. Authentication is via Azure Active Directory tokens or Shared Access Signature (SAS) tokens.
