i got an correct response in NAV 2016 with in bulit dll's like system.net.http and i con't find this dll in NAV 2009 R2 and my solution will not work this error message getting part because of dll so for that by R&D i found below link

    for usage with nav 2009 you need an older version of system.net.http. system.net.http is not part of .net framework, it's an additional library from nuget.

    for the older version of system.net.http, which is usable with .net framework 2.0/3.5, goto

    www.nuget.org/.../2.0.20710 and

    www.nuget.org/.../2.0.20710

    alternatively you could try to develope a code without using these nuget libraries.

    Hi Jonathan,

    i have used same HttpWebResponse when i get the response

    HttpWebResponse := HttpWebRequest.GetResponse;

    in the above statement i got an error "Remote server can be found (404) : Bad request" but this is not an exact error Email address not exist my error to get an exact error message i have used System.net.Http dll see below my code

    HttpContent := StringContent.StringContent(Json,SText.UTF8,'application/json');

    HttpClient := HttpClient.HttpClient;

    HttpClient.DefaultRequestHeaders.Authorization := HttpHeader.AuthenticationHeaderValue('Bearer','xg7s6d17jc70l6vebduhyxjugp4a78hk');

    HttpResponseMessage := HttpResponseMessage.HttpResponseMessage;

    IF MagentoConnectionP."HTTP Request Method" = 'POST' THEN

      HttpResponseMessage := HttpClient.PostAsync(MagentoRestAPIURL,HttpContent).Result;

    IF MagentoConnectionP."HTTP Request Method" = 'PUT' THEN

      HttpResponseMessage := HttpClient.PutAsync(MagentoRestAPIURL,HttpContent).Result;

    IF MagentoConnectionP."HTTP Request Method" = 'GET' THEN

      HttpResponseMessage := HttpClient.GetAsync(MagentoRestAPIURL).Result;

    HandleText := HttpResponseMessage.Content.ReadAsStringAsync().Result;

    ERROR(HandleText);

    see dll variables i used here

    Name DataType Subtype Length

    HttpResponseMessage DotNet System.Net.Http.HttpResponseMessage.'System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

    HttpClient DotNet System.Net.Http.HttpClient.'System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

    HttpContent DotNet System.Net.Http.HttpContent.'System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

    StringContent DotNet System.Net.Http.StringContent.'System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

    HttpHeader DotNet System.Net.Http.Headers.AuthenticationHeaderValue.'System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

    All the variables belongs to System.Net.Http dll but i con't find this dll in nav 2009 R2 is there any alternate solution for this.

    Thank You

    Ramesh

    Have you used postmaster google addon to check the response and request.

    May be your request is not correct.

    for usage with nav 2009 you need .net framework 2.0 (3.5). won't work with newer .net frameworks.

    System.Net.HttpWebResponse also exists in .net 2.0, assembly System.dll:

    'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Net.HttpWebResponse
