Understanding asynchronous APIs

Click for: original source

If you’ve worked mostly with REST APIs, you might not be as familiar with asynchronous API protocols like WebSocket and gRPC. Asynchronous APIs allow you to stream data, send multiple requests at the same time, and manage communication intelligently between services, while synchronous APIs require you to make a new request every time you need data. By Melinda Gutermuth.

Let’s take a closer look at what makes asynchronous APIs different from synchronous APIs:

  • The difference between asynchronous and synchronous APIs
  • When to use an asynchronous API
  • Example asynchronous API use cases

In many cases, applications benefit from using a combination of synchronous and asynchronous APIs. While asynchronous APIs can offer perks like faster communication, quicker response times, and reliable scaling, there are advantages to synchronous APIs. Good read!
