Step-by-step instructions

To get data from Mailchimp using Microsoft Fabric, we first need to create an ODBC data source. We will later read this data in Microsoft Fabric. Perform these steps:

1. Download and install ODBC PowerPack (if you haven't already).

2. Search for odbc and open the ODBC Data Sources (64-bit):

   

3. Create a User data source (User DSN) based on the ZappySys API Driver driver:

   ZappySys API Driver

   
   • Create and use a User DSN if the client application runs under a User Account. This is the ideal option at design time (e.g., when developing in Visual Studio). Use it for both types of applications (64-bit and 32-bit).
   • Create and use a System DSN if the client application runs under a System Account (e.g., as a Windows Service). This is usually the required option in a production environment. If your Windows Service is a 32-bit application, you must use the 32-bit ODBC Data Source Administrator to configure this

4. When the Configuration window appears give your data source a name if you haven't done that already, then select "Mailchimp" from the list of Popular Connectors. If "Mailchimp" is not present in the list, then click "Search Online" and download it. Then set the path to the location where you downloaded it. Finally, click Continue >> to proceed with configuring the DSN:

5. Select your authentication scenario below to expand connection configuration steps to:

   • Configure the authentication in Mailchimp.
   • Enter those details into the ZappySys API Driver data source configuration.

   OAuth

   Mailchimp authentication

   To get the credentials you need in order to set up your OAuth workflow, you'll first need to register your application with Mailchimp:

   1. Login into your Mailchimp account, click on your Profile Icon, and hit Account & billing:
   2. Navigate to the Registered Apps page in your Mailchimp account:
   3. Click Register An App button:
   4. Fill-in the Register An App form and click Create button:
      NOTE: For Redirect URI use Redirect URI (also called "Redirect URL" or "Callback URL") given by your IT administrator or just use https://zappysys.com/oauth, if you don't have one.
   5. After successfully registering your application, you'll see the Client ID and Client Secret, record these values and store them securely:
   6. Record your Mailchimp data center, since we will need it later. The data center is located in your browser's address bar URL. If the URL is https://us21.admin.mailchimp.com/account/api, then your data center is us21.
   7. Now go to SSIS package or ODBC data source OAuth authentication configuration.
   8. Proceed by entering the data center into the Data Center field that was recorded in the previous step.
   9. Then enter the Client ID value into the Client ID field that you recorded in the previous step.
   10. Enter the Client Secret value into the Client Secret field that was recorded in the previous step.
   11. Click Generate Token. If proper authentication occurs, you will see a confirmation notice. If you get an error, click Yes on the dialog box and then a large browser window will launch. Then log into your Mailchimp account and approve the use of the application.
   12. Finally, hit the Test Connection button at the bottom of the window to verify proper connectivity with your Mailchimp account.
   13. If the connection test succeeds, select OK.
   14. Done! Now you can use Mailchimp Connector!

   API Connection Manager configuration

   Just perform these simple steps to finish authentication configuration:

   1. Set Authentication Type to OAuth [OAuth]
   2. Optional step. Modify API Base URL if needed (in most cases default will work).
   3. Fill in all the required parameters and set optional parameters if needed.
   4. Press Generate Token button to generate the tokens.
   5. Finally, hit OK button:

   ApiKey Auth

   Mailchimp authentication

   The simplest way to authenticate a request to the Mailchimp Marketing API is by using an API key (If you require access to Mailchimp on behalf of other Mailchimp users, you'll want to set up OAuth authentication instead)::

   1. Login into your Mailchimp account, click on your Profile Icon, and hit Account & billing:
   2. Navigate to the API keys page in your Mailchimp account:
   3. In the Your API keys section of the page, click Create A Key button:
   4. Give your new key a descriptive name that will remind you which application it's used for:
   5. Copy the API key immediately and store it in a secure location (you won't be able to see or copy the key once you finish generating it):
   6. Record your Mailchimp data center, since we will need it later. The data center is located in your browser's address bar URL. If the URL is https://us21.admin.mailchimp.com/account/api, then your data center is us21.
   7. Now go to SSIS package or ODBC data source ApiKey Auth authentication configuration.
   8. Proceed by entering the data center into the Data Center field that was recorded in the previous step.
   9. Then enter the API key into the Api Key field that you copied earlier.
   10. Finally, click the Test Connection button at the bottom of the window to verify proper connectivity with your Mailchimp account.
   11. Done! Now you can use Mailchimp Connector!

