Feed Gumroad Data into FineReport

The CData JDBC Driver for Gumroad fully implements the JDBC standard and can provide Gumroad data connectivity to a wide variety of BI, reporting, and ETL tools and custom applications. In this article, we explain how to set Gumroad data as JDBC data source in FineReport and view Gumroad data as a table in the Report Designer.

Set Up a JDBC Data Source of Gumroad Data

Follow the instruction below to set Gumroad data as a FineReport database connection.

1. Copy the cdata.jdbc.api.jar file from the lib folder in the CData JDBC Driver for Gumroad installation directory to the lib folder of the FineReport installation directory. You will need to copy the cdata.jdbc.api.lic file as well.
2. From the Server tab, select Define Data Connection, click to add a new connection, and click JDBC.

Next we will set up the data connection definition in the window.

1. Database: Others
2. JDBC Driver: cdata.jdbc.api.APIDriver
3. URL: A standard JDBC connection string using semicolon-separated connection properties.

   Using OAuth Authentication

   To authenticate to Gumroad and connect to your own data or to allow other users to connect to their data, you can use the OAuth 2.0 standard. This is the recommended authentication method.

   First you need to register an OAuth application with Gumroad. You can create an OAuth application by visiting your Gumroad account settings at https://app.gumroad.com/settings/advanced and navigating to the Applications section.

   After setting the following connection properties, you are ready to connect:

   • AuthScheme: Set this to OAuth.
   • InitiateOAuth: Set this to GETANDREFRESH. The CData API Profile for Gumroad will automatically walk through the OAuth process in order to obtain the access token.
   • OAuthClientID: Set this to the client_id that is specified in your app settings.
   • OAuthClientSecret: Set this to the client_secret that is specified in your app settings.
   • CallbackURL: Set this to the Redirect URI you specified in your app settings.

   Example connection string

   Profile=C:\profiles\Gumroad.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;
   

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.api.jar
   

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

   

   When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

   A typical JDBC URL is below:

       jdbc:api:Profile=C:\profiles\Gumroad.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;
     


4. Click Connection pool attributes and set Test before getting connections to No.

Click Test connection to ensure you have configured the connection properly. With the connection to Gumroad set up, you can use it as FineReport data source.

Select Gumroad Data in the Report Designer.

1. Click to add a new template data set and select DB query to open the database query window.

2. Choose the JDBC connection that you created from the dropdown list.
3. The Gumroad entities will appear as tables on the left pane.
4. Write a SELECT statement for the Gumroad data tables and columns that you want to load.

5. Click preview and data is shown as table.

With these simple steps, Gumroad can be used as a JDBC data source in FineReport.
