How to read Mailchimp data in ZappySys Data Gateway?

In this section we will learn how to configure and use Mailchimp Connector in the API Driver to extract data from the Mailchimp.

Create Data Source in ZappySys Data Gateway based on ZappySys API Driver

Download and install ZappySys ODBC PowerPack.
Search for gateway in start menu and Open ZappySys Data Gateway:
Go to Users Tab to add our first Gateway user. Click Add; we will give it a name tdsuser and enter password you like to give. Check Admin option and click OK to save. We will use these details later when we create linked server:
Now we are ready to add a data source. Click Add, give data source a name (Copy this name somewhere, we will need it later) and then select Native - ZappySys API Driver. Finally, click OK. And it will create the Data Set for it and open the ZS driver UI.

MailchimpDSN
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:

Now it's time to configure the Connection Manager. Select Authentication Type, e.g. Token Authentication. Then select API Base URL (in most cases, the default one is the right one). More info is available in the Authentication section.

OAuth [OAuth]

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

Navigate to the Registered Apps page in your Mailchimp account.
Click Register An App.
Fill out the Register An App form.
Click Create.
After successfully registering your application, you'll see the client_id and client_secret at the bottom of the page - record these values and store them securely.
Record your Mailchimp data center, since we will need it later. The data center will be 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".
Back at the connector screen, enter the data center that was recorded in step 6 into the Data Center field.
Enter the client_id value that was recorded in step 5 into the Client Id field.
Enter the client_secret value that was recorded in step 5 into the Client Secret field.
Click Generate Token. If proper authentication occurs, you will see a notice saying so. If you get any errors, click Yes on the dialog box and then a large browser window will launch - log into your Mailchimp account here and approve the use of the application.
Select the Test Connection button at the bottom of the window to verify proper connectivity with your Mailchimp account.
If the connection test succeeds, select OK.

Fill in all required parameters and set optional parameters if needed:

ApiKey Auth [Http]

Steps to get Mailchimp Credentials
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)::

Log into your Mailchimp account.
Navigate to the API Keys section of your Mailchimp account: https://admin.mailchimp.com/account/api/
In the Your API keys section of the page, click Create New Key.
Give your new key a descriptive name that will remind you which application it's used for.
Copy the generated 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.)
Record your Mailchimp data center, since we will need it later. The data center will be 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".
Back at the connector screen, enter the data center that was recorded in step 6 into the Data Center field.
Enter the API key that was recorded in step 5 into the Api Key field.
Select the Test Connection button at the bottom of the window to verify proper connectivity with your Mailchimp account.
If the connection test succeeds, select OK.

Fill in all required parameters and set optional parameters if needed:

Once the data source has been configured, you can preview data. Select the Preview tab and use settings similar to the following to preview data:
Click OK to finish creating the data source.

Reading data from client application

Firstly, to get data from ODBC data source based on ZappySys ODBC driver, in your client application, you would need to connect to ODBC source and then from the list select the data source.
Finally, to read the data just read tables/views in your app or enter a SQL statement to extract data, e.g.:
SELECT * FROM Campaigns
