You can't place an order with GET type request. You need a POST type request. You need to create a request to url with a spot Binance endpoint. Then put parameters you want there (symbol/volume/buy/sell/market/limit etc.). And then sign it with your Binance API key and secret using HMAC algorithm.
General info on sending requests to Binance can be found here:
https://binance-docs.github.io/apidocs/spot/en/#general-info
Info on placing spot orders is here:

Hello to all and thanks from now.
My code can send "Buy Market Orders" to Binace (SPOT) successfully, but only this. I'm trying to do the same for Sell, Limit, StopLimit, Getting Current account Info, etc. But I could not.
I need the URL structure for the mentioned other actions. Is there anyone can help me?

I'm also adding the whole code
