Working with Paddle Data in LINQPad
The CData ADO.NET Provider for Paddle enables you to use standard ADO.NET interfaces like LINQ and the Entity Framework to work with Paddle data. This article will demonstrate the process of establishing a connection from LINQPad and executing LINQ queries.
Create the Data Model
After downloading and installing both the provider and LINQPad, create a new class library project within Visual Studio.
See the help documentation for a guide to setting up an EF 6 project to use the provider.
Right-click your project and click Add -> New Item -> ADO.NET Entity Data Model. In the resulting dialog, select Code First from database. Click New Connection and specify the connection string options in the resulting wizard.
Using API Key Authentication
Paddle uses API key authentication. To obtain an API key:
- Sign in to your Paddle account at https://vendors.paddle.com
- Navigate to Developer Tools > Authentication
- Click "Generate API Key"
- Assign the appropriate permissions for the data you wish to access
- Copy the generated key (sandbox keys begin with pdl_sdbx_apikey_; production keys begin with pdl_live_apikey_)
After obtaining your API key, set the following connection properties:
- AuthScheme: Set this to APIKey.
- APIKey: Set this to your Paddle API key.
Example Connection String
Profile=C:\profiles\Paddle.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";
Connecting to Paddle
Once the authentication is configured, you can connect to Paddle and query data from any of the available tables such as Products, Customers, Subscriptions, and Transactions.
Below is a typical connection string:
Profile=C:\profiles\Paddle.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";

Select the desired tables and views and click Finish to create the data model.

- Build the project. The generated files can be used to create the Paddle connection in LINQPad.
Connect to Paddle Data in LINQPad
After you have obtained the required connection properties and created the data model assembly, follow the steps below to start using the data model in LINQPad.
Open LINQPad and click Add Connection.
Select the "Use a typed data context from your own assembly" option.
Select Entity Framework DbContext.

Click Browse next to the Path to Custom Assembly box and browse to your project folder. Browse to the .dll or .exe under the bin folder.
- Select the name of the DbContext.
- If you saved your connection string in App.Config, specify the path to the App.config.
You can now query Paddle data through LINQPad. For examples of the supported LINQ queries, see the "LINQ and Entity Framework" chapter in the help documentation.
