Mailchimp Connector for SAP Crystal Reports Read / write MailChimp Campaigns, Lists, Members, Reports and more in without coding. In this article you will learn how to quickly and efficiently integrate Mailchimp data in SAP Crystal Reports without coding. We will use high-performance Mailchimp Connector to easily connect to Mailchimp and then access the data inside SAP Crystal Reports. Let's follow the steps below to see how we can accomplish that! Download Documentation Mailchimp Connector for SAP Crystal Reports is based on ZappySys API Driver which is part of ODBC PowerPack. It is a collection of high-performance ODBC drivers that enable you to integrate data in SQL Server, SSIS, a programming language, or any other ODBC-compatible application. ODBC PowerPack supports various file formats, sources and destinations, including REST/SOAP API, SFTP/FTP, storage services, and plain files, to mention a few.

Create ODBC Data Source (DSN) based on ZappySys API Driver

Step-by-step instructions

To get data from Mailchimp using SAP Crystal Reports we first need to create a DSN (Data Source) which will access data from Mailchimp. We will later be able to read data using SAP Crystal Reports. Perform these steps:

1. Download and install ODBC PowerPack.

2. Open ODBC Data Sources (x64):

   

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

   ZappySys API Driver

   
   • Create and use User DSN if the client application is run under a User Account. This is an ideal option in design-time, when developing a solution, e.g. in Visual Studio 2019. Use it for both type of applications - 64-bit and 32-bit.
   • Create and use System DSN if the client application is launched under a System Account, e.g. as a Windows Service. Usually, this is an ideal option to use in a production environment. Use ODBC Data Source Administrator (32-bit), instead of 64-bit version, if Windows Service is a 32-bit application.

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. 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 how to get and use 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:

   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!

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

   MailchimpDSN

   Mailchimp

   OAuth [OAuth]

   https://[$DataCenter$].api.mailchimp.com

   Required Parameters
   Data Center	Fill-in the parameter...
   Client Id	Fill-in the parameter...
   Client Secret	Fill-in the parameter...
   Default List Id	Fill-in the parameter...
   Optional Parameters
   RetryMode	RetryWhenStatusCodeMatch
   RetryStatusCodeList	429
   RetryCountMax	5
   RetryMultiplyWaitTime	True

   

    ApiKey Auth [Http]

   Steps how to get and use 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)::

   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!

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

   MailchimpDSN

   Mailchimp

   ApiKey Auth [Http]

   https://[$DataCenter$].api.mailchimp.com

   Required Parameters
   Api Key	Fill-in the parameter...
   Default List Id	Fill-in the parameter...
   Optional Parameters
   Data Center
   RetryMode	RetryWhenStatusCodeMatch
   RetryStatusCodeList	429
   RetryCountMax	5
   RetryMultiplyWaitTime	True

   

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:

   Read / write MailChimp Campaigns, Lists, Members, Reports and more in without coding.

   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 SAP Crystal Reports 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 SAP Crystal Reports:

   

   ZappySys API Driver - Mailchimp

   Read / write MailChimp Campaigns, Lists, Members, Reports and more in without coding.

   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.
