Requirement for JS API V1:
For V1, you should initialize the SDK present in the CDN URL before writing logic for the JS API tasks. Use the below method in the widget ZIP's JS file:

1. ZOHO.CREATOR.init()
2.         .then(function(data) {
3.           //Code goes here
4.         });

5. Points to Note

1. The tasks that can be performed from within the widget are limited to the ones pertaining to a version. For example, say you want to execute the JS API v2 Get Records task from within a widget. The records will be fetched only if you've provided the CDN URL pertaining to v2 in the widget's HTML file.
2. If you need to change the current JS API version, the following changes have to be done:
   
1. Change the CDN URL in the widget ZIP's HTML file to the required version
   
2. SDK initialization is required only for JS API v1. Add or remove the initialization method based on the required version, in the widget ZIP's JS file.
3. Update the syntax and configuration parameters of the JS API tasks to match those of the required version, in the widget ZIP's JS file.

The widget file needs to be re-uploaded afterwards. Keep in mind that after the CDN URL is updated, any tasks from the version used before will stop working.

1. Any changes to the JS script present in a widget's file will require re-uploading the modified file for the widget to work as required.
   
2. Make sure to provide the mandatory parameters necessary for a task in the configuration for successful execution.
3. Only Publish API tasks will work in published pages that can be accessed by people who do not hold a Creator account.
