Using the client ID and Client secret we can generate the Tenant ID from the postman tool – but that process is complicated, in this article In 4 steps access SharePoint online data using the postman tool has explained how we can generate Tenant ID using the postman tool.

Another easier way, we have explained how we can quickly get the Tenant ID from the Azure Portal and Azure PowerShell.

In this article, we will learn quicker than the previous two approaches, how we can get the Tenant ID from SharePoint Online page itself step by step, in order to configure the App Only Authentication, we must follow the below two steps:

Step 1: Register your app on the SharePoint site

Example:

 "https://globalsharepoint2020.sharepoint.com/sites/CustomSearchRND/_layouts/15/appregnew.aspx"

Click on the create button and Note down the above information:

Client Secret: 8T2E0dlaOZ4UuRH9bzKEvl8rB9YMQR7SmIIZhUAXDg0=

Here we can see the two pieces of information:

• App Display Name
• App Identifier

In-App, in the Identifier section, after the @ symbol, whatever we can see is, the Tenant ID, and before the @ symbol, is the client id.
