Integrate Apache Kafka on Confluent Cloud with Service Connector

This page shows the supported authentication types and client types of Apache kafka on Confluent Cloud with Service using Service Connector. You might still be able to connect to Apache kafka on Confluent Cloud 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 the service connection. You can learn more about Service Connector environment variable naming convention.

Supported compute services

• Azure App Service
• Azure Container Apps
• Azure Spring Apps

Supported Authentication types and client types

Supported authentication and clients for App Service, Container Apps and Azure Spring Apps:

Client type	System-assigned managed identity	User-assigned managed identity	Secret / connection string	Service principal
.NET
Java

Node.js
Python
None

Default environment variable names or application properties

Use the connection details below to connect compute services to Kafka. For each example below, replace the placeholder texts <server-name>, <Bootstrap-server-key>, <Bootstrap-server-secret>, <schema-registry-key>, and <schema-registry-secret> with your server name, Bootstrap server key, Bootstrap server secret, schema registry key, and schema registry secret.
