Book Description

APIs are to today’s digital revolution what steam-powered engines were to the industrial revolution in the 18th Century. Valuable to consumers, organizations, developers and software vendors alike, APIs are often described as currency in a digital world. APIs are especially valuable to retailers and brands because they deliver the agility needed to quickly build customer experiences.

In this, his third O’Reilly book, author Kelly Goetsch, Chief Product Officer of commercetools, provides readers with both a high-level understanding of APIs, as well as how and why APIs are being used to re-invent commerce.

Read APIs for Modern Commerce to gain a solid understanding of:

  • What APIs are and why they are so valuable for digital commerce
  • How and why to model commerce APIs before the implementation
  • Building APIs using Microservices and how the two pair so well together
  • How to deploy commerce APIs
  • Consuming and extending APIs to achieve maximum flexibility and differentiation
