Features and Benefits of MailChimp Data Integration


MailChimp data integration via Layer2 Cloud Connector has the following features and benefits:


  • Connect and sync your MailChimp data with 100+ other data sources, e.g. native SharePoint lists in Office 365 or on-premises, keeping them always up-to-date.
  • High speed of implementation: No programming or tools required. Predefined sample connection templates included. Setup in a few minutes guided by wizards. Remote setup support (30 minutes are free).
  • Low risk in project: No installation or customizing for the SQL Server data sourceat the MailChimp or the data destination required. Just install the connector on a Windows computer in your network, in the cloud, or even your laptop.
  • Highest Security: Connection via secure web services (SSL). Disconnected systems: A connection is only required for data exchange – not for usage, e.g. MailChimp email sending. Users do not have direct access to external corporate data sources. You don't have to open your network for the Internet. The application runs where your data resides today - on a server or client inside your corporate network. No data is exposed to 3rd-parties or clouds.
  • Highest performance: Can manage very large data sets, also SharePoint lists and libraries. No 5,000 items limit. Can scale-out to multiple servers or to the Microsoft Azure Cloud, if required. No bulk-import, data changes are processed only.
  • Fully compatible with 3rd-party data providers: Data providers of the application vendors (e.g. Oracle, mySQL, IBM), 3rd-party data providers, or included Layer2 data providers can be used to access 100+ data sources.
  • Virtually any data sources supported: ODBC, OLEDB, OData, SOAP, Microsoft .NET based providers, Files (Excel, XML, CSV, Text), RSS / XML feeds, SQL databases like MS SQLSQL Azure, Oracle, MySQL, IBM DB2, IBM AS/400, IBM Informix; Notes, SharePoint, Office 365 (lists and libraries), local file systemcloud-based file storesExchangeActive DirectoryDynamics NAV/CRM, Navision, SAP, and many more. More complex data sources, REST-based web services, custom COM, or .NET objects can be connected using 3rd-party add-ons.

MailChimp Data Integration Specific Configuration Settings


​Let's take a sample MailChimp data set like ListMembers.





To connect to MailChimp data the data source or target entity must be configured as follows in the Layer2 Cloud Connector Connection Manager. No programming required, just a valid connection string and data query.


Example settings in the Layer2 Cloud Connector for MailChimp Integration



Please note the following specific settings.


  • To connect to MailChimp you have to select the MailChimp Data Provider.
  • You need to create or use existing API key in MailChimp (Account -> Extras -> API Keys)
  • You need to register your Layer2 Cloud Connector as "Registered App" in MailChimp (Account -> Extras -> Registered Apps).
  • You need to use AppId, ClientId and ClientSecret in the connection string.
  • You can use a connection string like this to connect:
    API Key=myApiKey;
    OAuth Client Id=myOAuthClientId;
    OAuth Client Secret=myOAuthClientSecret;
    Initiate OAuth=GETANDREFRESH;

  • The first time new credentials are used, your default browser will open a web page where you are asked to authorize access to your MailChimp account.
  • You can make use of all SQL queries. If you want to see all available tables and views, use this following selects:

    SELECT * FROM sys_tables
    SELECT * FROM sys_views
  • You can map your data fields to specific external fields in the Layer2 Cloud Connector. Please take care about data types (simple type conversions are supported).
  • Please enter an appropriate primary key (column(s) with unique values), depending on query (see data preview for this), for example for ListMembers "Id, ListId, UniqueEmailId"
  • Data synchronization can be started manually in the Connection Manager, per command line or scheduled in background by the Layer2 Cloud Connector Windows Service. Only data changes are processed (no delete / bulk import).
  • No programming required for setup a connection and sync. No need to open your local network for access from outside.


After successful connection you can map the data fields / columns as follows.





After first sync you fill find your MailChimp data connected, e.g. to Microsoft Office 365 or SharePoint as follows.



MailChimp Data Integration Known Issues and Workarounds


MailChimp Data integration via Layer2 Cloud Connector has the following known issues and workarounds:


  • In some configurations there are issues with creating new items in MailChimp (insert operations). Email addresses are read-only in some cases and used as a primary key, that cannot be changed in MailChimp.
  • No known issues with read, update, delete operations.
  • The first time new credentials are used, your default browser will open a web page where you are asked to authorize access to your MailChimp account. That's why the above will not work with other Layer2 Data Integration tools like the BDLC. But no problem with the Layer2 Cloud Connector.

MailChimp Data Integration Scenarios


Just some ideas for MailChimp data integration and synchronization:


  • Sync MailChimp data with Microsoft SharePoint or Office 365 for better collaboration (for example with customers or partners) or for intranet publishing. You can use contact lists, or custom lists, e.g. for reporting.
  • Sync with local SQL or SQL Azure for better reporting via SSRS.
  • Sync MailChimp contacts with Microsoft Exchange (on-premises or online) and Outlook for better mobile access and offline availability on any device.
  • Connect MailChimp with Microsoft Dynamics CRM/AX/NAV and others (like SAP) via Layer2 Odata Data Provider.
