Build Klaviyo-Connected Apps in Choreo

The Choreo platform from WS02 is a versatile platform designed for low-code and cloud-native engineering. Developers, even those without advanced coding skills, can leverage Choreo's user-friendly low-code environment to simplify application development. When combined with CData Connect AI, users gain immediate cloud-to-cloud access to Klaviyo data for applications. This article details the process of connecting to Klaviyo using Connect AI and building an application with real-time access to Klaviyo data within Choreo.

CData Connect AI delivers a pure cloud-to-cloud interface for Klaviyo, enabling you to construct applications within Choreo that utilize live Klaviyo data data, all without the need for data replication to a natively supported database. With its built-in optimized data processing capabilities, CData Connect AI efficiently directs all supported SQL operations, including filters and JOINs, directly to Klaviyo, capitalizing on server-side processing to swiftly provide the requested Klaviyo data.

Configure Klaviyo Connectivity for Choreo

Connectivity to Klaviyo from Choreo is made possible through CData Connect AI. To work with Klaviyo data from Choreo, we start by creating and configuring a Klaviyo connection.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "Klaviyo" from the Add Connection panel

3. Enter the necessary authentication properties to connect to Klaviyo.

   To authenticate to Klaviyo, provide an API Key. You can generate or view your API keys under 'My Account'

   1. Navigate to 'Settings' > 'API Keys'
   2. Click 'Create API Key'.
   3. Name your API key and choose the desired scopes.

   To connect in your CData solutions, set API Key to your Klaviyo API key.

   If you wish to use OAuth authentication, refer to the Help documenation.

4. Click Save & Test
5. Navigate to the Permissions tab in the Add Klaviyo Connection page and update the User-based permissions.

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to Klaviyo data from Choreo.

Connect to Klaviyo from Choreo

The steps below outline connecting to CData Connect AI from Choreo to create a new application with access to live Klaviyo data.

Creating a Construct

1. Sign in to the Choreo platform. Note: This article is from the perspective of an Anonymous user.
2. Select Components from the left sidebar and then click +Create. Next, choose Manual Trigger and then Start from scratch.
3. Give the manual trigger a Name and Description and click Create.
4. After the trigger is created, click on Edit Code.
5. The Ballerina Low-Code IDE is displayed. Choreo automatically generates a construct in the low-code diagram view. Delete this construct by highlighting it and clicking on the trashcan icon.
6. Click the + icon towards the top of the screen and select Main from the Add Constructs toolbar on the right. In the following Function Configuration form, click Save.

Adding the CData Connect AI Connector

1. Click the + icon between the Start and End ellipses and click Connector.

2. In the Connectors sidebar on the right, search for "CData". Click CData Connect to open the Connector settings pane.

3. In the Connector settings pane, enter the configuration settings:
   • Enter an Endpoint Name for your use. In this example, we use "connectEndpoint".
   • In the User field, enter the email address of the CData Connect AI user, wrapped in quotation marks (for example, "[email protected]").
   • In the Password field, enter the PAT you generated earlier, wrapped in quotation marks (for example, "SampleToken").

4. After clicking Save, the low-code editor appears with the CData Connect AI logo.

Adding a Query Action

1. Click the + icon between the new and end shapes, select Action, and then select our existing connector endpoint.

2. Select query for the connector Operation. There is now an Action pane on the right.

3. Enter a SQL query to retrieve Klaviyo data as the sqlQuery parameter for the query. For example:

   			SELECT * FROM Klaviyo1.Klaviyo.Campaigns LIMIT 10
   		

   • When writing the query, be sure to specify the Connection Name as the catalog and Data Source Name as the schema. For example, Klaviyo1.Klaviyo.
   • These parameters appear on the Connections page of your CData Connect AI dashboard.

Iterating over Klaviyo Data

1. Click the Show Source icon in the top right of the code editor.
2. Add an import statment to import the ballerina/io library:

   		
   		import ballerina/io;
   	

3. Next, add a from statement after the query action to iterate through the results of the SQL query:

		
		check from record{} result in resultStream
		do {
			io:println("Full Campaigns details: ", result);
		};
	

4. The code for the construct will now look similar to this:

			
			import ballerinax/cdata.connect;
			import ballerinax/cdata.connect.driver as _;
			import ballerina/io;

			public function main() returns error? {
				connect:Client connectEp = check new (user = "connect_cloud_username", password="connect_cloud_pat");

				stream<record {}, error=""?> resultStream =
				connectEp->query(sqlQuery = `SELECT * FROM Klaviyo1.Klaviyo.Campaigns LIMIT 10`);

				check from record{} result in resultStream
				do {
					io:println("Full Campaigns details: ", result);
				};
			}
		

5. Click Save to save the action. The diagram should now look similar to this:

Deploying the Program

Once you have added all of your desired actions to your program, follow these steps:

1. Commit and push your final source code in the web editor and sync those changes with the Choreo platform.
2. Click Deploy in the left navigation bar of the Choreo Console.
3. Under Build Area, click Configure & Deploy to deploy your program.
4. When prompted, enter the same CData Connect AI username and password that you used earlier and click Deploy.

You have now created an application with access to live Klaviyo data in Choreo.
