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?
This question is related to
postman
hoppscotch
The answer is
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
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.
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.
You can use the tool APIC available here https://chrome.google.com/webstore/detail/apic-complete-api-solutio/ggnhohnkfcpcanfekomdkjffnfcjnjam. This tool allows you to test websocket which use either StompJS or native Websocket. More info here at www.apic.app
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
Postman doesn't support it, but WebSocket King does.
This is not possible as of May 2017, because Postman only works with HTTP methods such as POST, GET, PUT, DELETE.
P/S: There is a request for this if you want to upvote: github.com/postmanlabs/postman-app-support/issues/4009
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); });
Postman currently does not support that.
