Connect to Talkdesk Data in RapidMiner

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

Connect to Talkdesk in RapidMiner as a JDBC Data Source

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

1. Add a new database driver for Talkdesk: 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:talkdesk:
   

4. Enter the path to the cdata.jdbc.talkdesk.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class:

   
   cdata.jdbc.talkdesk.TalkdeskDriver
   

   
6. Create a new Talkdesk connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Talkdesk driver you configured previously.
9. Enter your connection string in the Host box.

   Talkdesk uses the OAuth 2.0 Client Credentials grant. There is no browser-based authorization step and no callback URL.

   Set the following connection properties:

   • AccountName: The name of your Talkdesk account.
   • Region: The region where your Talkdesk instance is deployed. Supported values are US (default), EU, CA, AU, UK, and FedRamp.
   • OAuthClientId: The Client Id assigned when you registered your custom OAuth application.
   • OAuthClientSecret: The Client Secret assigned to your custom OAuth application.

   Creating a Custom OAuth Application

   1. Log in to your Talkdesk account and select OAuth Clients from the navigation menu.
   2. Click Create OAuth Client and give the client a descriptive name.
   3. Set Grant Type to Client Credentials.
   4. Click Add scopes and select the scopes for the data you want to access.
   5. Click Create and copy the Client Id and Client Secret.

   When you connect, the driver automatically requests an access token from Talkdesk, caches it, and refreshes it when it expires. Make sure the scopes selected for the application match the views you plan to query, or the token request can fail.

   Built-in Connection String Designer

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

   
   java -jar cdata.jdbc.talkdesk.jar
   

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

   

   A typical connection string is below:

   
   AccountName=myAccount;Region=US;OAuthClientId=myClientId;OAuthClientSecret=myClientSecret;
   

10. Enter your username and password if necessary.

You can now use your Talkdesk connection with the various RapidMiner operators in your process. To retrieve Talkdesk 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 Talkdesk data.
