Handling errors with signature HMAC Sha256 in Api Binance API using C#
As a developer, you have probably encountered problems when connected to Binance API using the RestSharp and HMAC Sha256 signature. In this article, we will review the error message that occurs when attempting to authenticate with the API and provide guidance to solve the problem.
Error Message
The error message you are encountering is likely to be caused by an invalid or missing time stamp value in your API request. Specifically, he sees that Binance does not accept the “Timestamp” parameter in the API signature.
Solution: Add parameter timestamp
You can add TIMSTAMP parameter to your API request using the following format:
`Bash
QueryString: Symbol = LTCBTC & SIDE = Buy & Type = Limit & Timeinforce = GTC and Timestamp = 1643723906
`
Please note that you should replace “1643723906a real time stamp value for your API request.
Example code
Here is an example of how to add the "Timestamp” parameter using restsharp and C#:
`csharp
Use of the system;
Use of restsharp;
Binanceapiauth's name space
{
Public class program
{
Static Void Main (String [] ARGS)
{
// Replace with your API credentials
String apikey = "your_api_KEY";
String APISECRET = "Your_api_secret";
// Replace the symbol values, side, type and timeinforce
String symbol = "LTCBTC";
String side = "buy";
String type = "Limit";
String timeinforce = "GTC";
// Create an API request
VAR REQUEST = New Restrequest (" new restbasconfig {apiiversetson = "v3"});
// Add the TIMestamp parameter
request.addqueryparameter ("symbol", symbol);
Request.addqueryparameter ("side", side);
Request.addqueryparameter ("type", type);
Request.addqueryParameter ("Timeinforce", Timeinforce);
Var Response = New Lastresspons ();
Response.Request = Request;
Var result = AWAIT RSTSHARPRESTCLIENT.DEFAULTINSTANCE.EXECUTYSYNC (Response);
Console.writine (result);
}
}
}
