How to get Azure Access Token using Postman

This is part 2 of the series “Create Azure Resource Manager Bot“.

An access token contains claims that you can use in Azure Active Directory B2C (Azure AD B2C) to identify the granted permissions to your APIs. When calling a resource server, an access token must be present in the HTTP request. An access token is denoted as access_token in the responses from Azure AD B2C.

For more information. Refer Microsoft Documentation.
