Plaid JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Plaid account data including Assets, Investments, Liabilities, Transactions, and more!



Integrate Plaid data with standard components and data source configuration wizards in RapidMiner Studio.

This article shows how you can easily integrate the CData JDBC driver for Plaid into your processes in RapidMiner. This article uses the CData JDBC Driver for Plaid to transfer Plaid data to a process in RapidMiner.

Connect to Plaid in RapidMiner as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Plaid:

  1. Add a new database driver for Plaid: Click Connections -> Manage Database Drivers.
  2. In the resulting wizard, click the Add button and enter a name for the connection.
  3. Enter the prefix for the JDBC URL: jdbc:plaid:
  4. Enter the path to the cdata.jdbc.plaid.jar file, located in the lib subfolder of the installation directory.
  5. Enter the driver class: cdata.jdbc.plaid.PlaidDriver
  6. Create a new Plaid connection: Click Connections -> Manage Database Connections.
  7. Enter a name for your connection.
  8. For Database System, select the Plaid driver you configured previously.
  9. Enter your connection string in the Host box.

    You can connect to Plaid using the embedded OAuth connectivity. When you connect, the Plaid OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

    Optionally set the Account Id property to return data related to a specific Account.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.plaid.jar

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

    A typical connection string is below:

    AccountId=123456789;InitiateOAuth=GETANDREFRESH
  10. Enter your username and password if necessary.

You can now use your Plaid connection with the various RapidMiner operators in your process. To retrieve Plaid data, drag the Retrieve operator from the Operators view. With the Retrieve operator selected, you can then define which table to retrieve in the Parameters view by clicking the folder icon next to the "repository entry." In the resulting Repository Browser, you can expand your connection node to select the desired example set.

Finally, wire the output to the Retrieve process to a result, and run the process to see the Plaid data.
