Apologies for the confusion; we need to access the Azure Service Bus from Microsoft Fabric only i.e. have to push the message to Azure Service Bus from Microsoft Fabric.

Hi RajeshKapur 
To access Azure Service Bus behind a private endpoint from Microsoft Fabric, follow below steps:

​Configure Azure Service Bus with a Private Endpoint.

Grant Network Access to Fabric

• Make sure Fabric's managed identity or azure function (if used) has network access to Service Bus.
• Use Azure private link or VNet integration.

Use a Fabric Notebook:

• Install dependencies:
   !pip install azure-servicebus
• Connect and send a message:

****************************************************
from azure.servicebus import ServiceBusClient, ServiceBusMessage

CONNECTION_STR = "your_private_endpoint_connection_string"

QUEUE_NAME = "your-queue"

with ServiceBusClient.from_connection_string(CONNECTION_STR) as client:

    with client.get_queue_sender(QUEUE_NAME) as sender:

        sender.send_messages(ServiceBusMessage("Message from Fabric"))

        print("Message sent successfully!")

Hi RajeshKapur 
Sorry for the misunderstanding the limitations. After a through research found the direct access to Azure Service Bus via private endpoints from Fabric Notebooks is not supported at this time.
Managed private endpoints in Fabric currently support data sources such as Azure Storage and Azure SQL Database, but not Azure Service Bus.

While direct notebook access is limited, Fabric's Event Streams feature allows integration with Azure Service Bus. This setup enables messages from the Service Bus to be fetched into Fabric's event stream and routed to various destinations within Fabric.

Do we have any documentation around. The steps mentioned above doesn't seems to be working. Reason is Azure Service Bus is behind Private End Point.

Hi RajeshKapur 

Thanks for reaching out to the Fabric Community.

• Currently, Microsoft Fabric Eventstream cannot connect to Azure Service Bus secured with a private endpoint, as Fabric does not support VNet integration or managed private endpoints for Eventstream.

• Service Bus private endpoints only allow access from within your Azure VNet; Fabric’s managed SaaS environment is outside your private network.

• The official Microsoft documentation states that to access a Service Bus namespace over a private endpoint, the consuming resource (application or service) must also be in the same VNet or peered VNet, or be able to route through the private network.

• As a workaround, temporarily enable public access to Service Bus if permitted, or use an intermediary (such as Azure Functions or Logic Apps in your VNet) to relay messages from Service Bus to Fabric.
