Pipe eBay Data to CSV in PowerShell

The CData Cmdlets Module for eBay is a standard PowerShell module offering straightforward integration with eBay. Below, you will find examples of using our Ebay Cmdlets with native PowerShell cmdlets.

Creating a Connection to Your eBay Data

If you will be accessing your own account, you can generate an OAuthAccessToken from your developer account dashboard. You can also allow other users to securely access their own accounts.

Both of these methods require you to create an application key set to obtain values for the following connection properties: AppId, CertId, DevId, and SiteId.

The user consent flow additionally requires the RuName and CallbackURL.

See the "Getting Started" chapter in the help documentation for a guide to using OAuth.

$conn = Connect-Ebay  -AppId "$AppId" -CertId "$CertId" -DevId "$DevId" -SiteId "$SiteId" -RuName "$RuName" -CallbackURL "$CallbackURL"

Selecting Data

Follow the steps below to retrieve data from the ItemListing table and pipe the result into to a CSV file:

Select-Ebay -Connection $conn -Table ItemListing | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myItemListingData.csv -NoTypeInformation

You will notice that we piped the results from Select-Ebay into a Select-Object cmdlet and excluded some properties before piping them into an Export-Csv cmdlet. We do this because the CData Cmdlets append Connection, Table, and Columns information onto each "row" in the result set, and we do not necessarily want that information in our CSV file.

Deleting Data

The following line deletes any records that match the criteria:

Select-Ebay -Connection $conn -Table ItemListing -Where "ListingStatus = active" | Remove-Ebay

Inserting and Updating Data

The cmdlets make data transformation easy as well as data cleansing. The following example loads data from a CSV file into eBay, checking first whether a record already exists and needs to be updated instead of inserted.

Import-Csv -Path C:\MyItemListingUpdates.csv | %{
  $record = Select-Ebay -Connection $Ebay -Table ItemListing -Where ("Id = `'"+$_.Id+"`'")
  if($record){
    Update-Ebay -Connection $ebay -Table ItemListing -Columns ("Title","HitCount") -Values ($_.Title, $_.HitCount) -Where ("Id = `'"+$_.Id+"`'")
  }else{
    Add-Ebay -Connection $ebay -Table ItemListing -Columns ("Title","HitCount") -Values ($_.Title, $_.HitCount)
  }
}

As always, our goal is to simplify the way you connect to data. With cmdlets users can install a data module, set the connection properties, and start building. Download Cmdlets and start working with your data in PowerShell today!
