TaxJar ADO.NET Provider

Rapidly create and deploy powerful .NET applications that integrate with TaxJar.

Are you looking for a quick and easy way to access TaxJar data from PowerShell? We show how to use the Cmdlets for TaxJar and the CData ADO.NET Provider for TaxJar to connect to TaxJar data and synchronize, automate, download, and more.

The CData Cmdlets for TaxJar are standard PowerShell cmdlets that make it easy to accomplish data cleansing, normalization, backup, and other integration tasks by enabling real-time and bidirectional access to TaxJar.

Cmdlets or ADO.NET?

The cmdlets are not only a PowerShell interface to the TaxJar API, but also an SQL interface; this tutorial shows how to use both to create, retrieve, update, and delete TaxJar data. We also show examples of the ADO.NET equivalent, which is possible with the CData ADO.NET Provider for TaxJar. To access TaxJar data from other .NET applications, like LINQPad, use the CData ADO.NET Provider for TaxJar.

After obtaining the needed connection properties, accessing TaxJar data in PowerShell consists of three basic steps.

To authenticate to the TaxJar API, you will need to first obtain the API Key from the TaxJar UI.

NOTE: the API is available only for Professional and Premium TaxJar plans.

If you already have a Professional or Premium plan you can find the API Key by logging in the TaxJar UI and navigating to Account -> TaxJar API. After obtaining the API Key, you can set it in the APIKey connection property.

Additional Notes

  • By default, the CData connector will retrieve data of the last 3 months in cases where the entity support date range filtering. You can set StartDate to specify the minimum creation date of the data retrieved.
  • If the API Key has been created for a sandbox API account please set UseSandbox to true, but not all endpoints will work as expected. For more information, refer to the TaxJar developer documentation.


  1. Install the module:

    Install-Module TaxJarCmdlets
  2. Connect:

    $taxjar = Connect-TaxJar -APIKey "$APIKey"
  3. Search for and retrieve data:

    $transactionid = "123" $orders = Select-TaxJar -Connection $taxjar -Table "Orders" -Where "TransactionID = `'$TransactionID`'" $orders

    You can also use the Invoke-TaxJar cmdlet to execute SQL commands:

    $orders = Invoke-TaxJar -Connection $taxjar -Query 'SELECT * FROM Orders WHERE TransactionID = @TransactionID' -Params @{'@TransactionID'='123'}


  1. Load the provider's assembly:

    [Reflection.Assembly]::LoadFile("C:\Program Files\CData\CData ADO.NET Provider for TaxJar\lib\System.Data.CData.TaxJar.dll")
  2. Connect to TaxJar:

    $conn= New-Object System.Data.CData.TaxJar.TaxJarConnection("APIKey=3bb04218ef8t80efdf1739abf7257144;") $conn.Open()
  3. Instantiate the TaxJarDataAdapter, execute an SQL query, and output the results:

    $sql="SELECT TransactionID, UserID from Orders" $da= New-Object System.Data.CData.TaxJar.TaxJarDataAdapter($sql, $conn) $dt= New-Object System.Data.DataTable $da.Fill($dt) $dt.Rows | foreach { Write-Host $_.transactionid $_.userid }

Update TaxJar Data


Update-TaxJar -Connection $TaxJar -Columns @('TransactionID','UserID') -Values @('MyTransactionID', 'MyUserID') -Table Orders -Id "MyId"


$cmd = New-Object System.Data.CData.TaxJar.TaxJarCommand("UPDATE Orders SET TransactionID='123' WHERE Id = @myId", $conn) $cmd.Parameters.Add(new System.Data.CData.TaxJar.TaxJarParameter("@myId","10456255-0015501366")) $cmd.ExecuteNonQuery()

Insert TaxJar Data


Add-TaxJar -Connection $TaxJar -Table Orders -Columns @("TransactionID", "UserID") -Values @("MyTransactionID", "MyUserID")


$cmd = New-Object System.Data.CData.TaxJar.TaxJarCommand("INSERT INTO Orders (TransactionID) VALUES (@myTransactionID)", $conn) $cmd.Parameters.Add(new System.Data.CData.TaxJar.TaxJarParameter("@myTransactionID","123")) $cmd.ExecuteNonQuery()

Delete TaxJar Data


Remove-TaxJar -Connection $TaxJar -Table "Orders" -Id "MyId"


$cmd = New-Object System.Data.CData.TaxJar.TaxJarCommand("DELETE FROM Orders WHERE Id=@myId", $conn) $cmd.Parameters.Add(new System.Data.CData.TaxJar.TaxJarParameter("@myId","001d000000YBRseAAH")) $cmd.ExecuteNonQuery()
