hello comunity

Actually ,I try to call a web service using plugin on save event But I get this error

- The provided uri did not return any Service Endpoints!

Some action already tried (CRM 2015 on premises ) :

Restart async service
restart IIS
Recycle crmapppool

Result ==> The issue still occurs

Does any one face the same problem ?

Please let me know !!

Hi,

Please check trace log whether you are using correct endpoint url.

Are you able to call the web service endpoint using soap UI?

Hi

On top of what Goutam suggested/asked, couldyou share the bit of code that calls the web service

Is this external service or are you trying to call the CRM WCF service?

Hi,

The steps you have performed like reset iis, async service, crmapppool are relevant when you call CRM web services outside of CRM. You have mentioned you are calling web services from plugin so I will assume you are calling some external web service which means you need to ensure that that web service is accessible from your CRM box.

Also to rule out issue with plugin calling the web service, ensure that you are able to connect and get a response from that service using a console application from your local as well as from your crm box.

Hope this helps.

Hi- Did you try checking your web service outside Plugin, you can use utilities like postman (link below) to check your web services.

Thank you all for your responses.

The web service I used is deployed in the same server as CRM and respond well

here is the code I use

public int POST(string url, string jsonContent, string ApiKey)
{
int resp = 0;
int remainingTries = 3;
try
{
while (remainingTries > 0 && resp!=200)
{

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
request.Headers.Add("Authorization", "Basic " + ApiKey);
System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
Byte[] byteArray = encoding.GetBytes(jsonContent);
request.ContentLength = byteArray.Length;
request.ContentType = @"application/json";

using (Stream dataStream = request.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{

Stream responseStream = response.GetResponseStream();
StreamReader myStreamReader = new StreamReader(responseStream);
var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
var jsonObject = serializer.DeserializeObject(myStreamReader.ReadToEnd());

resp = (int)response.StatusCode;
}

}
}

remainingTries--;
}
catch (WebException we)
{
HttpWebResponse response = (HttpWebResponse)we.Response;
CommonUtils.WriteToEventLog(1, this.ToString(), EventLogLevel.Info, we.ToString(),"echec ws authentication");
if (response != null) { resp = (int)response.StatusCode; } else { resp = 0; };
}
return resp;

}
