LINQ to UKG Pro HCM Data

This article illustrates using LINQ to access tables within the UKG Pro HCM via the CData ADO.NET Data Provider for UKG Pro HCM. 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 UKG Pro HCM Data Source".

4. Enter your data source connection information.

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

   UKGProHCM API Profile Settings

   UKG Pro HCM uses Basic authentication combined with a customer API key to authorize access to the API. To connect, you will need your UKG Pro HCM credentials and a customer API key issued by UKG.

   Set the following connection properties to authenticate:

   • AuthScheme: Set this to Basic.
   • User: Set this to your UKG Pro HCM username.
   • Password: Set this to your UKG Pro HCM password.
   • ProfileSettings: Set this to a semicolon-separated list containing:
     • Host: Your UKG Pro HCM tenant hostname (e.g., yourcompany.ultipro.com).
     • CustomerAPIKey: Your UKG customer API key. This is passed as the US-CUSTOMER-API-KEY request header on each API call.

   To obtain your customer API key, contact your UKG Pro HCM administrator or refer to the UKG Developer Portal at https://developer.ukg.com.

   Below is a typical connection string:

   Profile=C:\profiles\UKGProHCM.apip;AuthScheme=Basic;User=your_username;Password=your_password;ProfileSettings='Host=yourcompany.ultipro.com;CustomerAPIKey=your_customer_api_key';


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 userdetailsQuery = from userdetails in context.UserDetails
  select userdetails;

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

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