Microsoft Azure Blob Retention Policy
Overview
To manage Azure Blob retention policies via WebAPI, you must obtain the following credentials:
Tenant ID
Client ID
Client Secret
Access Token
These values are required to authenticate and interact with Azure endpoints for retention policy operations.
What Is a Tenant and How to Get a Tenant ID in Azure?
A tenant represents your organization in Microsoft cloud services.
To get your Tenant ID:
Log in to the Azure portal.
Go to Entra ID > Properties.
Copy the value from the Directory ID field — this is your Tenant ID.
To create a new tenant:
Select Create a resource.
Search for and select Entra ID.
Provide a name for your new directory.
A Tenant ID will be auto-generated.
What Is a Client ID and How to Create It?
A Client ID (or Application ID) identifies your app to Azure AD.
To generate it:
Go to your Azure directory.
Click App registrations > New registration.
Select the Single-tenant option and click Register.
Go to Authentication, select app type as Web, and configure redirect URI.
The app will now show an Application ID — this is your Client ID.
Add a Client Secret
To create a Client Secret:
Open your app under App registrations.
Go to Certificates & secrets > New client secret.
Enter a description, select a duration, and click Add.
Copy the Client Secret ID and Value — they are shown only once.
Go to IAM settings and assign roles to your app via Add role assignment.
Generate Access Token
To generate an Access Token, follow these steps:
Step 1: Request Authorization Code
Send a GET request:
GET https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize?
client_id=YOUR_CLIENT_ID
