An easy-to-use set of PowerShell Cmdlets offering real-time access to eBay data. The Cmdlets allow users to easily read, write, update, and delete live data - just like working with SQL server.

PowerShell Scripting to Replicate eBay Data to MySQL

Write a simple PowerShell script to replicate eBay data to a MySQL database.

The CData Cmdlets for eBay offer live access to eBay data from within PowerShell. Using PowerShell scripts, you can easily automate regular tasks like data replication. This article will walk through using the CData Cmdlets for eBay and the CData Cmdlets for MySQL in PowerShell to replicate eBay data to a MySQL database.

After obtaining the needed connection properties, accessing eBay data in PowerShell and preparing for replication consists of four basic steps.

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.

Collecting eBay Data

  1. Install the module:

    Install-Module EbayCmdlets
  2. Connect to eBay:

    $ebay = Connect-Ebay -AppId $AppId -CertId $CertId -DevId $DevId -SiteId $SiteId -RuName $RuName -CallbackURL $CallbackURL
  3. Retrieve the data from a specific resource:

    $data = Select-Ebay -Connection $ebay -Table "ItemListing"

    You can also use the Invoke-Ebay cmdlet to execute pure SQL-92 statements:

    $data = Invoke-Ebay -Connection $ebay -Query 'SELECT * FROM ItemListing WHERE ListingStatus = @ListingStatus' -Params @{'@ListingStatus'='active'}
  4. Save a list of the column names from the returned data.

    $columns = ($data | Get-Member -MemberType NoteProperty | Select-Object -Property Name).Name

Inserting eBay Data into the MySQL Database

With the data and column names collected, you are ready to replicate the data into a MySQL database.

  1. Install the module:

    Install-Module MySQLCmdlets
  2. Connect to MySQL, using the server address and port of the MySQL server, valid user credentials, and a specific database with the table in which the data will be replicated:

    $mysql = Connect-MySQL -User $User -Password $Password -Database $Database -Server $Server -Port $Port
  3. Loop through the eBay data, store the values, and use the Add-MySQL cmdlet to insert the data into the MySQL database, one row at a time. In this example, the table will need to have the same name as the eBay resource (ItemListing) and to exist in the database.

    $data | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "ItemListing" -Columns $columns -Values $values }

You have now replicated your eBay data to a MySQL database. This gives you freedom to work with eBay data in the same way that you work with other MySQL tables, whether that is performing analytics, building reports, or other business functions.


  • Once you have connected to eBay and MySQL in PowerShell, you can pipe command results to perform the replication in a single line:

    Select-Ebay -Connection $ebay -Table "ItemListing" | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "ItemListing" -Columns $columns -Values $values }
  • If you wish to replicate the eBay data to another database using another PowerShell module, you will want to exclude the Columns, Connection, and Table columns from the data returned by the Select-Ebay cmdlet since those columns are used to help pipe data from one CData cmdlet to another:

    $columns = ($data | Get-Member -MemberType NoteProperty | Select-Object -Property Name).Name | ? {$_ -NotIn @('Columns','Connection','Table')}