   API Connection Manager configuration

   Just perform these simple steps to finish authentication configuration:

   1. Set Authentication Type to ApiKey Auth [Http]
   2. Optional step. Modify API Base URL if needed (in most cases default will work).
   3. Fill in all the required parameters and set optional parameters if needed.
   4. Finally, hit OK button:

6. Once the data source connection has been configured, it's time to configure the SQL query. Select the Preview tab and then click Query Builder button to configure the SQL query:

   

   ZappySys API Driver - Mailchimp

   Read and write Mailchimp data effortlessly. Integrate, manage, and automate campaigns, lists, members, and reports — almost no coding required.

   MailchimpDSN

   

7. Start by selecting the Table or Endpoint you are interested in and then configure the parameters. This will generate a query that we will use in Microsoft Fabric to retrieve data from Mailchimp. Hit OK button to use this query in the next step.

   SELECT * FROM Campaigns

   
   Some parameters configured in this window will be passed to the Mailchimp API, e.g. filtering parameters. It means that filtering will be done on the server side (instead of the client side), enabling you to get only the meaningful data much faster.

8. Now hit Preview Data button to preview the data using the generated SQL query. If you are satisfied with the result, use this query in Microsoft Fabric:

   

   ZappySys API Driver - Mailchimp

   Read and write Mailchimp data effortlessly. Integrate, manage, and automate campaigns, lists, members, and reports — almost no coding required.

   MailchimpDSN

   SELECT * FROM Campaigns

   
   You can also access data quickly from the tables dropdown by selecting <Select table>.
   A WHERE clause, LIMIT keyword will be performed on the client side, meaning that the whole result set will be retrieved from the Mailchimp API first, and only then the filtering will be applied to the data. If possible, it is recommended to use parameters in Query Builder to filter the data on the server side (in Mailchimp servers).

9. Click OK to finish creating the data source.

Install Microsoft On-premises data gateway (Standard mode)

To access and read Mailchimp data in Microsoft Fabric, you must download and install the Microsoft On-premises data gateway (Standard mode). It acts as a secure bridge between Microsoft Fabric cloud services and your local Mailchimp ODBC data source:

There are two types of On-premises data gateways:

You can download the On-premises data gateway directly from the Microsoft Fabric or Power BI portals:

Link ODBC data source via the gateway

Follow these steps to download, install, and configure the gateway in Standard mode:

1. Download On-premises data gateway (standard mode) and run the installer.

2. Once the configuration window opens, sign in:

   
   Sign in with the same email address you use for Microsoft Fabric.

3. Select Register a new gateway on this computer (or migrate an existing one):

   

4. Name your gateway, enter a Recovery key, and click the Configure button:

   
   Save your Recovery Key in a safe place (like a password manager). If you lose it, you cannot restore or migrate this gateway later.

5. Once Microsoft gateway is installed, check if it registered correctly:

   • Go back to Microsoft Fabric portal

   • Click Gear icon on top-right

   • And then hit Manage connections and gateways menu item

   

6. Continue by clicking the On-premises data gateway tab and selecting Standard mode gateways from the dropdown menu:

   

   If your gateway is not listed, the registration may have failed. To resolve this:

   • Wait a couple of minutes and refresh Microsoft Fabric portal page
   • Restart the machine where On-premises data gateway is installed
   • Check firewall settings

7. Success! The gateway is now Online and ready to handle requests.

8. Done!

You are now ready to load data into Microsoft Fabric.

Load Mailchimp data into Microsoft Fabric

Now that we have configured the ODBC data source and installed the On-premises data gateway, we can proceed with loading data. You can accomplish this in two ways:

• Copy job
  Best for simple, high-speed data copying without modification.
• Dataflow Gen2
  Best if you need to transform, clean, or reshape data before loading.

Let's dive into the steps for both methods.

