Vercel Connect now supports Microsoft

Vercel Connect now includes a managed connector for Microsoft, so your apps and agents can access all Microsoft products such as Teams, OneDrive and more.

As a Vercel Managed Connector, Vercel registers the Entra application and configures federated credentials for it, so you don't have to create an app registration or manage client secrets yourself. Authorize the app for your Microsoft tenant once, then attach the connector to the projects and environments it needs.

Create a connector from the dashboard or the Vercel CLI:

# Create a Microsoft connector
vc connect create microsoft --name acme-msft

# Attach it to a project
vc connect attach microsoft/acme-msft --project my-app --environment production

With the connector attached, your code requests a token only when it needs one. The @vercel/connect SDK authenticates with your deployment's OIDC identity and returns a short-lived token for the app itself, using the application permissions your admin granted:

1
import { getToken } from '@vercel/connect';
2

3
const token = await getToken('microsoft/acme-msft', {
4
  subject: { type: 'app' },
5
  scopes: ['https://graph.microsoft.com/.default'],
6
});
7

8
await fetch('https://graph.microsoft.com/v1.0/users/releases@acme.com/sendMail', {
9
  method: 'POST',
10
  headers: {
11
    Authorization: `Bearer ${token}`,
12
    'Content-Type': 'application/json',
13
  },
14
  body: JSON.stringify({
15
    message: {
16
      subject: 'Deploy finished',
17
      body: { contentType: 'Text', content: 'Production is live ✅' },
18
      toRecipients: [{ emailAddress: { address: 'eng@acme.com' } }],
19
    },
20
  }),
21
});

Each token is scoped to what you request and refreshed automatically, so there's nothing to leak or rotate. To act as a specific person instead, pass that user as the subject and the token carries their delegated permissions:

1
const token = await getToken('microsoft/acme-msft', {
2
  subject: { type: 'user', id: userId },
3
  scopes: ['User.Read'],
4
});
