Azure Event Grid is a fully managed event routing service from Microsoft Azure that enables event-driven, reactive programming by ingesting events from Azure services, SaaS providers, and custom sources and delivering them to subscribers such as Azure Functions, Logic Apps, webhooks, and event hubs. It supports both Event Grid topics and the MQTT/CloudEvents-based Event Grid namespaces for IoT and pub-sub workloads. The Event Grid REST APIs and Azure SDKs use Microsoft Entra ID OAuth 2.0 bearer tokens or shared-access keys for authentication.
