How do I fetch data from Vtiger using the Code Editor?

For complex data handling, a code editor is available to write scripts in JavaScript. This allows for data transformation before being displayed in Vtiger. The editor supports HTTP calls to external applications and fetching Vtiger data.
Once the configuration is done, you can test the connection using the Test button next to the Code Editor. You can:

• Use the Response tab to view the response of the API call
• Use the Log tab for debugging.
• Use the log function for debugging purposes.
