Access Klipfolio Data in Mule Applications Using the CData JDBC Driver

The CData API Driver for JDBC connects Klipfolio data to Mule applications enabling read functionality with familiar SQL queries. The JDBC Driver allows users to easily create Mule applications to backup, transform, report, and analyze Klipfolio data.

This article demonstrates how to use the CData API Driver for JDBC inside of a Mule project to create a Web interface for Klipfolio data. The application created allows you to request Klipfolio data using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any CData JDBC Driver to create a Web interface for the hundreds of available data sources.

1. Create a new Mule Project in Anypoint Studio.
2. Add an HTTP Connector to the Message Flow.
3. Configure the address for the HTTP Connector. 👁 Add and Configure the HTTP Connector
   
4. Add a Database Select Connector to the same flow, after the HTTP Connector.
5. Create a new Connection (or edit an existing one) and configure the properties.
   • Set Connection to "Generic Connection"
   • Select the CData JDBC Driver JAR file in the Required Libraries section (e.g. cdata.jdbc.api.jar). 👁 Adding the JAR file (Salesforce is shown).
     
   • Set the URL to the connection string for Klipfolio

     Start by setting the Profile connection property to the location of the Klipfolio Profile on disk (e.g. C:\profiles\Klipfolio.apip). Next, set the ProfileSettings connection property to the connection string for Klipfolio (see below).

     Klipfolio API Profile Settings

     In order to authenticate to Klipfolio, you'll need to provide your API Key. You can generate an API key from the Klipfolio Dashboard app through either the My Profile page or from Users if you are an administrator (you must have the user.manage permission). Set the API Key in the ProfileSettings property to connect.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Klipfolio 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.

   • Set the Driver class name to cdata.jdbc.api.APIDriver. 👁 A configured Database Connection (Salesforce is shown).
     
   • Click Test Connection.
6. Set the SQL Query Text to a SQL query to request Klipfolio data. For example:

   SELECT Id, Name FROM DataSources WHERE IsDynamic = 'true'

   👁 Configure the Select object (Salesforce is Shown)
   
7. Add a Transform Message Component to the flow.
8. Set the Output script to the following to convert the payload to JSON:

   %dw 2.0
   output application/json
   ---
   payload
    

   👁 Add the Transform Message Component to the Flow
   
9. To view your Klipfolio data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The Klipfolio data is available as JSON in your Web browser and any other tools capable of consuming JSON endpoints.

At this point, you have a simple Web interface for working with Klipfolio data (as JSON data) in custom apps and a wide variety of BI, reporting, and ETL tools. Download a free, 30 day trial of the JDBC Driver for Klipfolio and see the CData difference in your Mule Applications today.
