A custom function is a software code that can be used to automate a process and this allows you to automate a notification, call a webhook, or perform logic immediately after a workflow rule is triggered. This feature helps to automate complex tasks and calculations.

This will help in integrating Zoho Projects with other Zoho Apps & third party applications.
