LINQ to Ontraport Data

This article illustrates using LINQ to access tables within the Ontraport via the CData ADO.NET Data Provider for Ontraport. To achieve this, we will use LINQ to Entity Framework, which facilitates the generation of connections and can be seamlessly employed with any CData ADO.NET Data Providers to access data through LINQ.

See the help documentation for a guide to setting up an EF 6 project to use the provider.

1. In a new project in Visual Studio, right-click on the project and choose to add a new item. Add an ADO.NET Entity Data Model.
2. Choose EF Designer from Database and click Next.
3. Add a new Data Connection, and change your data source type to "CData Ontraport Data Source".

4. Enter your data source connection information.

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

   Ontraport API Profile Settings

   In your Ontraport account, navigate to Administration > Integrations > ONTRAPORT API Instructions and Key Manager to obtain both your API Key and App ID.

   Below is a typical connection string:

   Profile=C:\profiles\Ontraport.apip;ProfileSettings='APIKey=your_api_key;AppId=your_app_id';


5. If saving your entity connection to App.Config, set an entity name. In this example we are setting APIEntities as our entity connection in App.Config.
6. Enter a model name and select any tables or views you would like to include in the model.

Using the entity you created, you can now perform select commands. For example:

APIEntities context = new APIEntities();

var campaignsQuery = from campaigns in context.Campaigns
  select campaigns;

foreach (var result in campaignsQuery) {
  Console.WriteLine("{0} {1} ", result.Id, result.Id);
}

See "LINQ and Entity Framework" chapter in the help documentation for example queries of the supported LINQ.
