How to send authentication payload?

[paramsiddharth]

I am trying to use Postman to "connect" to a Socket.io server.

Using a regular client in NodeJS would look like this:

const io = io(url, {
    auth: {
        token: 123
    }
});

How to I pass this auth information while making a manual Socket connection? The documentations suggest that the new auth property is just query renamed, but I am unable to use query parameters in Postman to get it to work.

Yes, WebSocket requests in Postman are in beta. That could very much be the reason why I can't get it to work, but if any of you has tried this before and got it to work, please let me know. Thank you!

Hi! You must include the auth object in the CONNECT packet:

40{"token":"123"}

- 4 for Engine.IO "message" type
- 0 for Socket.IO "connect" type
- and then the JSON-encoded payload

Please note that Postman now has first-class support for Socket.IO: https://blog.postman.com/postman-now-supports-socket-io/

Thank you for your answer!

Have a look at the screenshot. Can you please guide me where I should put the auth object, the query parameters, the headers, or the payload, before clicking "Connect"?

Oh, I see, it seems the auth object is not supported yet. You can use the raw websocket then:

Hi
I don't know why Postman doesn't support this important feature. You can easily use the Firecamp Google extension instead.

Thank you for the answer!

@imanfattahi I am facing an issue on Firecamp while connecting to my local socket.io connection. Getting the following errors:

Tried passing both localhost and with the IP address in the URL.

Any suggestions on how to resolve it?
