9. REST

10. Examples - Airline Reservation
LEVEL 0 POST - /api/get_people_details (ID in request body)
LEVEL 1 POST - /api/people/ (ID in request body)
LEVEL 2 GET - /api/people?id=12345
LEVEL 3 GET - /api/people?id=12345 with Hypermedia (HATEOAS)

11. HATEOAS
Hypertext As The Engine of Application state
is constraint by REST architecture style.
“A REST client needs no prior knowledge about how to interact with any particular
application or server beyond a generic understanding of hypermedia”

External Objects works similar to Custom objects.
● Tabs
● List View
● Detail Pages
● Chatter feeds
● Apex SObject Type
● API Access
● SOQL and SOSL queries
● Reports

17. Use Case

18. Apex Connector Framework
● Develop your own Custom Adapter in Apex using Apex Connector Framework.
● Apex manages the Metadata creation
● Provide your implementation for your data service
○ Sync
○ Query
○ Search

19. Considerations
➔ Do not support Salesforce Automations
➔ External object Metadata is external system driven
➔ Enable Separate Loading of Related Lists of External Objects
➔ Formula and Roll-up Summary fields not supported
➔ Field History tracking not supported
➔ Notes and Attachment not supported
➔ From Winter ’17 Report is supported with Data considerations
➔ 10,000 OData callouts per hour for Enterprise, Performance, and Unlimited Editions. Higher limits
are available on request
➔ 1,000 OData callouts per hour for Developer Edition