Use Copy job for high-speed loading

1. Go to the Microsoft Fabric Portal.

2. Select an existing Workspace or create a new one by clicking New workspace (ensure you are in the Home section):

   

3. Inside your workspace, click the New item button in the toolbar to start creating your data pipeline:

   

4. In the item selection window, choose Copy job to open the data ingestion wizard:

   

5. In the Choose data source screen, search for odbc and select the Odbc source:

   

6. Then enter your ODBC connection string (DSN=MailchimpDSN) and select MyGateway from the Data gateway dropdown we configured in the previous step:

   DSN=MailchimpDSN

   DSN=MailchimpDSN

   

7. Select the table(s) and preview the data you wish to copy from Mailchimp. Once done, click Next:

   DSN=MailchimpDSN

   

8. Choose your Data Destination. You can create a New Fabric item (like a Lakehouse or Warehouse) or select an existing one:

   
   In this example, we will use a Lakehouse as the destination.

9. Choose Full copy to load all data, or Incremental copy to load only changed data in subsequent runs:

   

10. Review the Column and Table mappings section:

    

11. On the summary screen, review your settings. You can optionally enable Run on schedule. Click Save + Run to execute the job:

    DSN=MailchimpDSN

    DSN=MailchimpDSN

    

12. The job will enter the queue. Monitor the Status column to see the progress:

    DSN=MailchimpDSN

    

13. Wait for the status to change to Succeeded. Your Mailchimp data is now successfully integrated into Microsoft Fabric!

    

14. Let's go to our Lakehouse (MyLakehouse) and verify the data:

    

15. Success! The data has been loaded.

Use Dataflow for advanced transformation

Another way to load data is by creating a Dataflow Gen2. This approach allows you to perform complex data transformations (ETL) before loading the data into its destination.

Configure Dataflow activity

1. Go to the Microsoft Fabric Portal.

2. Inside your workspace, click New item and select Dataflow Gen2:

   

3. In the Power Query editor, click Get data from another source:

   

4. Search for ODBC in the search bar and select the ODBC connector:

   

5. Then in the next step follow these instructions:

   • Enter your ODBC connection string (e.g., DSN=MailchimpDSN)
   • Expand Advanced options
   • Enter your SQL statement
   • Select your On-premises data gateway
   • Finally, click Next:
   DSN=MailchimpDSN

   DSN=MailchimpDSN

   SELECT * FROM Campaigns

   

6. You will see a preview of your Mailchimp data. You can now transform the data if needed (filter rows, rename columns, change types, etc.):

   Odbc.Query("DSN=MailchimpDSN", "SELECT * FROM Campaigns")

   

7. Now, let's send this data to the Lakehouse. Click the + button (Add data destination) at the bottom right and select Lakehouse:

   Odbc.Query("DSN=MailchimpDSN", "SELECT * FROM Campaigns")

   

8. Configure the destination connection settings and click Next:

   

9. Select your specific Lakehouse, enter the Table name you want to create, and click Next:

   

10. Uncheck Use automatic settings to set data update or schema options manually. Map the columns with proper data types and click Save settings when done:

    

11. The destination is now set. Click the Publish button to save the Dataflow:

    Odbc.Query("DSN=MailchimpDSN", "SELECT * FROM Campaigns")

    

12. Done! You can now start building reports using your new semantic model.

Configure and run Pipeline

Once you have created and published your Dataflow, you can use a Pipeline to orchestrate and run it.

1. Go to the Microsoft Fabric Portal.

2. Inside your workspace, click New item and select Data Pipeline to create a new pipeline.

   

3. In the pipeline editor, select the Dataflow activity from the toolbar to add it to your canvas:

   

4. Select the Dataflow activity on the canvas and click the Settings tab. Choose your Workspace and the Dataflow you created in the previous steps:

   

5. You are now ready to link the Dataflow with other Pipeline activities.

6. Once the Pipeline flow is configured, click the Run button at the top, then click Save and run to execute the pipeline:

   

7. Monitor the Output tab below. The Pipeline status will initially show as In progress:

   

8. Wait for the process to complete. The status will update to Succeeded, indicating your data has been successfully loaded via the Dataflow:

   

9. Done! You can now start building reports on your new semantic model.

Optional: Centralized data access via ZappySys Data Gateway

In some situations, you may need to provide Mailchimp data access to multiple users or services. Configuring the data source on a Data Gateway creates a single, centralized connection point for this purpose.

This configuration provides two primary advantages:

• Centralized data access
  The data source is configured once on the gateway, eliminating the need to set it up individually on each user's machine or application. This significantly simplifies the management process.
• Centralized access control
  Since all connections route through the gateway, access can be governed or revoked from a single location for all users.

