Build smarter productivity apps

Use the Microsoft Graph API to connect to the data that drives productivity – mail, calendar, contacts, documents, directory, devices, and more.

SEE EXAMPLES

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.

Build solutions that target enterprise users in Azure and Office 365, consumers on Office Online (Outlook.com and OneDrive.com), or both.
