Provide OData Services of Unbounce Data from a WCF Application



In this article, we will demonstrate the process of generating an OData feed for Unbounce data by developing a WCF Service Application.

The CData ADO.NET Provider for Unbounce enables you to rapidly develop service-oriented applications using the Windows Communication Foundation (WCF) framework, providing Unbounce data data to OData consumers. This article guides you through creating an entity data model for connectivity and a WCF Data Service to expose OData services. You can then consume the feed with various OData clients, such as Power Pivot or applications using the CData ADO.NET Provider for OData.

Create the OData Service

Follow the steps below to create a WCF service application that will provide connectivity to Unbounce data via OData.

  1. Open Visual Studio and create a new project. Select the WCF Service Application template.
  2. Delete the autogenerated IService.cs and Service1.svc.
  3. Install Entity Framework 6:

    Use the Package Manager Console in Visual Studio to install the latest version of Entity Framework. Run the following command to download and install Entity Framework automatically: Install-Package EntityFramework

  4. Register the Entity Framework provider:
    1. Add the following provider entry in the "providers" section of your App.config or Web.config file. This section should already exist if the Entity Framework installation was successful. <configuration> ... <entityFramework> <providers> ... <provider invariantName="System.Data.CData.API" type="System.Data.CData.API.APIProviderServices, System.Data.CData.API.Entities.EF6" /> </providers> </entityFramework> </configuration>
    2. Add a reference to System.Data.CData.API.Entities.dll, located in lib/4.0 in the installation directory.
    3. Build the project to complete the setup for using EF6.
  5. Click Project -> Add New Item -> ADO.NET Entity Data Model.
  6. In the Entity Data Model wizard that is displayed, select the 'EF Designer from Database' option.
  7. In the resulting Choose Your Connection dialog, click New Connection.
  8. In the Connection properties dialog, select the CData Unbounce Data Source and enter the necessary credentials.

    A typical connection string is below:

    Profile=C:\profiles\Unbounce.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;InitiateOAuth=GETANDREFRESH

    Start by setting the Profile connection property to the location of the Unbounce Profile on disk (e.g. C:\profiles\Unbounce.apip). Next, set the ProfileSettings connection property to the connection string for Unbounce (see below).

    Unbounce API Profile Settings

    Unbounce uses OAuth to authenticate to your data.

    In order to authenticate to Unbounce, you will first need to register an OAuth application. To do so, go to https://developer.unbounce.com/getting_started/ and complete the Register OAuth Application form.

    After setting the following connection properties, you are ready to connect:

    • AuthScheme: Set this to OAuth.
    • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
    • OAuthClientId: Set this to the Client Id that is specified in your app settings.
    • OAuthClientSecret: Set this to Client Secret that is specified in your app settings.
    • CallbackURL: Set this to the Redirect URI you specified in your app settings.

  9. Select Unbounce tables and views that you want OData clients to access.
  10. Click Project -> Add New Item -> WCF Data Service.
  11. Specify the data source class and configure access to the new WCF Data Service. In the example below, the Access Rule for the entities is set to All. This means that any user will be able to read and modify data.

    using System; using System.Collections.Generic; using System.Data.Services; using System.Data.Services.Common; using System.Linq; using System.ServiceModel.Web; using System.Web; namespace APIService{ public class APIDataService : DataService<APIEntities> { public static void InitializeService(DataServiceConfiguration config) { config.SetEntitySetAccessRule("*", EntitySetRights.All); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V3; } } }
  12. Run the project. Applications that support OData can now access the Salesforce data and reflect any changes. You can access the feed in your browser. The feed will resemble the following:

Consume the OData Service from Power Pivot

You can now use the service from any OData client; for example, Excel Power Pivot.

  1. Open Excel and click on the Power Pivot Window button.
  2. A new pop-up will appear. Select the option From Data Feeds.
  3. In the resulting Table Import Wizard, enter the OData URL. For example, http://localhost:12449/APIDataService.svc/.
  4. After connecting to the OData service, click the Next button at the bottom of the window.
  5. A table listing of the available tables will appear in the next window of the wizard. Select which tables you want to import and click Finish.
  6. Click Close to import the data in Power Pivot.
