Outlook REST APIs for Developing Against Outlook.com and Office 365

3-742

Session Objectives: • Why are the Office 365 REST APIs

Important?• Drill down into the API’s• Best practices• Compare with existing API’s like EWS• Sneak-peek into what is coming

Key Takeaways:• APIs that allows you to create end to end

Office 365 apps with targeted scopes

• Lightweight and quick to learn and develop

Agenda

Why Do These REST APIs Matter?

• 100’s of millions of Users Office 365 (now), Outlook.com (soon), hybrid and on-premises on our roadmap

• Engaged Users

• Powerful, intuitive way to access and manipulate Office 365 data

• Granular, tightly scoped permissions to access user data

• Based on open standards – OAuth 2.0, JSON, ODATA v4.0

Getting Started:Office 365 APIs starter Project – Visual Studio

• Provide instrumentation in your app• Add Header info like ‘user-agent’, ‘client-request-id’• Maintain a failure log for troubleshooting. • Include ‘client-request-id’ and all HTTP response headers from the

failed requests.

• Be mindful of requests that generate large responses

• Use $top, $select, $filter to narrow requests• App performance depends on it• Keep your app responsive by not getting throttled• Be conservative with refresh requests/frequent polling
