7. Platform and Language Neutral
Internet-scale
Principles:
Our RESTful Approach
Platform and Language Neutral
Topology Neutral
Shared Architecture
Versioned
Optimized for cloud

8. Representational State Transfer (REST)
Architectural pattern that sees the internet as a collection of resources available at unique locations (URLs)
Resources are nouns/things
/platformservice/v1/applications/../communication is the URL of the Communication resource
Make HTTP requests to perform CRUD operations on resources
POST

9. REST – Navigating the Trusted App API
/platformservice
/application
/OnlineMeetings
/Communication
/startMessaging
/startAudioVideo
/joinOnlineMeeting
/AcceptAudioVideo
/AnonApplicationTokens
A response may contain links that can denote:
Resource – links between things
Capability – links that convey an action
Application should check for links in the response
Only make a request to the link if it is available
Don’t hardcode URLs in request