To achieve this, you must first create a data source in the Data Gateway (server-side) and then create an ODBC data source in Microsoft Fabric (client-side) to connect to it.

Let's not wait and get going!

Create Mailchimp data source in the gateway

In this section we will create a data source for Mailchimp in the Data Gateway. Let's follow these steps to accomplish that:

1. Search for gateway in the Windows Start Menu and open ZappySys Data Gateway Configuration:

   

2. Go to the Users tab and follow these steps to add a Data Gateway user:

   • Click the Add button
   • In the Login field enter a username, e.g., john
   • Then enter a Password
   • Check the Is Administrator checkbox
   • Click OK to save
   

3. Now we are ready to add a data source:

   • Click the Add button
   • Give the Data source a name (have it handy for later)
   • Then select Native - ZappySys API Driver
   • Finally, click OK
   MailchimpDSN

   ZappySys API Driver

   

4. When the ZappySys API Driver configuration window opens, go back to ODBC Data Source Administrator where you already have the Mailchimp ODBC data source created and configured, and follow these steps on how to Import data source configuration into the Gateway:

   • Open ODBC data source configuration and click Copy settings:

     MailchimpDSN

     
   • Once a window opens, just paste the settings by pressing CTRL+V or by clicking right mouse button and then Paste option.

5. Once done, go to the Network Settings tab and Add a firewall rule for inbound traffic:

   
   • This will initially allow all inbound traffic.
   • Click Edit IP filters to restrict access to specific IP addresses or ranges.

6. Crucial Step: After creating or modifying the data source, you must:

   • Click the Save button to persist your changes.
   • Hit Yes when prompted to restart the Data Gateway service.

   This ensures all changes are properly applied:

   
   Skipping this step may cause the new settings to fail, preventing you from connecting to the data source.

Create ODBC data source to connect to the gateway

In this part we will create an ODBC data source to connect to the ZappySys Data Gateway from Microsoft Fabric. To achieve that, let's perform these steps:

1. Search for odbc and open the ODBC Data Sources (64-bit):

   

2. Create a User data source (User DSN) based on the ODBC Driver 17 for SQL Server driver:

   ODBC Driver 17 for SQL Server

   
   If you don't see the ODBC Driver 17 for SQL Server driver in the list, choose a similar version.

3. Then set a Name for the data source (e.g. Gateway) and the address of the Data Gateway:

   ZappySysGatewayDSN

   localhost,5000

   
   Make sure you separate the hostname and port with a comma, e.g. localhost,5000.

4. Proceed with the authentication part:

   • Select SQL Server authentication
   • In the Login ID field enter the user name you created in the Data Gateway, e.g., john
   • Set Password to the one you configured in the Data Gateway
   

5. Then set the default database property to MailchimpDSN (the one we used in the Data Gateway):

   MailchimpDSN

   MailchimpDSN

   
   Make sure to type the data source name manually or copy/paste it directly into the field. Using the dropdown might fail because the Trust server certificate option is not enabled yet (next step).

6. Continue by checking the Trust server certificate option:

   

7. Once you do that, test the connection:

   

8. If the connection is successful, everything is good:

   

9. Done!

We are ready to move to the final step. Let's do it!

Access data in Microsoft Fabric via the gateway

Finally, we are ready to read data from Mailchimp in Microsoft Fabric via the Data Gateway. Follow these final steps:

1. Go back to Microsoft Fabric.

2. Then, go to your Copy job or Dataflow and start configuring your ODBC data source (like you did in the previous step).

3. In the ODBC configuration window, configure these fields:

   • Enter your ODBC connection string (DSN format), for example: DSN=ZappySysGatewayDSN
   • Expand Advanced options and set the SQL statement
   • Select MyGateway from the Data gateway dropdown that you configured in the previous step
   • Select Basic from the Authentication kind dropdown
   • Enter the Username (e.g., john) and Password that you configured in ZappySys Data Gateway
   DSN=ZappySysGatewayDSN

   SELECT * FROM Campaigns

   DSN=ZappySysGatewayDSN

   

4. Read the data the same way we discussed at the beginning of this article.

5. That's it!

Now you can connect to Mailchimp data in Microsoft Fabric via the Data Gateway.
