Interfaces

19. Platform
Interfaces
- Application Programming Interfaces -
APIs
- Aka REST APIs, HTTP APIs, JSON APIs, GraphQL
- Software Development Kits - SDKs
- Native “wrappers” or more experiential
- SDKs can have their own APIs

20. What are APIs
- Applications use APIs to interface with your application
- Humans use graphical user interfaces to interface with your application
- Or voice
- Or text
- Less adaptable
- APIs allows software to software operations on resources: Verb +
Noun
- Create
- Read
- Update
- Delete

21. Platform and API
Validation
- Cagan’s Four Big Risks
- Value risk
- Usability risk
- Write the docs first!

22. APIs
- Small building blocks
- Spend time designing, stress test your design
- Backwards compatible
- Don’t be afraid to version
- Do be afraid thoughtful of releasing new APIs, new fields, and
endpoints
- Lest you find yourself supporting it while doing The Big Rewrite™

23. Summary
- Platform: Shared data, experiences, value
- External, Internal, Hybrid
- Who is your customer - follow the money
- Even internal platforms have customers!
- Research the developer, and their
customer
- APIs
- Machines talking to machines
- Design, design, design
- Write the docs first
- Validate value, usability
