Stream QuickBooks Online Data into Apache Kafka Topics

Apache Kafka is an open-source stream processing platform that is primarily used for building real-time data pipelines and event-driven applications. When paired with the CData JDBC Driver for QuickBooks Online, Kafka can work with live QuickBooks Online data. This article describes how to connect, access and stream QuickBooks Online data into Apache Kafka Topics and to start Confluent Control Center to help users secure, manage, and monitor the QuickBooks Online data received using Kafka infrastructure in the Confluent Platform.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live QuickBooks Online data. When you issue complex SQL queries to QuickBooks Online, the driver pushes supported SQL operations, like filters and aggregations, directly to QuickBooks Online and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze QuickBooks Online data using native data types.

Prerequisites

Before connecting the CData JDBC Driver for streaming QuickBooks Online data in Apache Kafka Topics, install and configure the following in the client Linux-based system.

1. Confluent Platform for Apache Kafka
2. Confluent Hub CLI Installation
3. Self-Managed Kafka JDBC Source Connector for Confluent Platform

Define a New JDBC Connection to QuickBooks Online data

1. Download CData JDBC Driver for QuickBooks Online on a Linux-based system
2. Follow the given instructions to create a new directory extract all the driver contents into it:
   1. Create a new directory named QuickBooks Online mkdir QuickBooksOnline
   2. Move the downloaded driver file (.zip) into this new directory mv QuickBooksOnlineJDBCDriver.zip QuickBooksOnline/
   3. Unzip the CData QuickBooksOnlineJDBCDriver contents into this new directory unzip QuickBooksOnlineJDBCDriver.zip
3. Open the QuickBooks Online directory and navigate to the lib folder ls cd lib/
4. Copy the contents of the lib folder of QuickBooks Online into the lib folder of Kafka Connect JDBC. Check the Kafka Connect JDBC folder contents to confirm that the cdata.jdbc.quickbooksonline.jar file is successfully copied into the lib folder cp * ../../confluent-7.5.0/share/confluent-hub-components/confluentinc-kafka-connect-jdbc/lib/ cd ../../confluent-7.5.0/share/confluent-hub-components/confluentinc-kafka-connect-jdbc/lib/
5. Install the CData QuickBooks Online JDBC driver license using the given command, followed by your Name and Email ID java -jar cdata.jdbc.quickbooksonline.jar -l
6. Enter the product key or "TRIAL" (In the scenarios of license expiry, please contact our CData Support team)
7. Start the Confluent local services using the command: confluent local services start

   This starts all the Confluent Services like Zookeeper, Kafka, Schema Registry, Kafka REST, Kafka CONNECT, ksqlDB and Control Center. You are now ready to use the CData JDBC driver for QuickBooks Online to stream messages using Kafka Connect Driver into Kafka Topics on ksqlDB.

8. Create the Kafka topics manually using a POST HTTP API Request: curl --location 'server_address:8083/connectors' --header 'Content-Type: application/json' --data '{ "name": "jdbc_source_cdata_quickbooksonline_01", "config": { "connector.class": "io.confluent.connect.jdbc.JdbcSourceConnector", "connection.url": "jdbc:quickbooksonline:; InitiateOAuth=GETANDREFRESH", "topic.prefix": "quickbooksonline-01-", "mode": "bulk" } }'

   Let us understand the fields used in the HTTP POST body (shown above):

   • connector.class: Specifies the Java class of the Kafka Connect connector to be used.
   • connection.url: The JDBC connection URL to connect with QuickBooks Online data.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the QuickBooks Online JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.quickbooksonline.jar

     Fill in the connection properties and copy the connection string to the clipboard.

     QuickBooks Online uses the OAuth authentication standard. OAuth requires the authenticating user to log in through the browser. To authenticate using OAuth, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can obtain your own by registering an app with Intuit. Additionally, if you want to connect to sandbox data, set UseSandbox to true.

     See the Getting Started chapter of the help documentation for a guide to using OAuth.

   • topic.prefix: A prefix that will be added to the Kafka topics created by the connector. It's set to "quickbooksonline-01-".
   • mode: Specifies the mode in which the connector operates. In this case, it's set to "bulk", which suggests that the connector is configured to perform bulk data transfer.

   This request adds all the tables/contents from QuickBooks Online as Kafka Topics.

   Note: The IP Address (server) to POST the request (shown above) is the Linux Network IP Address.

9. Run ksqlDB and list the topics. Use the commands: ksql list topics;
10. To view the data inside the topics, type the SQL Statement: PRINT topic FROM BEGINNING;

Connecting with the Confluent Control Center

To access the Confluent Control Center user interface, ensure to run the "confluent local services" as described in the above section and type http://<server address>:9021/clusters/ on your local browser.
