Rest API GET call JSON format using basic authentication in Dynamics 365 F&O / AX 7.0

In this post I'll be showing you how to send a GET call from dynamics 365 F&O system and the return format is in JSON.

Created a simple x++ job below. Please change according to your requirement.


class TestExternalCall_GET_JSON
{     
    /// <summary>
    /// Runs the class with the specified arguments.
    /// </summary>
    /// <param name = "_args">The specified arguments.</param>
    public static void main(Args _args)
    { 
     
        int                                                      find;
        str                                                      url,aosUri,activeDirectoryTenant;
        str                                                      activeDirectoryClientAppId;
        str                                                      activeDirectoryClientAppSecret;
        str                                                      postData,activeDirectoryResource;
        str                                                      aadClientAppSecret,oAuthHeader;
        str                                                      returnValue,jsonString,jsondszstr;
        System.Net.HttpWebRequest           request;
        System.Net.HttpWebResponse         response;
        System.Byte[]                                   byteArray;
        System.IO.Stream                             dataStream;
        System.IO.StreamReader                 streamRead;
        System.IO.StreamWriter                  streamWrite;
        System.Net.ServicePoint                  servicePoint;
        System.Net.ServicePointManager    servicePointmgr;
        System.Net.HttpVersion                   version;
        CLRObject                                        clrObj;
        Newtonsoft.Json.JsonReader            reader;
        System.Text.Encoding                      utf8;
        Counter                                             countCounter;
        Object                                               obj;
        Map                                                  data;
        System.Byte[]                   byteArraynew;

        System.Net.WebHeaderCollection headers = new System.Net.WebHeaderCollection();
     
        str  byteStr = strfmt('%1:%2', "USERNAME", "PASSWORD");
     
        new InteropPermission(InteropKind::ClrInterop).assert();

        headers = new System.Net.WebHeaderCollection();
     
        url = "Paste endpoint URL here";
     
        clrObj = System.Net.WebRequest::Create(url);
   
   
        request = clrObj;
        request.set_Method("GET");
        request.set_KeepAlive(true);
   
        request.set_ContentType("application/json");
        utf8    = System.Text.Encoding::get_UTF8();
        byteArraynew   = utf8.GetBytes(byteStr);
        byteStr     = System.Convert::ToBase64String(byteArraynew);

        headers.Add("Authorization", 'Basic ' + byteStr);
        request.set_Headers(headers);

        servicePoint = request.get_ServicePoint();

        System.Net.ServicePointManager::set_Expect100Continue(false);

        System.Net.ServicePointManager::set_SecurityProtocol(System.Net.SecurityProtocolType::Tls12);

   

        response = request.GetResponse();

   
        dataStream = response.GetResponseStream();


        streamRead = new System.IO.StreamReader(dataStream);

        jsonString = streamRead.ReadToEnd();

        info(strFmt("%1",jsonString));

        dataStream.Close();

        response.Close();
    }

}

In my next post I'll show you how to use OAUTH in GET call instead of normal authorization.

  3. When you use a genuine service, you will be able to provide instructions, share materials and choose the formatting style. outsourcing services

  4. Hi, did you ever create a blog on doing this but using Oauth at the authentication?
