Integrate Azure Event Hubs with Service Connector

This page shows the supported authentication types and client types of Azure Event Hubs using Service Connector. You might still be able to connect to Event Hubs in other programming languages without using Service Connector. This page also shows default environment variable names and values or Spring Boot configuration you get when you create service connections. You can learn more about the Service Connector environment variable naming convention.
