Create workflow triggers with custom functions and update data.

Using Custom Function in Zoho Desk

Custom functions are easy to program scripts, which helps you to update the data in related help desk modules or other third-party applications. When a record matches the workflow criteria, workflow engine automatically triggers the custom function and update the records. With custom functions, you can program custom scripts using the Deluge Script (powered by Deluge, Zoho's proprietary language), associate them to workflow rules, and automate the business process.
