Call API using C#

[AnthonyV]

Hi,

 

How can i call the api webservice using c#? I cannot use uploadvalues or namevaluecollection because i'm using a silverlight application. This code and many others returns "result=error;message=Authentication Failed;"

 

WebClient wHMCSclient = new WebClient();
string data = "{ username, ****}, { password, **** }, { action, getinvoices }";
WHMCSclient.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
var data= WHMCSclient.UploadString("https://domain/includes/api.php",data);

Can someone please help me?

 

Thanks!

The above code was almost right.

Try this.

 

public static string GetWHMCSAPIResults(string anaction)

{

// Instantiate the WebClient object

WebClient WHMCSclient = new WebClient();

string username = "USERNAME";

string password = EncodeToMD5("PASSWD");

// Prepare a Name/Value collection to hold the post values

NameValueCollection form = new NameValueCollection();

form.Add("username", username);

form.Add("password", password); // the password will still need encoding is MD5 is a requirement

form.Add("action", anaction); // action performed by the API:Functions

form.Add("responsetype","xml");

 

// Post the data and read the response

Byte[] responseData = WHMCSclient.UploadValues("http://URL/includes/api.php", form);

 

// Decode and display the response.

//nsole.WriteLine("\nResponse received was \n{0}",

string result = System.Text.Encoding.ASCII.GetString(responseData);

 

if (result.Contains("result=error"))

{

result = null ;

}

 

return result;

 

}

 

 

 

public static string EncodeToMD5(string input)

{

// step 1, calculate MD5 hash from input

MD5 md5 = MD5.Create();

byte[] inputBytes = Encoding.ASCII.GetBytes(input);

byte[] hash = md5.ComputeHash(inputBytes);

 

// step 2, convert byte array to hex string

StringBuilder sb = new StringBuilder();

for (int i = 0; i < hash.Length; i++)

{

sb.Append(hash.ToString("X2"));

}

return sb.ToString();

}

Also make sure that the API user account has been setup, and that the IP addresses you are connecting to have been added to the setup.
