How to create a WebPubSubServiceClient with Python and Azure Identity

This how-to guide shows you how to create a WebPubSubServiceClient using Microsoft Entra ID in Python.

Requirements

• Install azure-identity package from pypi.org.

  python -m pip install azure-identity

• Install azure-messaging-webpubsubservice package from pypi.org.

  python -m pip install azure-messaging-webpubsubservice

Sample codes

1. Create a TokenCredential with Azure Identity SDK.

   from azure.identity import DefaultAzureCredential
   
   credential = DefaultAzureCredential()

   credential can be any class that inherits from TokenCredential class.

   • EnvironmentCredential
   • ClientSecretCredential
   • ClientCertificateCredential
   • ManagedIdentityCredential
   • VisualStudioCredential
   • VisualStudioCodeCredential
   • AzureCliCredential

2. Then create a client with endpoint, hub, and credential.

   from azure.identity import DefaultAzureCredential
   
   credential = DefaultAzureCredential()
   
   client = WebPubSubServiceClient(hub="<hub>", endpoint="<endpoint>", credential=credential)
