Setting Up Microsoft Entra ID OAuth App

​

Overview

This guide walks you through creating an OAuth application in Microsoft Entra ID for use with Airia. This enables secure integration with Microsoft 365 Tools including Outlook, Teams, OneDrive, SharePoint, and the Graph MCP Server.

​

Prerequisites

Before you begin, ensure you have:

• Azure admin access - You need permissions to register applications in Azure AD
• Active Azure/Microsoft 365 subscription - Your organization’s Azure tenant
• Airia callback URL - Available in the Airia platform OAuth configuration page

---

​

Step 1: Access the Azure Portal

1. Navigate to the Azure Portal
2. Sign in with your organizational account that has admin privileges
3. In the search bar at the top, type “Microsoft Entra ID” or “Azure Active Directory”
4. Select Microsoft Entra ID from the results

---

​

Step 2: Register a New Application

1. In the Microsoft Entra ID overview page, look for Manage in the left sidebar
2. Click on App registrations
3. Click the + New registration button at the top

---

​

Step 3: Configure Application Registration

Fill out the application registration form:

​

Basic Information

1. Name: Enter a descriptive name for your application
   • Example: Airia OAuth Integration or Airia - Microsoft Services
   • This name will be visible to users during the consent process
2. Supported account types: Choose based on your needs
   • Recommended: “Accounts in this organizational directory only (Single tenant)”
   • This is more secure and appropriate for most enterprise use cases
   Single Tenant vs. Multi-Tenant

   • Single tenant: Only users from your organization can authenticate (recommended)
   • Multi-tenant: Users from any Azure AD organization can authenticate

   For most BYO OAuth use cases, single tenant is the appropriate choice.
3. Redirect URI:
   • Select Web from the dropdown
   • Enter your Airia callback URL(s) as shown on the OAuth configuration page
4. Click Register to create the application

​

Step 4: Copy Your Application (Client) ID

1. In the left sidebar, click on Overview
2. You’ll see the Application (client) ID prominently displayed
3. Click the copy icon next to the Client ID to copy it
4. Save this ID - you’ll need it for Airia configuration

​

Step 6: Generate a Client Secret

1. In the left sidebar under Manage, click Certificates & secrets
2. Click on the Client secrets tab
3. Click + New client secret
4. In the dialog that appears:
   • Description: Enter a meaningful description (e.g., “Airia OAuth Integration”)
