Digital working has moved from ‘nice to have’ to ‘business-critical’. However, as digital strategies mature, IT leaders are realising it’s important to look beyond the four walls of their own organisation to maximise their competitiveness.

It is impossible for a single organisation to have all of the best ideas, and this has led to the rise of what is known as the API economy. But what is an API?

API stands for Application Programming Interface, and can be thought of as a way for your technology to interact with everybody else’s. APIs are how companies embed Google Maps into their website, use Google or Facebook as a login portal and how mobile applications like Uber call back to the cloud. Simply put, they are a way to enable one program to communicate with another, without developers needing to know everything about how the other program works.

The ways in which IT professionals use APIs are extremely varied, and the market is going through a period of significant growth and change.

This report covers the following areas:

  • Interviews with IT leaders around how they are using APIs today.
  • The trends and challenges facing API use, including cybersecurity, regulation and the skills gap.
  • An analysis of the major vendors in the API management space: AWS, Apigee/Google, Microsoft, Mulesoft/Salesforce and more. The report covers their history, products and pricing, as well as – crucially – what sets them apart from each other.
