PowerShell Scripting to Replicate eBay Analytics Data to MySQL

The CData Cmdlets for eBay Analytics offer live access to eBay Analytics 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 Analytics and the CData Cmdlets for MySQL in PowerShell to replicate eBay Analytics data to a MySQL database.

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

You can authenticate to eBay Analytics only via the OAuth 2 authentication method. The eBay Analytics API requires an access token created with the authorization code grant flow to authorize the requests.

You can follow the guide in the Help documentation for a step by step guide on how to authenticate using the OAuth 2 protocol.

Collecting eBay Analytics Data

1. Install the module:

   Install-Module EbayAnalyticsCmdlets

2. Connect to eBay Analytics:

   $ebayanalytics = Connect-EbayAnalytics -OAuthClientId $OAuthClientId -OAuthClientSecret $OAuthClientSecret -RuName $RuName

3. Retrieve the data from a specific resource:

   $data = Select-EbayAnalytics -Connection $ebayanalytics -Table "TrafficReportByListing"

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

   $data = Invoke-EbayAnalytics -Connection $ebayanalytics -Query 'SELECT * FROM TrafficReportByListing WHERE ListingId = @ListingId' -Params @{'@ListingId'='201284405428'}

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 Analytics 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 Analytics 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 Analytics resource (TrafficReportByListing) and to exist in the database.

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

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

Notes

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

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

• If you wish to replicate the eBay Analytics 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-EbayAnalytics 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')}
