PayPal JDBC Driver

Easy-to-use PayPal client enables Java-based applications to easily consume PayPal Transactions, Orders, Sales, Invoices, etc.



Access and process PayPal data in Apache NiFi using the CData JDBC Driver.

Apache NiFi supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic. When paired with the CData JDBC Driver for PayPal, NiFi can work with live PayPal data. This article describes how to connect to and query PayPal data from an Apache NiFi Flow.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live PayPal data. When you issue complex SQL queries to PayPal, the driver pushes supported SQL operations, like filters and aggregations, directly to PayPal 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 PayPal data using native data types.

Connecting to PayPal Data in Apache NiFi

  1. Download the CData JDBC Driver for PayPal installer, unzip the package, and run the JAR file to install the driver.
  2. Copy the CData JDBC Driver JAR file (and license file if it exists), cdata.jdbc.paypal.jar (and cdata.jdbc.paypal.lic), to the Apache NiFi lib subfolder, for example, C:\nifi-1.3.0-bin\nifi-1.3.0\lib.

    On Windows, the default location for the CData JDBC Driver is C:\Program Files\CData\CData JDBC Driver for PayPal.

  3. Start Apache NiFi. For example:

    cd C:\nifi-1.3.0-bin\nifi-1.3.0\bin
    run-nifi.bat
    
  4. Navigate to the Apache NiFi UI in your web browser: typically http://localhost:8080/nifi
  5. Click the (Configuration) button from the Operate sidebar.
  6. In the NiFi Flow Configuration page, navigate to the Controller Services tab.
  7. Click the button to create a new controller service.
  8. In the Add Controller Service page, select DBCPConnection Pool, and then click Add.
  9. Click the gear button to configure the new DBCPConnection Pool.
  10. In the Configure Controller Service page, navigate to the Properties tab. Fill in the properties:

    PropertyValue
    Database Connection URLjdbc:paypal:Schema=SOAP;Username=sandbox-facilitator_api1.test.com;Password=xyz123;Signature=zx2127;InitiateOAuth=GETANDREFRESH
    Database Driver Class Namecdata.jdbc.paypal.PayPalDriver

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.paypal.jar

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

    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.

  11. Click the button to enable the new DBCPConnection Pool.

Your PayPal data is now available for use in Apache NiFi. For example, you can use the DBCPConnection Pool as the source for a QueryDatabaseTable processor.
