Client Script provides us its collection of ZDK Client APIs and ZDK CRM APIs. The ZDK CRM APIs invoke the Zoho CRM APIs internally and so it accounts for API credits every time a ZDK Web API call is invoked. Below are some of the typical use cases of Client Script that can be accomplished using the ZDKs.

A. Instant form field validation

Client Script is a boon when you want your script to run as soon as the user updates the value of a field. For example, to show an error or an alert message based on any condition as soon as the user enters data on a field. For example, if you want the minimum Quantity of products to be 100, you can show an error whenever the user enters a value less than 100.


B. Auto-populate data based on your requirement or calculation

You can auto-populate data for fields whenever an event is triggered based on any criteria or populate data based on calculations. For example: Auto populate the field Request Name whenever a new record is created in the module Request.



C. Display custom messages

Using Client Script, you can display custom messages and alerts in Zoho CRM. For instance, if you want to display an alert when the user enters an age less than 18 or more than 80, you can create a Client Script on Create Page with onChange event type and use the  ZDK Client API, ZDK.Client.showAlert() in your script.


D. Accomplish data auto-correction

Using Client Script you can correct, update or modify data instantly after the user enters a value in a field. For example, consider that your organisation wants the name of the user to be entered in capital letters, you can create a Client Script on Create Page with onChange Field event type on the field First Name and write a script to auto-convert the name to Capital letters.
