15.  Single well-known resource
 Get (mostly) everything from a single endpoint
 Users, Groups, Mail, Calendars, Contacts
 Files, Tasks, People, Notes and more…
 Ease of development
 No more calling a different endpoint for each service
 No more obtaining separate tokens for different services
 Logical Navigation
 Platform flexibility

20.  Open standard for “authorization”
 not an “authentication” protocol
 Authorizes access to resources
 Uses token after third party authentication is done
 Provides secured delegated access on behalf of owner
 MS Graph API supports OAuth 2.0
 OpenID Connect
 works as identity layer - asserts identity
 How it works

22.  The Open Data Protocol
 “The best way to REST”
 Uses URL query string operators
 Simple, standard and readable expressions
 MS Graph API supports OData V4
22

23. 23

24.  https://graph.microsoft.com/{version}/{resource}?[query_param
eters]
 https://graph.microsoft.com = Microsoft Graph API endpoint
 Version = v1.0 or beta
 Resource = segment or path
 user, group, event, etc.
 Alias: me (logged in user), organization
 query_parameters (Optional) = $top, $count, etc.
24

25. $top – specific no. of items
$skip – skip items in result
$count – how many items
$select – specific property
$orderby – sort the result
$search – match a criteria
$expand – include child objects
25

26. Register the application
•MS App Registration Portal : https://apps.dev.microsoft.com
Register
Configure the project with ID & keyConfigure
Authenticate the user and get an access tokenAuthenticate
Call Microsoft Graph APICall
Show the result on UIShow
26

27.  New functionalities appear first in individual Office 365 REST
APIs
 Some functionality not yet available, some in preview
 Choosing your API endpoint
 Query parameter limitations
 $expand: only 1 level, no nextLink support
 $search: only available on some entities
 JSON batching
 Nested batching not allowed
 Delta query (change tracking)
 Not supported on data extensions
