When design Goes wrong in APIs

8. Application Programming Interfaces (APIs)
are doors to information / functionality and
therefore enable digital strategies.

9. But even doors can be poorly designed…

10. 10
When does API design go wrong?
Design Build Package &
Deploy
Try
Design, build, package/deploy and
finally try happens in a sequential
way leading to feedback loops too
late in the cycle.
Waterfall’ish
API design1
Consequences:
 Long process
 APIs very difficult to change
 Compromise on design
Long Feedback-loop

11. Waterfall design or I’ll meet you half way?

Service design2
Developers design and build APIs
based on their backend systems
knowledge without feedback from
consumers (i.e. UI developers).
Consequences:
 APIs difficult to use, UI
developers try not to use them
 API endpoints don’t align to user
journeys

APIs are built on the fly throughout
the Sprints.
No design
because it’s agile3
Consequences:
 No API documentation
 Proliferation of APIs (hardly any
reuse)
 Dependent on individuals

Avoid rework: feedback early in the
cycle
By getting feedback very early in the
lifecycle, changes of rework late in the
cycle are slim. Saving time and cost.
1
Parallel development: Decouple App
dev from Service dev
By defining APIs with API Blueprints or
Swagger, app dev and service dev can
occur in parallel.
Agile: be ready for change
By continuously verifying service builds
against API definitions, non-compliant
updates can be detected quickly.

20. Why Oracle API Platform?
API
API-design ready with native
Apiary integration
Built from the ground-up to
satisfy modern API needs
First “native” hybrid API Platform.
Manage APIs anywhere (AWS, Azure,
OPC, on-prem)
Microservice ready. Lightweight,
easy to set-up and scale
Best licensing model based on
logical gateways –not CPUs

Stop the Slides –
Let’s Look at the real thing

27. The Lab – Your Mission …
Using APIary …
• Design an API that could be used to command a Drone
• Best API Blueprint provided – we’ll implement on top of a Drone SDK
• Make APIs accessible via API Platform
Then …
• Working on getting Oracle to invest in some programmable Drones, so next Meetup …
• Using Oracle cloud develop an App to use call the API & pilot the drones around a circuit
• Get too good and we’ll add API Policies to maker it trickier.
• Can you code like the Red Barron? Or land like Harrison Ford?
• We’ll be arranging a prize for the best API

28. Apiary & API Blueprint – Links to get
you started
Tips to get you going …
• https://Apiary.io
• API Blueprint Standard - https://apiblueprint.org/
• Tutorials –
• https://apiblueprint.org/documentation/tutorial.html
• https://apiblueprint.org/documentation/advanced-tutorial.html
• API Blueprint Spec – https://github.com/apiaryio/api-
blueprint/blob/master/API%20Blueprint%20Specification.md
Ask Luis, Angelo or Phil 
In terms of APIs needed – follow the guidance from Luis to design your APIs – think API First,
but to give you some ideas on the kinds of API that maybe needed..
