Steps to enable REST API access in O365 Manager Plus

Enabling REST API access in O365 Manager Plus will allow users to employ multi-factor authentication (MFA) as configured in their Office 365 account when they log in to O365 Manager Plus. Once enabled, users will be taken to the Office 365 login portal for MFA in order to use O365 Manager Plus.

Steps to configure REST API access

Automatic configuration

  1. Log in to the O365 Manager Plus admin portal.
  2. Select Tenant Settings in the top-right corner of the page.
  3. Select Enable Now under REST API Access for the Office 365 tenant of your choice.

    Automatic configuration

  4. You'll be taken to the Office 365 login portal. Enter the Office 365 password for the global admin account you are about to configure.
  5. Click Sign in.
  6. An application for O365 Manager Plus will be created automatically. You will now see a page that displays the list of permissions that the application needs.

    Note: If you'd like to modify the permissions required by the newly created O365 Manager Plus application, you'll need to manually configure REST API access.

If the automatic configuration failed because of permission issues, you'll need to configure REST API access manually. You'll need to fill in the appropriate values in the pop-up that appears when the automatic configuration fails. [Refer to the image below.]
