Mailchimp Connector for Azure Data Factory (SSIS) How to Make Generic API Request

Prerequisites

Before we begin, make sure the following prerequisites are met:

SSIS designer installed. Sometimes it is referred as BIDS or SSDT (download it from Microsoft).
Basic knowledge of SSIS package development using Microsoft SQL Server Integration Services.
ODBC PowerPack is installed (if you are new to SSIS PowerPack, then get started!).

Make Generic API Request in SSIS

Begin with opening Visual Studio and Create a New Project.
Select Integration Service Project and in new project window set the appropriate name and location for project. And click OK.

In the new SSIS project screen you will find the following:
- SSIS ToolBox on left side bar
- Solution Explorer and Property Window on right bar
- Control flow, data flow, event Handlers, Package Explorer in tab windows
- Connection Manager Window in the bottom
Note: If you don't see ZappySys SSIS PowerPack Task or Components in SSIS Toolbox, please refer to this help link.
Now, Drag and Drop SSIS Data Flow Task from SSIS Toolbox. Double click on the Data Flow Task to see Data Flow designer.
From the SSIS toolbox drag and API Source (Predefined Templates) on the data flow designer surface, and double click on it to edit it:
Select New Connection to create a new connection:
Use a preinstalled Mailchimp Connector from Popular Connector List or press Search Online radio button to download Mailchimp Connector. Once downloaded simply use it in the configuration:

Mailchimp

Now it's time to configure authentication. Firstly, configure authentication settings in Mailchimp service and then proceed by configuring API Connection Manager. Start by expanding an authentication type:

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:

Login into your Mailchimp account, click on your Profile Icon, and hit Account & billing:
Navigate to the Registered Apps page in your Mailchimp account:
Click Register An App button:
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.
After successfully registering your application, you'll see the Client ID and Client Secret, record these values and store them securely:
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.
Now go to SSIS package or ODBC data source OAuth authentication configuration.
Proceed by entering the data center into the Data Center field that was recorded in the previous step.
Then enter the Client ID value into the Client ID field that you recorded in the previous step.
Enter the Client Secret value into the Client Secret field that was recorded in the previous step.
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.
Finally, hit 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.
Done! Now you can use Mailchimp Connector!

API Connection Manager configuration

Just perform these simple steps to finish authentication configuration:

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

Login into your Mailchimp account, click on your Profile Icon, and hit Account & billing:
Navigate to the API keys page in your Mailchimp account:
In the Your API keys section of the page, click Create A Key button:
Give your new key a descriptive name that will remind you which application it's used for:
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):
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.
Now go to SSIS package or ODBC data source ApiKey Auth authentication configuration.
Proceed by entering the data center into the Data Center field that was recorded in the previous step.
Then enter the API key into the Api Key field that you copied earlier.
Finally, click the Test Connection button at the bottom of the window to verify proper connectivity with your Mailchimp account.
Done! Now you can use Mailchimp Connector!

API Connection Manager configuration

Just perform these simple steps to finish authentication configuration:

Set Authentication Type to ApiKey Auth [Http]
