Book about Application Developers as Customers in The API Economy

About the Book

Product and customer-centric approach with APIs will take you to success, but developer-centric will make you the industry leader


Dispite the fact that I love application developers, this book is written for business decision makers and marketing people in API Economy. After reading this you hopefully understand what your API consumers need and want to build best possible digital services. Successful APIs focus on primary customer and apply developer-first product strategy. You will learn what kind of team you'll need to craft APIs your customers will love. Book also provides guidance towards successful Business to Developer marketing (B2D). Without proper marketing your efforts have been in vain and waste of time and resources.

Three main topics

The book is built around three themes, each of which is one part of the book. The three themes are wrapped up in final Developer Portal focused concluding fourth part.
