Zoho CRM continues to evolve toward faster, smarter, and more interactive user experiences. One of the most awaited enhancements is finally here – Client Script support for Custom Buttons.
This feature allows you to execute client-side JavaScript logic instantly when a user clicks a custom button, without relying on server-side workflows, Deluge functions, or page reloads.
For Zoho One users and CRM administrators, this opens a new dimension of real-time UI automation, better performance, and guided user actions.
What’s New: Client Script Support for Custom Buttons
By attaching a Client Script to a custom button, you can now:
- Execute logic instantly based on record context
- Modify UI elements dynamically
- Collect user input before proceeding
- Prevent incorrect actions with confirmations
- Reduce dependency on backend automation
This support is live across all Zoho data centers.
What Are Custom Buttons in Zoho CRM?
Custom Buttons allow you to extend Zoho CRM functionality by triggering predefined actions such as:
- Opening URLs
- Invoking functions
- Updating records
- Launching scripts
With the new update, Client Scripts can now be attached directly to Custom Buttons, enabling instant execution within the browser.
