In this interview, Erik Wilde and Thilo Frotscher – two of the curators of the CPSA®-Advanced Level module API: Application Programming Interfaces – explain why APIs are far more than technical interfaces. They discuss how APIs create business value, support digital transformation, and why successful API strategies require a combination of sound design, security, governance, and lifecycle management.
The conversation also explores how APIs are evolving in the age of AI. Erik and Thilo share insights into API governance at scale, the importance of Developer Experience (DX), and why emerging concepts such as Agent Experience (AX) are becoming increasingly relevant as AI agents interact with APIs. They also provide an overview of the topics covered in the CPSA®-Advanced Level module and explain who can benefit most from the training.
Key Takeaways
APIs are business assets, not just technical interfaces
Well-designed APIs create business value, enable innovation, and support digital transformation across organizations.
Business alignment is key to API success
Successful APIs reflect business capabilities and user needs rather than underlying technical implementations.
Governance matters at scale
Managing hundreds or thousands of APIs requires consistent standards, clear ownership, and effective governance practices.
AI is changing API design
As AI agents increasingly consume APIs, concepts such as Agent Experience (AX) become important alongside traditional Developer Experience (DX).
Successful APIs require more than technology
API design, security, lifecycle management, documentation, and collaboration all play a crucial role in building scalable and sustainable architectures.
This interview is a must-watch for software architects, developers, and technology leaders who want to design better APIs, govern them effectively at scale, and prepare their architectures for an increasingly AI-driven future.
