POST Data to External Html Form Data from Custom Action using HTTPWebRequest POST Not allowing

Posted on by Community Member Microsoft Employee

Hi All,

We need to Send Data from CRM  and to Perform Submit Button Automatically with this data on External Application.

I have tried the same request call from Console Application its working fine.

Am working on Dynamics365 - Onpermises.

But it's not working in either Custom Action or Plugin. It's Crashing at GetRequestStream() when we try to Debug.

facing Issue in Custom Action . Code used in Custom Action like Below..

HttpWebResponse httpWebResponse = null;

Stream requestStream = null;

Stream responseStream = null;              

var req = (HttpWebRequest)WebRequest.Create("http://xxxxx/form.do");

var postData = "agnCI=8";

   postData += "&agnFN=DOI-2-Save";

   postData += "&agnSUBSCRIBE=1";

var data = Encoding.ASCII.GetBytes(postData);

req.Method = "POST";

req.ContentType = "application/x-www-form-urlencoded";

req.ContentLength = data.Length;

requestStream = req.GetRequestStream();

requestStream.Write(data, 0, data.Length);

requestStream.Close();

httpWebResponse = (HttpWebResponse)req.GetResponse();

var responseString = new StreamReader(httpWebResponse.GetResponseStream()).ReadToEnd();

 Can anyone help on my request?

Thanks,

Shiva K

    Hi Shiva ,

    Could you please try rewrite your code  like below. I have tested ,this is working code from CRM . 

    And also try to make a log , or enable trace so that you can understand which line its failing.

                    var webrequest = (HttpWebRequest)System.Net.WebRequest.Create("http:\\testURL");
                using (var response = webrequest.GetResponse())
                using (var reader = new StreamReader(response.GetResponseStream()))
                {                   
                    var result = reader.ReadToEnd();                   
                    var serializer = new JavaScriptSerializer();
                    myClassdata pa = serializer.Deserialize<myClassdata>(result);
                   
                }

    Hope this helps.

    Thank you All... Traced the Error , Its because of Validations at External Site .. Where Email Address is Mandatory to submit the form.

    Plugin Profiler doesn't work fine with external calls. Try to use Tracing instead for troubleshooting.

    {  "@odata.context":"xxxx.com/.../v8.1$metadata#Microsoft.Dynamics.CRM.XRMEMMCustomActionResponse","JSONOutput":"Error - Step 2!"

    Hi David,

    Getting Response Back as Error 2! ... And Status Code is Success.

    But We debug the Code using Plugin Profiler.. it Crashing the debbuger at

    requestStream = req.GetRequestStream();

    1)Yes Plugin Deployed in the Sandbox.

    2)yes its external URL on a standard Http Port.

    What error do you get ?

    And a couple more questions:

    • Is the plugin deployed in the sandbox or not, and does it make a difference if you change this ?
    • Is the external url on a standard http port (80 or 443), or a different port

Under review
