Restful Service Integration in AX 365

Introduction

This tip discusses how to consume external services inside AX 365. In this post, I am using channel advisor restful service to be consumed from Microsoft Dynamics 365. This will also help you know about calling GET, POST of restful service.

Background

I got a requirement of importing sales orders from channel advisor in AX , but after researching many websites, I haven't got a proper solution. I got everything in bits and pieces, so I thought of writing everything in one article.

Prerequisite

Create an account on "https://developer.channeladvisor.com/the-developer-console" for application key, secret key and refresh token.

Using the Code

1. Create a new Class Library project in Visual Studio, and name it CAIntegration as shown in the screenshot:

   

2. Create a Class Generateaccesscode.cs as shown below:
   C#

   public string GetAccessTokenByKey()
           {
               string content, accesstoken;
               //For getting access token by using refresh_token
               //var path = Path.GetTempPath();
               var bytes = Encoding.UTF8.GetBytes
                           ("[application id]:[secret key]"); // application id:secret key
               var base64 = Convert.ToBase64String(bytes);
               Console.WriteLine(base64);
               var client = new RestClient("https://api.channeladvisor.com/oauth2/token");
               var request = new RestRequest(Method.POST);
               request.AddParameter("Content-Type", 
                                    "application/x-www-form-urlencoded", ParameterType.HttpHeader);
               request.AddParameter("Cache-Control", "no-cache", ParameterType.HttpHeader);
               request.AddParameter("Authorization", "Basic " + base64, ParameterType.HttpHeader);
               request.AddParameter("application/x-www-form-urlencoded", 
               "grant_type=refresh_token&refresh_token=[RefreshToken]", ParameterType.RequestBody);
               IRestResponse response = client.Execute(request);
               content = response.Content;
               string json = content;
               XmlDocument doc = 
                   (XmlDocument)JsonConvert.DeserializeXmlNode(json, "Channeladvisor");
               XmlElement root = doc.DocumentElement;
               XmlNodeList nodes = root.SelectNodes("//Channeladvisor");
               accesstoken = "";
               foreach (XmlNode node in nodes)
               {
                   accesstoken = node["access_token"].InnerText;
                   //listBox1.Items.Add(node["game"].InnerText);
                   Console.WriteLine(node["access_token"].InnerText);
               }
               return accesstoken;
           }...

3. Create another class for getting sales order from channel advisor by passing access token above methods.
   C#

   public string GetAllOrders(string accesstoken)
           {
               string xml;
               // for orders
               var client = 
               new RestClient
                  ("https://api.channeladvisor.com/v1/orders?access_token=" + accesstoken);
               var request = new RestRequest(Method.GET);
   
               IRestResponse response = client.Execute(request);
               var content = response.Content;
   
               string json = content;
   
               XmlDocument doc = 
                   (XmlDocument)JsonConvert.DeserializeXmlNode(json, "Channeladvisor");
               xml = doc.InnerXml.ToString();
               return xml;           
           }
   ...

4. Deploy the class library.
5. Create a new Dynamics project in Visual Studio as shown in the screenshot.

   

6. Add CAIntegration.dll as a reference.
7. In the X++ class, you can use the external web services that were referenced in CAIntegration.dll.
   C#

   [FormControlEventHandler(formControlStr
   (wfsChannelAdvisor, FormButtonControl1), FormControlEventType::Clicked)]
   public static void FormButtonControl1_OnClicked(FormControl sender, FormControlEventArgs e)
   {
       Notes getOrdersXML;
       CAIntegration.GenerateAccessCode accessCode = new CAIntegration.GenerateAccessCode();
       String255 accessCode1 = accessCode.GetAccessTokenByKey();
       info(strFmt("Access code %1",accessCode1));
       CAIntegration.Orders orders = new CAIntegration.Orders();
       getOrdersXML = orders.GetAllOrders(accessCode1);
       info(strFmt("orderxml %1",getOrdersXML));
   } ...
