Event Hubs Recipe

Event Hubs streaming trigger with managed identity authentication.

Template Selection

Resource filter: eventhub Discover templates via MCP or CDN manifest where resource == "eventhub" and language matches user request.

Troubleshooting

"Unauthorized" or "Forbidden" Errors

Cause: Missing UAMI credential settings for Event Hubs. Solution: Ensure all three settings are present in app configuration:

• EventHubConnection__fullyQualifiedNamespace
• EventHubConnection__credential (value: managedidentity)
• EventHubConnection__clientId

See Event Hubs trigger connections for identity-based config — refer to the "Connections" section on that page for managed identity app settings.

Events Not Arriving

Cause: Consumer group or checkpoint storage misconfigured. Solution: Verify the Event Hubs consumer group exists and the function has Azure Event Hubs Data Receiver role on the namespace.
