Customer is not updating through webservices using C#

[utpal_insync]

Hi All,

I am new to the PrestaShop development and I am developing an application using C# which will interact with the PrestaShop website through webservices. I have created the customer successfully but when I have tried to update the customer using the 'PUT' method it is giving the error

The remote server returned an error: (500) Internal Server Error

 

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(http://mysite.com/de...p/api/customers);

NetworkCredential nc = new NetworkCredential("8MMSYQ2VJIIJZKRLAVVRD50RHLP6TQSJ", "");

request.Credentials = nc;

request.Method = "PUT";

request.ContentType = "application/xml";

string str= " <customer>

<id>3</id>

<id_default_group xlink:href="http://templatebar.com/dev/prestashop/prestashop/api/languages/1">1</id_lang>

<newsletter_date_add>0000-00-00 00:00:00</newsletter_date_add>

</customer> ";

byte[] byteArray = Encoding.UTF8.GetBytes("xml=" +str);

request.ContentLength = byteArray.Length;

Stream dataStream = request.GetRequestStream();

dataStream.Write(byteArray, 0, byteArray.Length);

dataStream.Close();

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

if (request.HaveResponse)

{

 

using (Stream streamContenido = response.GetResponseStream())

{

MessageBox.Show(new StreamReader(streamContenido).ReadToEnd());

}

}

response.Close();

 

Please rectify if I have made any mistake.

Thanks and Regards
