microsoft-graph-tools

This set of tools allows for interaction with the Microsoft Azure Graph API. The use case in which this tool was developed was to extract mail addresses from an Azure Active Directory.

Getting started

It is assumed you already have an Azure Portal account and active Azure Active Directory.

Dependencies

apt install curl jq

Getting credentials

Log into your Microsoft Azure Portal and open the Settings for your Azure Active Directory.
Open App Registrations and click New Application Registration
- Name it any way you like.
- The sign in URL needs to respond to your backend. You can change this later if you don't know the value yet. You can enter https://localhost as a placeholder.
- After creating the Application Registration, save the Application ID in the overview. This is your clientID.
- Open the Settings for your new application.
- Open Required Permissions
  - Click Add, select the Microsoft Graph API.
  - At least assign the following privileges (or all of them):
    - Application Permissions: Read all user mailbox settings (MailboxSettings.Read)
    - Application Permissions: Read all users' full profiles (User.Read.All)
  - Save the settings, then click 'Grant Permissions' in the list of applications. This is important.
- Open Keys and add a new password. Copy and keep the value - you won't be able to display it again. This password is your clientSecret.

Filling the config

Create a copy of the config.json template: cp config.json.tpl config.json
Open the copy in an editor of your choice and fill out the tenant, clientID and clientSecret field with the data you gathered in the previous step. The tenant is likely your mail domain (something.onmicrosoft.com or your own domain).

Getting your auth token

The Azure API works through a JWT-based authentication token. After filling out the config, the get-auth-token.sh script can generate a token for you. It will write it to the authtoken file and display the JSON payload contained within it.

Making requests

The REQ-endpoint.sh allows you to query arbitrary endpoints, e.g.:

$ ./REQ-endpoint.sh /users/xxxxxxxxxxxxxxxxxxxxx@yourdomain.onmicrosoft.com
