Register Your App: Go to the Azure Portal. Register a new application to obtain the client ID and secret. In the registered app configure the required permissions for Microsoft Graph API (such as Calendars.ReadWrite for calendar access). Install Necessary Packages: Code Sample- const express = require('express'); const axios = require('axios'); const msal = require('@azure/msal-node'); const app = express(); const config = { auth: { clientId: 'YOUR_CLIENT_ID' authority: 'https://login.microsoftonline.com/YOUR_TENANT_ID' clientSecret: 'YOUR_CLIENT_SECRET' } }; const cca = new msal.ConfidentialClientApplication(config); app.get('/login' (req res) => { const authCodeUrlParameters = { scopes: ['openid' 'profile' 'offline_access' 'Calendars.ReadWrite'] redirectUri: 'http://localhost:3000/redirect' }; const authUrl = cca.getAuthCodeUrl(authCodeUrlParameters); res.redirect(authUrl); }); app.get('/redirect' async (req res) => { const tokenRequest = { code: req.query.code scopes: ['openid' 'profile' 'offline_access' 'Calendars.ReadWrite'] redirectUri: 'http://localhost:3000/redirect' }; try { const response = await cca.acquireTokenByCode(tokenRequest); const accessToken = response.accessToken; // Use the accessToken to make requests to Microsoft Graph API const apiUrl = 'https://graph.microsoft.com/v1.0/me/calendar/events'; const headers = { Authorization: `Bearer ${accessToken}` }; const eventData = { // Your calendar event data here }; await axios.post(apiUrl eventData { headers }); res.send('Calendar event created successfully!'); } catch (error) { console.error(error); res.status(500).send('Error occurred during authentication.'); } }); const PORT = 3000; app.listen(PORT () => { console.log(`Server is running on port ${PORT}`); }); Replace 'YOUR_CLIENT_ID'  'YOUR_TENANT_ID'  and 'YOUR_CLIENT_SECRET' with your actual values. Note: Ensure that the redirect URI configured in your Azure app matches the URI specified in the code ( http://localhost:3000/redirect in this example).
