Azure Event Hubs Management API

Managing Event Hubs with the Management API

The Azure Event Hubs Management API allows you to programmatically create, update, delete, and query Event Hubs namespaces, Event Hubs, and consumer groups. This is crucial for automating infrastructure management, integrating with CI/CD pipelines, and building dynamic solutions.

Overview

The Management API is a RESTful API that uses standard HTTP methods (GET, PUT, POST, DELETE) and JSON for request and response bodies. It's designed to interact with Azure Resource Manager (ARM), enabling you to manage Event Hubs resources within your Azure subscriptions.

Authentication

Access to the Management API is secured using Azure Active Directory (Azure AD). You'll need to obtain an OAuth 2.0 access token to authenticate your requests. Typically, this involves:

• Registering an application in Azure AD.
• Granting the application appropriate permissions (e.g., "Azure Event Hubs Data Owner" or custom roles) to manage Event Hubs resources.
• Using a client ID, client secret, or certificate to acquire an access token.

All API requests must include an Authorization header with the obtained Bearer token:

Authorization: Bearer 

Key Resources and Operations

Event Hubs Namespaces

Namespaces are the fundamental containers for Event Hubs. The API allows you to manage them within your resource groups.

• Create Namespace: PUT /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}
• Get Namespace: GET /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}
• List Namespaces: GET /subscriptions/{subscriptionId}/providers/Microsoft.EventHub/namespaces
• Delete Namespace: DELETE /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}

Event Hubs

Event Hubs are created within a namespace and are the actual conduits for streaming data.

• Create Event Hub: PUT /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}/eventhubs/{eventHubName}
• Get Event Hub: GET /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}/eventhubs/{eventHubName}
• List Event Hubs: GET /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}/eventhubs
• Delete Event Hub: DELETE /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}/eventhubs/{eventHubName}

Consumer Groups

Consumer groups allow multiple applications or services to read from an Event Hub independently.

• Create Consumer Group: PUT /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}/eventhubs/{eventHubName}/consumergroups/{consumerGroupName}
• Get Consumer Group: GET /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}/eventhubs/{eventHubName}/consumergroups/{consumerGroupName}
• List Consumer Groups: GET /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}/eventhubs/{eventHubName}/consumergroups
• Delete Consumer Group: DELETE /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}/eventhubs/{eventHubName}/consumergroups/{consumerGroupName}

Example Request: Creating an Event Hub

This example demonstrates how to create a new Event Hub named my-event-hub within a namespace my-namespace in a specific resource group and subscription.

Request URL:

PUT https://management.azure.com/subscriptions/YOUR_SUBSCRIPTION_ID/resourceGroups/YOUR_RESOURCE_GROUP/providers/Microsoft.EventHub/namespaces/my-namespace/eventhubs/my-event-hub?api-version=2021-11-01

Request Headers:

Content-Type: application/json
Authorization: Bearer YOUR_ACCESS_TOKEN

Request Body:

{
  "properties": {
    "messageRetentionInDays": 7,
    "partitionCount": 4
  }
}

Error Handling

The Management API follows standard HTTP error codes. Common status codes include:

Error responses typically contain a JSON body with details about the error, including an error code and a message.

Best Practices

• Use the latest API version: Always refer to the official Azure Event Hubs Management API documentation for the most up-to-date API versions and details.
• Idempotency: Design your automation scripts to be idempotent. PUT operations, for example, should be safe to run multiple times.
• Error Handling: Implement robust error handling in your code to gracefully manage API failures and retries.
• Least Privilege: Grant only the necessary permissions to your Azure AD application.
• Version Control: Store your API interaction scripts and ARM templates in version control.

By leveraging the Event Hubs Management API, you can build highly automated and scalable solutions for managing your event streaming infrastructure.
