Update 2019-09-09: Add SharePoint REST API
What is a Tenant ID? When you subscribe to Microsoft 365, Microsoft provides you a full environment with several services (SharePoint, Teams, Azure Active Directory, etc.). In order to link all of these services between them and on your environment, they use a unique identifier which is your Tenant ID.
The Tenant ID is represented as GUID:
Generally, you do not need to know your Tenant ID but sometimes, essentially for the developers or when your company needs to deploy an app (ex: enable PowerBI Microsoft 365 Usage Analytics), you need to.
How to retrieve your Tenant ID? Here, some ways to find it!
Azure Active Directory
By default, all the users of your company have access to the Azure Portal.
Once you are connected to your https://portal.azure.com, click on
Azure Active Directory, then
Properties and this is the Directory ID
Microsoft 365 Admin Center
For the users accounts with at least the Reports reader role
Once you are connected to your https://admin.microsoft.com, expand
Reports from the left navigation and click on
Usage. At the bottom of the page, you should find the Microsoft 365 usage analytics with your Tenant ID.
SharePoint Admin Center (App permissions)
For SharePoint administrators only
Once you are connected to your SharePoint Admin Center (
https://yourdomain-admin.sharepoint.com), click on
Classic features from the left navigation, then click on
Open under Apps section and click on
App Permissions (last link).
On this page, you will see some Apps with a unique identifiers. Each identifier contains a claim with an ID followed by an at ("@") and your Tenant ID (ex: i:0i.t|ms.sp.ext|00000000-0000-0000-0000-000000000000@YOURTENANTID)
It is a little bit more complex to find the Tenant ID from a SharePoint site but you can do it too.
Open any modern SharePoint site (or classic) and open the Web Inspector / Web Developer Console
- On Windows, it is generally F12
- On MAC OS X, it is generally CMD + OPTION + i
Once opened, launch a search on "siteSubscriptionId"
- On Windows: CTRL + F
- On MAC OS X: CMD + F

Firstly, open your favorite web browser and go to any SharePoint site collection then, edit the URL like this:
