What Are Asynchronous APIs?

As the use of APIs continues to grow, one particular style of APIs—those  that are asynchronous—is showing a noticeable increase. In this  incisive report, API design experts Mike Amundsen and Ronnie Mitra  describe the tools you need to successfully introduce the powerful  asynchronous API pattern into your organization.
Based on their field  experience, Amundsen and Mitra estimate that at least 60% of all API  developers will need to incorporate asynchronous interactions into their  APIs within the next five years. More applications today offer "instant  feedback," push notifications, and streaming data. The key component is  support for asynchronous APIs that push notifications and data directly  to the client as soon as it's available. This report will help you get  started on the basics.
