How to connect JSON data obtained from Google Sheets API with Data Connections

[Tomokazu Yamada]

I would like to make display Forms checklist items by accessing a simple database.

It shows item dynamically.

To achieve this, it is known that JSM's Data Connection function is used to obtain JSON data.

When creating JSON data, I tried accessing the data using the Google Sheets API, but I was unable to successfully retrieve the Excel values from the Data Connection page. (*See image)

Then, I checked the following page as a solution for this case, but I cannot implement the answer.

Is this because the version change ?

Is the reason I can't run it because it's the free version?
If I use the paid version, will I be able to run it?

We are currently testing the functionality and plan to use the paid version internally in the near future.

Thanks in advance.
