9. 10 How do we ensure that the APIs we build are truly aligned with the business goals while keeping developer efficiency at the core?
10. API Value Proposition Canvas 11
11. What? 12
12. 13 APIs must solve business problems, enable new revenue streams, or support core operations. Developer Perspective Business Perspective APIs must be easy to understand, implement, and maintain while providing flexibility to adapt to different interaction patterns and technical requirements. API Value Proposition Canvas (AVPC) is a tool that helps mapping the needs of API consumers against the value an API provides. It ensures that every API delivers tangible business and user benefits while keeping the developer pain points in check.

22. 23 API development is more than just writing code or documenting endpoints. It's about solving real-world business problems through well-designed, scalable, and maintainable interfaces that create value.
23. 24 Traditionally, API Developer are people who write technical specifications and provide the glue between systems. The New Reality Key Concept 1: API Development as Problem Solver The Old View - Understanding the bigger picture. - Alignment of business goals - Beyond simply exposing data
24. 25 Create interfaces for systems without much input from other teams. The New Reality Key Concept 2: API Development’s Role Collaboration The Old View - Working closely with stakeholders - Understanding the needs of API consumers
25. 26 Handle the complexities of API documentation, versioning, and change management manually The New Reality Key Concept 3: Efficiency and The Right Tools The Old View - Focus on Efficiency - Automate repetitive tasks - Ensure consistency - Simplify version management
26. 27 Agenda The Shift Beyond OpenAPI The API Value Proposition Canvas Challenges of OpenAPI and the Need for Innovation Role of an API Developer TypeSpec
27. 28 We've all used OpenAPI, a reliable standard for API design. But as our needs evolve, so do our tools. Microsoft TypeSpec steps in—not to replace standards, but to extend and enhance them.
28. 29 Building on Standards’ Foundation Modular and Extensible API Design Developer-centri c Design Process Main Points
29. From AVPC to API Design with Typespec 30
30. 31 Define the core business objectives using the canvas. What value is the API supposed to deliver? Step 1 From Canvas to Design
31. 32 Define the core business objectives using the canvas. What value is the API supposed to deliver? Translate these insights into concrete API design elements. Focus on the aligning the API structure with business needs. Step 1 Step 2 From Canvas to Design
32. 33 Define the core business objectives using the canvas. What value is the API supposed to deliver? Translate these insights into concrete API design elements. Focus on the aligning the API structure with business needs. Use TypeSpec to generate the appropriate interaction patterns based on the design. Step 1 Step 2 Step 3 From Canvas to Design
33. 34 APIs designed using TypeSpec deliver measurable value - faster time to market, easier maintenance, and adaptability to future needs Developer Outcome Value for Both Sides Business Outcome Developers save time, reduce cognitive load, and focus on crafting APIs that solve business problems instead of managing technical debt or repetitive tasks.

35. 36 Efficiency Through Simplification Flexibility in API Interaction Patterns Sustainable Evolution and Collaboration 3 Key Principles
36. 37 Post-OpenAPI Era • Efficiency First • Business meets Development • Not every API needs to be REST "TypeSpec is the tool that brings developer efficiency and business value together."
