Azure Event Grid Management Client Library

Warnings

• breaking Azure SDK for Python libraries (Track 2) often introduce breaking changes between major versions. These changes typically align with updates to the underlying Azure REST APIs or the SDK guidelines, affecting resource models, method signatures, or parameter names. Always review release notes when upgrading to a new major version.
  Fix: Consult the official migration guide and release notes for the specific library version. Update your code to reflect new model structures or method signatures.
• gotcha Resource provisioning in Azure (like creating an Event Grid topic or domain) can be an asynchronous operation. Chaining dependent operations too quickly after a create/update call might result in 'resource not found' or 'resource not ready' errors due to eventual consistency.
  Fix: Implement polling mechanisms or introduce delays to wait for resources to reach a stable `succeeded` provisioning state before attempting subsequent operations. The Azure SDK may provide `begin_create_or_update` methods that return long-running operation pollers.
• gotcha The `azure-mgmt-eventgrid` library manages Event Grid resources. For publishing or consuming events, you need `azure-eventgrid` (the data plane SDK), which is a separate library with different imports and client objects.
  Fix: Ensure you are using the correct library for your task: `azure-mgmt-eventgrid` for resource management (create, update, delete topics/domains) and `azure-eventgrid` for data plane operations (send/receive events).
• gotcha Authentication with Azure services locally requires setting up `DefaultAzureCredential` correctly. Common issues include not being logged in via `az login` (Azure CLI) or missing required environment variables for service principal authentication (`AZURE_CLIENT_ID`, `AZURE_TENANT_ID`, `AZURE_CLIENT_SECRET`).
  Fix: For local development, ensure you've run `az login` or configured the necessary environment variables for your chosen credential type. For production, consider Managed Identities for Azure resources.

Install

• pip install azure-mgmt-eventgrid Install stable version

Imports

• EventGridManagementClient

  from azure.mgmt.eventgrid import EventGridManagementClient

• DefaultAzureCredential

  from azure.identity import DefaultAzureCredential

  Required for authenticating with Azure services. Install separately with `pip install azure-identity`.

Quickstart

This quickstart demonstrates how to authenticate with Azure using `DefaultAzureCredential` and then list all Event Grid topics within a specified Azure subscription using the `EventGridManagementClient`. Ensure you have the `AZURE_SUBSCRIPTION_ID` environment variable set and have appropriate permissions in Azure.

import os
from azure.identity import DefaultAzureCredential
from azure.mgmt.eventgrid import EventGridManagementClient

# Set your Azure Subscription ID as an environment variable or replace directly
# Example: export AZURE_SUBSCRIPTION_ID="<your-subscription-id>"
subscription_id = os.environ.get("AZURE_SUBSCRIPTION_ID", "")

if not subscription_id:
    raise ValueError("AZURE_SUBSCRIPTION_ID environment variable not set.")

# Acquire a credential object using DefaultAzureCredential
# This will attempt to authenticate via various methods:
# Environment variables, Managed Identity, Azure CLI, VS Code, etc.
# For local development, ensure you are logged in via Azure CLI (`az login`)
credential = DefaultAzureCredential()

# Create the Event Grid Management Client
client = EventGridManagementClient(credential, subscription_id)

print(f"Listing Event Grid topics in subscription: {subscription_id}")

try:
    # List all Event Grid topics in the subscription
    topics = client.topics.list_by_subscription()
    for topic in topics:
        print(f"- Topic Name: {topic.name}, Location: {topic.location}")
except Exception as e:
    print(f"An error occurred: {e}")
    print("Ensure you have 'Contributor' or 'Owner' role on the subscription.")
