Create your custom web service and integrate with CRM 2011 Online

  • Artikel

I hope this article can help you understand when you need to create a middleware between CRM system and a Legacy system/or custom application.The below example talks about the “contact” entity where the web service accepts the “lastname” attribute of it and inserts the same into CRM system. The end result is the guid which is retrieved and confirms the successful execution of the operation.

Before we get started, here’s the list of requirements

  1. Microsoft Visual Studio 2010
  2. MS .NET Framework 4.0
  3. MS CRM SDK 2011

Walkthrough Steps: Web Service

  • Open Visual Studio 2010
  • Select your project, ASP.NET Empty Web Application
  • Select a suitable name of your project
  • On Successful Creation of Project
  • Go to Solution Explorer
  • Add New Item: Web Service

        
 

  • Provide a suitable name
  • Click on Add to create
  • You will see the C# content in “CustomWebService.asmx.cs”
  • Add reference to CRM Assemblies

     

  • Adding another .NET assemblies

 
      

  • Adding Live ID Code File available in CrmSdk (SDK\samplecode\cs\helpercode)
  • Declare the namespace

        

  • Write the code for CRM

/// <summary>
/// This function accepts the lastname and creates a contact with that in CRM
/// </summary>
/// <param name="lname"></param>
/// <returns></returns>
public string CreateContact(string lname)
{
     string message = string.Empty;
     try
     {
     OrganizationServiceProxy serviceProxy;
     ClientCredentials deviceCredentials = null;
     ClientCredentials clientCredentials = null;
     Guid contactId = Guid.Empty;
    
     //Organization URL
     Uri OrganizationUri = new Uri(String.Format("https://{0}.api.crm.dynamics.com/XRMServices/2011/Organization.svc","<<Organization>>"));
     //Discovery URL
     Uri HomeRealmUri = new Uri(String.Format("https://dev.{0}/XRMServices/2011/Discovery.svc", "crm.dynamics.com"));
     //Setting Client Credentials
     clientCredentials = this.GetCredentials("<<Live Id>>", "<<Live Password>>");
     //Get the Device Id and Password
     deviceCredentials = this.GetDeviceCredentials();
     //Using Organization Service Proxy to instantiate the CRM Web Service
     using (serviceProxy = new OrganizationServiceProxy(OrganizationUri, HomeRealmUri, clientCredentials, deviceCredentials))
     {
          // This statement is required to enable early-bound type support.
          serviceProxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());
          IOrganizationService service = (IOrganizationService)serviceProxy;
          //Define Entity Object
           Entity contact = new Entity("contact");
          //Specify the attributes
          contact.Attributes["lastname"] = lname;
          //Execute the service
          contactId = service.Create(contact);
          //Confirmation Message
           message = "Contact Created with LastName:- " + lname + " Guid is" + contactId.ToString();

      }
     }
     catch (Exception ex)
     {
           message = ex.Message;
     }
     //returns the message
     return message;
}

  • Write the other functions used in the code above

        protected virtual ClientCredentials GetCredentials(string username, string password)
        {
            ClientCredentials credentials = new ClientCredentials();
            credentials.UserName.UserName = username;
            credentials.UserName.Password = password;
            return credentials;
        }

        protected virtual ClientCredentials GetDeviceCredentials()
        {           
          return Microsoft.Crm.Services.Utility.DeviceIdManager.LoadOrRegisterDevice();
        }

    Hi Vidhu,You can use java-script or jQuery libraries to call a web service on a button click. There are various articles available online. Also using ASP.net Ajax controls you can achieve that. For this you need to script manager and reference the asmx service.

    I need to be able to call this web-service from inside the CRM 2011 online plugin. from what I understand, I cannot set service reference; I can either use basicHttp binding or call the webservice but there are some issues. could you be able to elaborate on what is the better approach?

    Hi Ray,You can still use this way of calling inside the plugin using Late binding. If you're looking for ways to add service reference, then this is what you can need to look at blogs.msdn.com/.../ssis-2008-integration-with-crm-2011-on-premise.aspx. This post is dealing with WCF way to connect CRM. Let me know if that helps!!

    Hi Apurv,I have so for worked on development for CRM 2011 on-premise version.CRM 2011 is new to me.In case of on-premise we have all infrastructure such as windows server 2008,IIS 7 where we can deploy our own custom wcf services,we can use windows task schedular for scheduling our batch jobs,we can write custom reports using SSRS or write some SSIS batches.What are our options in case of CRM 2011 online version where we have no access to actual server machines?Client prefers online version in case he does not want to maintain any hardware/infrastructure on premise.

    Hi,I have the same case as 'Ray'. I have a plugin in CRM online 2011 that connects to external webservice, this service operates as data access layer (DAL) so that all logic is implemented in the plugin and the plugin accesses the CRM (get, create, update, ...), through the service.The problem is: when the plugin makes the request to the CRM through the web service (for example to get data from CRM), the service takes long time more than 2 mins, and so the plugin throws the timeout exception.On the other hand, if I make the same request from console application the crm returns data in short time.Can anyone help me please??
