401 Unauthorized

Hi, I have tried to login to websocket multiple times without success. Tried both live and demo endpoints, and it seems as soon as I open the connection, the server kicks me out This is the response I always get:

a[{"s":401,"i":1,"d":"\"Access is denied\""}]
Received closing frame Some(
    CloseFrame {
        code: Normal,
        reason: "Bye",

I know my auth token is good because I had a 200 http response when I got it. The websocket doesn’t even wait for me to send the auth message, it just immediately sends that after the initial “o”.
Here’s the url I used:
Any ideas on what I could be doing wrong?

Are you positive you aren’t sending anything at all? For example, are you sending malformed heartbeats? Meaning, anything other than []?

The server will still be expecting an authorize command and will reject something it interprets as a request.

In my experience, after some time (~20 seconds) it should drop your connection with “Bye” if you send no heartbeats at all.

@Juan_Marquez, make sure you send the auth message as a response to the ‘o’ open frame.

You can follow this guide.

make sure you send your response in this format:


Remember, the newlines are important.

Hope this helps!

@Alexander @Brady thank you guys still no success. I am not using the provided js library, I am writing my client in rust, which I have done for nearly all crypto exchanges that also use WebSockets and REST.
Here’s my app log to show you guys the messages I am sending and receiving.

Could this have something to do with 2FA? I received the unknown login email and went through the steps to authorize it, but it still didn’t work

Guys I got. My error was that I had only one \n before my token, and it needed two. :grinning:

@Alexander Hi Alex, can you point me to where I may find the tick stream data on the API?
Thank you

Hi @Juan_Marquez,

Probably your best bet for getting tick stream data is to use a Market Data WebSocket and make a request to getChart with the UnderlyingType set to 'Tick'.

You seem like you understand the basics of connecting a WebSocket, so you may want to look at the first and second parts of the Chart Data portion of the Tradovate WebSocket tutorials. Making a request to for a tick chart should fulfill your needs, but it’s a good idea to review both those sections for clarity’s sake.

Edit: Don’t forget to use the market data URL when hooking up the WebSocket - wss://md.tradovateapi.com/v1/websocket

Thank you @Alexander , yes so far working only with market data endpoint. Appreciate your help
