Ethereum: VB.NET order binance keep getting error 400

I can help you get error code 400 using Binance API in VB.NET.

Error 400: Problem with command

A „problem with command” error usually occurs when there is a problem with the command or the data sent to the API. Here are some possible causes and solutions:

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

• Invalid Endpoint: Make sure the API endpoint you are using is correct (e.g. and matches the desired action (e.g. sell order, buy market order, etc.).

• Invalid parameters

  : Make sure all parameters are included correctly. In this case, use the „orderType” parameter with the value „sell”. Make sure it is set to „sell” instead of „buy”.

Here is some sample code to get you started:

Import Binance API
VB.NET OrderBinance Class
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
Weak order As BinanceAPI.Order
Attempt
order = binanceApi.CreateOrder(orderType, symbol, quantity, "sale")
If row.Success Then
Console.WriteLine("The order was created successfully!")
More
Console.WriteLine("Error creating order: " & order.Error.Message)
End if
Catch exes as exceptions
Console.WriteLine(ex.Message)
End of attempt
End sat
End of lesson
