Automate Perigon Integration Tasks from PowerShell

The CData API Driver for ADO.NET is a standard ADO.NET Provider that make it easy to accomplish data cleansing, normalization, backup, and other integration tasks by enabling real-time access to Perigon.

ADO.NET Provider

The ADO.NET Provider provides a SQL interface for Perigon; this tutorial shows how to use the Provider to retrieve Perigon data.

Once you have acquired the necessary connection properties, accessing Perigon data in PowerShell can be enabled in three steps.

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

1. Load the provider's assembly:

   [Reflection.Assembly]::LoadFile("C:\Program Files\CData\CData API Driver for ADO.NET\lib\System.Data.CData.API.dll")
    

2. Connect to Perigon:

    
   $conn= New-Object System.Data.CData.API.APIConnection("Profile=C:\profiles\Perigon.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key"")
   $conn.Open()
   

3. Instantiate the APIDataAdapter, execute an SQL query, and output the results:

   $sql="SELECT , from Articles"
   
   $da= New-Object System.Data.CData.API.APIDataAdapter($sql, $conn)
   $dt= New-Object System.Data.DataTable
   $da.Fill($dt)
   
   $dt.Rows | foreach {
   	Write-Host $_. $_.
   }
