Configure Rest API

Enabling REST API access will allow you to use multi-factor authentication as configured in your Microsoft 365 account. Once enabled, the user will be diverted to the Microsoft 365 login portal for authentication to use M365 Manager Plus. REST API is also essential to generate reports on your Microsoft 365 setup.

Steps to configure REST API

Automatic configuration

1. Login to M365 Manager Plus' admin portal.
2. Choose the Tenant Settings option found at the top right corner.
3. Select the Enable Now option found under the Rest API Access column, corresponding to the Microsoft 365 tenant for which REST API access must be enabled.
4. You will be diverted to the Microsoft 365 login portal. Enter the credentials of the global admin account you had configured in M365 Manager Plus.
5. Click Sign-in.
6. An application for M365 Manager Plus will be created automatically. And, you will now see a page that displays the list of permission that the application needs.
7. Go through the list and click Accept.
8. You will now be redirected to M365 Manager Plus console and REST API Access will be Enabled for the account you configured.
