Automate your issues workflow using Custom Functions. A custom function is a piece of code that can be used for automating a process. You can write your own function in Deluge and call it from one or more business rules. It is similar to the built-in functions in Javascript like DATE, CONCAT, REPLACE, etc. In Zoho Projects, you can update the issue fields automatically using Workflow rules. With the help of custom functions, you can automate a notification, call a webhook, or perform logic right after a Workflow rule is triggered.

Benefits:

• When an issue is escalated, user can be notified via an SMS, an email or a Zoho Chat using custom functions.
• When an issue's severity is updated, a relevant comment can be added to the issue via a custom function.
• Integration can be done with Zoho Apps and third party apps using a custom function.
