Websocket connections with Postman

I'm using Postman to test an existing REST API. This API calls async functions on the server which return a response over a websocket using StompJS.

Is it possible to connect to the websocket using Postman?

Its now possible in Postman.

In Postman, you can create a WebSocket request with a server, and use it to send and receive messages across the WebSocket connection.

Have not discovered that postman released web sockets function, but in any case i recently wrote my own simple very simple utility with pure js & html (no bootstrap, no npm, no heavy libs), maybe it would be useful for someone: https://github.com/Wissance/wstester

It's not possible in Postman yet; But there is a new alternative for Postman, named Postwoman. it's open source and supports realtime Websocket and SSE requests.

Update

It seems they have rebranded Postwoman to Hoppscotch and have improved the Websocket support.

Postman doesn't support websocket. Most of the extension and app I had ever seen were not working properly.

Solution which I found

Just login/ open your application in your browser, and open browser console. Then enter your socket event, and press enter.

socket.emit("event_name", {"id":"123"}, (res)=>{console.log(res); });

You can use Socket.io tester, this app lets you connect to a socket.io server and subscribe to a certain topic and/or lets you send socket messages to the server

I've run into this issue often enough that I finally created my own barebones GUI for testing websockets. It's called Socket Wrench, it supports

multiple concurrent connections to servers (with all responses and connections displayed in the same view),
comprehensive message history to enable easy re-use of messages, and
custom headers for the initial connection request.

It's available for Mac OS X, Windows and Linux and you can get it from here.

I ran into the exact same problem. Had to make a Web Socket call. I was able to accomplish this using Advanced Rest Client. I'm using ARC version : 12.1.3

As the previous comment mentioned you can't do this in Postman. however, I found this Chrome app in the web store. It is very simple, but it's working really well with my local web socket connections.
