Connect to Perigon Data in CloverDX (formerly CloverETL)

The CData JDBC Driver for Perigon enables you to use the data transformation components in CloverDX (formerly CloverETL) to work with Perigon as sources. In this article, you will use the JDBC Driver for Perigon to set up a simple transfer into a flat file.

   Using API Key Authentication

   To use the Perigon API, you need to obtain an API key from your Perigon account. Navigate to the Perigon dashboard and generate an API key from your account settings.

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

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your Perigon API key.

   Example connection string:

   Profile=C:\profiles\Perigon.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key"
   

   Available Tables

   The Perigon profile provides access to the following tables:

   • Articles - News articles retrieved from the Perigon news intelligence API
   • Headlines - Story clusters grouping related headline articles
   • Sources - News sources tracked by the Perigon news intelligence API
   • Journalists - Journalist profiles tracked by the Perigon news intelligence API

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Perigon JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.api.jar
   

   Fill in the connection properties and copy the connection string to the clipboard.
