Microsoft Graph is the unified API for modern work

Use the data and intelligence in Microsoft 365 to build apps that interact with millions of users.

Rich context

Get rich context for your applications, such as who someone's manager is, whether they are out of office, or what documents they've been working on.

Deep insights

Access deep insights generated from usage patterns, such as trending documents, best team meeting times, or who people typically work with.

Real-time updates

Respond to changes in Microsoft Graph data in real time. Reschedule a meeting based on responses, notify others when a file is modified, or continue a process after it's been approved.
