How to Get a Postman Bearer Token for Azure Resources

In this post, we will look at how to get a bearer token using Postman for connecting to Azure resources.

First, let’s open Postman and create a new collection, then a new Request:

Next, let’s create our request.

The URL we will hit is in the format https://login.microsoftonline.com/{tenantid}/oauth2/token. To find your Azure tenant id, go to https://portal.azure.com and search for Azure Active Directory:

Your tenant id is here:

Now add that to the Postman URL, so your request looks like this:

• https://admin.services.crm.dynamics.com/ (Flow Service)
• https://manage.office.com/ (Office 365 Management APIs)
• https://manage.office.com/ (Power BI Service)

Our request should now look like below. Click Send, and we see we get the Bearer token in the response:
