Websocket Kline getting minute candlestick not monthly

I am sending a subscription to the websocket with the following adress:


The letter M is for monthly candles but i am getting the 1 minute timeframe, what i do wrong or is this never working?

The address is correct.

Could you please explain how you came to the conclusion that the result is returned in 1 minutes intervals instead of 1 month?

Providing a sample of a message received will help diagnose the issue further.

sorry, i have see that i was sending a wrong letter the api was working correctly
