Dear Team
Can somebody help me with the Query String and the resource_path of this url
https://sandbox.api.visa.com/cybersource/v2/payments
i have been trying to post data to cyberspace Api
string QS = "apikey=" + ConfigurationManager.apiKey;
requestURL = "https://sandbox.api.visa.com/cybersource/v2/payments?" + QS
Here is what i want
string message = timestamp + resource_path + query_string + request_body
as per the above line of code
am able to get the timestamp (UTC) using this method
private static string getTimestamp()
{
long timeStamp = ((long)DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalMilliseconds) / 1000;
return timeStamp.ToString();
}
// what i use to generate the xpay token
private static string getXPayToken(string resourcePath, string queryString, string requestBody)
{
string timestamp = getTimestamp();
string sourceString = timestamp + resourcePath + queryString + requestBody;
string hash = getHash(sourceString);
string token = "xv2:" + timestamp + ":" + hash;
return token;
}
and here is the getHash method
private static string getHash(string data)
{
var hashString = new HMACSHA256(Encoding.ASCII.GetBytes(ConfigurationManager.sharedSecret));
var hashbytes = hashString.ComputeHash(Encoding.ASCII.GetBytes(data));
string digest = String.Empty;
foreach (byte b in hashbytes)
{
digest += b.ToString("x2");
}
return digest;
}
i still get UnAuthorised error code
Token validation failed
Thanks
