1. @shepsheplu Battle-tested APIs: Tech and Business working together
3. @shepsheplu We are all working with - knowingly or not !
4. @shepsheplu But when we think about APIs this is always a technical point of view. • How is the API working ? • What technology do you use ? • Which cloud architecture ? ⚠ Never as a business opening solution.

8. @shepsheplu ?
9. @shepsheplu - Did you say API ? - Changing the world - but first the mindset - Bridge between Business / Engineering
10. @shepsheplu Vision of APIs
11. @shepsheplu Vision of APIs Today, both humans and machines are consuming data. Humans consume data through applications, often from many different devices • Smartphones • Laptops • Tablets • And desktops
12. @shepsheplu Vision of APIs But for companies APIs are mostly unknown to the majority of the people. An API is not a product it is only part of a more global - and most of the time - a visual product • We need an application to create a contract • We need to sign a pdf online • We want an internal social network
13. @shepsheplu Vision of APIs APIs is always hidden behind some complexity - yet this is the core of your system Remove the API part and everything collapse. • You can have an API without a frontend application • You can’t have a frontend application without APIs
14. @shepsheplu Vision of APIs APIs is always hidden behind some complexity - yet this is the core of your system Remove the API part and everything collapse. • You can have an API without a frontend application • You can’t have a frontend application without APIs
15. @shepsheplu Vision of APIs APIs is always hidden behind some complexity - yet this is the core of your system Remove the API part and everything collapse. • You can have an API without a frontend application • You can’t have a frontend application without APIs
16. @shepsheplu Vision of APIs APIs is always hidden behind some complexity - yet this is the core of your system Remove the API part and everything collapse. • You can have an API without a frontend application • You can’t have a frontend application without APIs
17. @shepsheplu So APIs are the core of your company, it IS the core product. Everything else is only a mean to display some items.
18. @shepsheplu Changing the world - but first the mindset
19. @shepsheplu Changing the world - but first the mindset What is API First ? • APIs are treated as “first-class citizens” • An API-first approach involves developing APIs that are consistent and reusable • Establish a contract for how the API is supposed to behave ◦ Involves spending more time thinking about the design of an API ◦ Involves additional planning and collaboration with the stakeholders
20. @shepsheplu Changing the world - but first the mindset APIs allow companies to break down capabilities into individual, autonomous services (aka microservices) An API-first strategy allows organizations to build APIs that serve all applications, and applications can be developed and maintained efficiently for all devices, platforms, and operating systems.
21. @shepsheplu Changing the world - but first the mindset Benefits of an API-First Approach • Parallel development • Cost reduction • Standardization • Speed to market • Better developer experience • Product oriented !
22. @shepsheplu Changing the world - but first the mindset We can define and design our API without writing code and so you can - and should - involve the business in the creation of the API • Using OpenAPI (v3.1 currently) standard ◦ Based on Swagger ◦ Example: https://editor.swagger.io/ • Writing Yaml or JSON
23. @shepsheplu Changing the world - but first the mindset We can define and design our API without writing code and so you can - and should - involve the business in the creation of the API • Using OpenAPI (v3.1 currently) standard ◦ Based on Swagger ◦ Example: https://editor.swagger.io/ • Writing Yaml or JSON
24. @shepsheplu Changing the world - but first the mindset With a governance group, you can then follow and standardize all the APIs in your ecosystem • Mixed group of people (Engineering & Business) • Guarantee compliance and use case • Validate new APIs • Monitor testing of APIs • Discover missing APIs
25. @shepsheplu Bridge between Business and Engineering
26. @shepsheplu Bridge between Business and Engineering With APIs now being a core product it is only normal that this should be known by the business - because it can bring value to the business • Opening APIs to new customers and markets • Having a monetization strategy (or not) • Get more data • Allow other business to rely on our APIs
27. @shepsheplu Bridge between Business and Engineering From the engineering side • Provide data to the business about the APIs • Be proactive about Analytics and Observability • Be a voice on all projects • Report success and failures • Do not hide complexity
28. @shepsheplu Bridge between Business and Engineering From the business side • Involve the engineering side for feedback earlier • Directly work with engineering to build feature • Be present for the testing phases • Ask feedback from engineering on a live project • Learn the basics about APIs
29. @shepsheplu Bridge between Business and Engineering On API directly, it can be a good idea to consider the API contract as the product • Build the openAPI spec with the business ◦ Better knowledge on the possibilities ◦ Good understanding of the use case ◦ Way to find new features that could be useful • Have the business involved in testing ◦ Final product is validated by the business ◦ Reuse tests done to have them setup in your pipelines ◦ Implement a “continuous business testing” policy
