Build for Developers
Book about Application Developers as Customers in API Economy
What's included? Buy it now!

Themes covered

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 part.

APIs as products

In the part one you'll learn why APIs should be seen as products and what it means in practice. We will use existing great productised APIs as examples to avoid purely theoretical viewpoint.

Developer-first approach

In the second part we'll go through features and aspects on API development to focus on while keeping primary customer - application developer at the center. You will learn what kind of team you'll need to craft APIs your customers will love and why APIs mentioned in part I are successful.

Business to Developer marketing

In the third part we'll guide you towards successful Business to Developer marketing (B2D). You'll learn how to get started and things to avoid. Without proper marketing your efforts have been in vain and waste of time and resources.

All the topics discussed previously are wrapped up in separate concluding part about Developer portals.

Planned chapters are introduced below as well as schedule.
