Ethereum: VB.NET order binance keep getting error 400

I can help you troubleshoot the issue with getting an error code of 400 using the Binance API in VB.NET.

Error 400: Command Issue

The command issue error typically occurs when there’s a problem with the command or data sent to the API. Here are some potential causes and solutions:

• Invalid API Key: Make sure you’re using the correct API key. Double-check that the key is spelled correctly, and the API endpoint is correct (e.g.,

• Invalid Endpoint: Ensure that the API endpoint you're using is correct (e.g., and matches your desired action (e.g., selling an order, buying a market order, etc.).

• Invalid Parameters

  : Check that all parameters are included correctly. In this case, you’re using the orderType parameter with value sell. Make sure it’s set to sell instead of buy.

Here’s some sample code to get you started:

Imports BinanceAPI


Class OrderBinance VB.NET


    SubMain()

        Dim apiKey As String = "YOUR_API_KEY_HERE" ' replace with your API key

        Dim apiSecret As String = "YOUR_API_SECRET_HERE" ' replace with your API secret

        

        Dim binanceApi = New BinanceAPI(apiKey, apiSecret)

        

        ' Set the order type to sell (you can also set it to buy)

        Dim orderType As String = "sell"

        

        'Set the symbol and quantity

        Dim symbol As String = "ETHUSDT"

        Dim quantity As String = "0.1" ' 100 units

        

        'Create a new order

        Dim order As BinanceAPI.Order

        Try

            order = binanceApi.CreateOrder(orderType, symbol, quantity, "sell")

            

            If order.Success Then

                Console.WriteLine("Order created successfully!")

            Else

                Console.WriteLine("Error creating order: " & order.Error.Message)

            EndIf

        

        Catch ex As Exception

            Console.WriteLine(ex.Message)

        End Try

    End Sub

    

End Class
