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 BugTracker, you can update the issue fields automatically using business rules. With the help of custom functions, you can automate a notification, call a webhook, or perform logic right after a business rule is triggered.


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

  7. Click Save.
The manager wants to notify a set of users in the project about the change of bug owner for a specific bug upon escalation. The manager might have to send the notification very often to the same set of users on this subject in the future as well. The manager creates a custom function and get it called through one of the business rules.
