Today, we are excited to announce that Postman now supports WebSocket APIs. This key update to our API Platform is currently available in public beta with Postman v8.5 and above.

Support for the WebSocket protocol is one of the most popular feature requests we’ve received from the Postman community. The protocol enables continuous two-way communication between your browser and the web server, and for Postman, it has meant the advent of a whole new paradigm of asynchronous APIs.

In the latest version of Postman, you can now hit the “New” button in the left sidebar and open a WebSocket Request tab. In this tab, you can input your WebSocket API URL, establish a connection, then send and receive messages seamlessly. Take it for a spin and give us feedback in our WebSocket discussion forum.

From the very beginning, we noticed that the most arduous thing getting in the way of using WebSocket APIs is the very act of connecting to a WebSocket API server. To solve this problem, we leveraged what we do best—we used our knowledge of HTTP APIs and built a powerful interface that allows you to highly customize and debug the first connection (handshake) call that you make with the server. And, if you face issues connecting to your WebSocket API, Postman shows you detailed information of the handshake process.
