API Scripting Functionality

Hello Roll20 Staff, Lately I have been implementing macros, using TokenMod, to streamline combat in my games (DND 5e). I am using an API script to operate a macro that shows a creature's AC and movement speed when I hover over the token. The problem I am having is that this tooltip is visible to everyone. I do see that there is a " GM only " box next to " Show " in the token settings. However, it seems that the " GM Only " checkbox is not exposed to the Roll20 API. None of the scripts I use can seem to check or uncheck that specific box. Considering that the " GM Only " checkbox was added in February of 2025, I was wondering if there are plans to implement its functionality in the Roll20 API? It undermines the convenience of the macro if I have to open each token individually and manually check " GM Only ". I am fairly new to using macros and API scripting so if I am misunderstanding the functionality please let me know.  Thanks for your time.

Doesn't this work for you?  !token-mod --on gm_only_tooltip It works for me with TokenMod v0.8.88 GM Chair said: However, it seems that the " GM Only " checkbox is not exposed to the Roll20 API. 

I forgot to include the first underscore between "gm" and "only". I can't believe I missed that! Thanks so much for your help.

When checking API documentation, it's usually a good idea to check both the Help Center and the Wiki. The documentation of recentish objects are spotty.

That's great advice, thank you! I will keep both of those resources handy in the future.
