Hello Team,

I need 1 help.

I have a web api for updating records.

I am trying to update records, but I am getting error.

I am sharing my code -

public String LoadUpdateIDOFSerialNumber(string id)
{
string resulat = "";
string strUrl = "";
string postdata = "";
try
{
strUrl = http://10.10.10.10/rs/fortpolio/aid/12345;
strUrl = string.Format(strUrl);
if (strUrl != "")
{
HttpWebRequest requestobjPost = WebRequest.Create(strUrl) as HttpWebRequest;
requestobjPost.Method = "POST";
requestobjPost.ContentType = "application/xml";
requestobjPost.Credentials = new NetworkCredential("user", "user@123");
postdata = "1";
using (var streamWriter = new StreamWriter(requestobjPost.GetRequestStream()))
{
streamWriter.Write(postdata);
streamWriter.Flush();
}
var httpresponse = (HttpWebResponse)requestobjPost.GetResponse();
using (StreamReader reader = new StreamReader(httpresponse.GetResponseStream()))
{
resulat = reader.ReadToEnd();
}
}
else if (strUrl == "")
{
resulat = "Bad Request";
}
}
catch (Exception err) { err.Message.ToString(); }
return resulat;
}

Error - The remote server returned an error: (405) Method Not Allowed.

Please help in solving this issue.

he postman screen shot that you have attached , is actually not returning any data. Basically your API response is empty.

Below image shows line 1, 2, 3. API response should conatin a text like this.

Are you calling this api from same application or another one?

Can you share the sample?
You might need to enable CORS.
try adding this.
[EnableCors(origins: "*", headers: "*", methods: "*")]
