MailChimp Icon MailChimp ODBC Driver

The MailChimp ODBC Driver is a powerful tool that allows you to connect with live data from MailChimp, directly from any applications that support ODBC connectivity.

Access MailChimp data like you would a database - read, write, and update MailChimp Lists, Campaigns, Reports, etc. through a standard ODBC Driver interface.

Replicate MailChimp Data from PowerShell


Write a quick PowerShell script to query MailChimp data. Use connectivity to the live data to replicate MailChimp data to SQL Server.



The CData ODBC Driver for MailChimp enables out-of-the-box integration with Microsoft's built-in support for ODBC. The ODBC driver instantly integrates connectivity to the real MailChimp data with PowerShell.

You can use the .NET Framework Provider for ODBC built into PowerShell to quickly automate integration tasks like replicating MailChimp data to other databases. This article shows how to replicate MailChimp data to SQL Server in 5 lines of code.

You can also write PowerShell code to execute create, read, update, and delete (CRUD) operations. See the examples below.

Create an ODBC Data Source for MailChimp

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

You can set the APIKey to the key you generate in your account settings, or, instead of providing your APIKey, you can use the OAuth standard to authenticate the application. OAuth can be used to enable other users to access their own data. To authenticate using OAuth, you will need to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL by registering an app with MailChimp.

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

Connect to MailChimp

The code below shows how to use the DSN to initialize the connection to MailChimp data in PowerShell:

$conn = New-Object System.Data.Odbc.OdbcConnection $conn.ConnectionString = "DSN=CData MailChimp Source x64"

Back Up MailChimp Data to SQL Server

After you enable caching, you can use the code below to replicate data to SQL Server.

Set the following connection properties to configure the caching database:

  • CacheProvider: The name of the ADO.NET provider. This can be found in the Machine.config for your version of .NET. For example, to configure SQL Server, enter System.Data.SqlClient.

  • CacheConnection: The connection string of properties required to connect to the database. Below is an example for SQL Server:

    Server=localhost;Database=RSB;User Id=sqltest;Password=sqltest;

The SQL query in the example can be used to refresh the entire cached table, including its schema. Any already existing cache is deleted.

$conn.Open() # Create and execute the SQL Query $SQL = "CACHE DROP EXISTING SELECT * FROM " + $Lists $cmd = New-Object System.Data.Odbc.OdbcCommand($sql,$conn) $count = $cmd.ExecuteNonQuery() $conn.Close()

The driver gives you complete control over the caching functionality. See the help documentation for more caching commands and usage examples. See the help documentation for steps to replicate to other databases.

Other Operations

To retrieve MailChimp data in PowerShell, call the Fill method of the OdbcDataAdapter method. To execute data manipulation commands, initialize the OdbcCommand object and then call ExecuteNonQuery. Below are some more examples CRUD commands to MailChimp through the .NET Framework Provider for ODBC:

Retrieve MailChimp Data

$sql="SELECT Name, Stats_AvgSubRate from Lists" $da= New-Object System.Data.Odbc.OdbcDataAdapter($sql, $conn) $dt= New-Object System.Data.DataTable $da.Fill($dt) $dt.Rows | foreach { $dt.Columns | foreach ($col in dt{ Write-Host $1[$_] } }

Update MailChimp Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("UPDATE Lists SET Contact_Country='US' WHERE Id = @myId", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()

Insert MailChimp Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("INSERT INTO Lists SET Contact_Country='US' WHERE Id = @myId", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()

Delete MailChimp Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("DELETE FROM Lists WHERE Id = @myid", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()
