LINQ to Marketo Data

LINQ provides general-purpose query facilities in .NET Framework 3.0 and above and provides one easy way to programmatically access data through from CData ADO.NET Data Providers. This example uses LINQ to access information from the Marketo Data Provider.

This article demonstrates how to use LINQ to access Marketo tables through the CData ADO.NET Data Provider for Marketo. To do this you will LINQ to Entity Framework, which is used to generate the connection and can be used with any CData ADO.NET Data Providers to access data via 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 Marketo Data Source".
  4. Enter your data source connection information.

    Both the REST and SOAP APIs are supported and can be chosen by using the Schema property.

    For the REST API: The OAuthClientId, OAuthClientSecret, and RESTEndpoint properties, under the OAuth and REST Connection sections, must be set to valid Marketo user credentials.

    For the SOAP API: The UserId, EncryptionKey, and SOAPEndpoint properties, under the SOAP Connection section, must be set to valid Marketo user credentials.

    See the "Getting Started" chapter of the help documentation for a guide to obtaining these values.

    Below is a typical connection string:

    Schema=REST;RESTEndpoint=https://311-IFS-929.mktorest.com/rest;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting MarketoEntities 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 , update, delete, and insert commands. For example:

MarketoEntities context = new MarketoEntities(); var leadsQuery = from leads in context.Leads select leads; foreach (var result in leadsQuery) { Console.WriteLine("{0} {1} ", result.Id, result.Email); }

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