Enable the CData JDBC Driver for PayPal in KNIME

Use standard data access components in KNIME to create charts and reports with PayPal data.

One of the strengths of the CData JDBC Driver for PayPal is its cross-platform support, enabling integration with major BI tools. Follow the procedure below to access PayPal data in KNIME and to create a chart from PayPal data using the report designer.

Define a New JDBC Connection to PayPal Data

  1. If you have not already done so, install the Report Designer extension: Click File -> Install KNIME Extensions, and filter on "Report".
  2. In a new workflow, click File -> Preferences and expand the KNIME -> Database Driver nodes to add cdata.jdbc.paypal.jar. The driver JAR is located in the lib subfolder of the installation directory.
  3. In the Node Repository view, expand the Database node and drag a Database Reader onto the workflow editor.
  4. Double-click the Database Reader and set the following properties:

    • Database Driver: In the menu, select the CData JDBC driver.
    • Database URL: Enter the connection properties. The JDBC URL begins with jdbc:paypal: and is followed by a semicolon-separated list of connection properties.

      The provider surfaces tables from two PayPal APIs. The APIs use different authentication methods.

      • The REST API uses the OAuth standard. To authenticate to the REST API, you will need to set the OAuthClientId, OAuthClientSecret, and CallbackURL properties.
      • The Classic API requires Signature API credentials. To authenticate to the Classic API, you will need to obtain an API username, password, and signature.

      See the "Getting Started" chapter of the help documentation for a guide to obtaining the necessary API credentials.

      To select the API you want to work with, you can set the Schema property to REST or SOAP. By default the SOAP schema will be used.

      For testing purposes you can set UseSandbox to true and use sandbox credentials.

      A typical JDBC URL is below. jdbc:paypal:Schema=SOAP;Username=sandbox-facilitator_api1.test.com;Password=xyz123;Signature=zx2127;

    • User Name: The username used to authenticate.
    • Password: The password used to authenticate.
    • SQL Statement: Enter an SQL query in the SQL Statement box or double-click a table. This article uses the query below to create a chart: SELECT Date, GrossAmount FROM Transactions
  5. Test the connection by clicking Fetch Metadata.

  6. Connect the Database Reader to a Data to Report node to supply the dataset to a range of data visualization controls. Click Execute and then click Edit Report at the top of the workflow to open the report designer perspective.
  7. You can now generate reports based on live data. To create a chart, drag the chart control from the palette to the report designer. In the resulting wizard, you can use the filtering and aggregation controls available in KNIME.
