APIs Powering the Future of Communications


APIs have a big job to do. They enable apps to speak to other apps. They also help people communicate better.

When you’re building an app, why roll your own if there’s an API for that? Check out Postman’s latest featured list: APIs Powering the Future of Communications. These APIs are empowering the exchange of information and news. Make them part of your developer toolkit, and try them out by forking their collections to your own workspace.

Let’s see who made the list.


Vonage is a flexible and scalable cloud communications platform for voice, messaging, video, and data. In this blog, they tell us how you can use Postman for easier API call sequencing and a faster “Time to First API Call.” Their expansive collection shows how to access your account, numbers, SMS, Voice, and more via APIs. Try it out in this Vonage public workspace.


Courier allows you to notify users on any channel with one API, whether you’re building notifications via email, text, push, or chat.
