Updating Default Token from API - How?

I'm working on an API script that scale characters (their health, damage, etc) up and down, and reached the point where I was trying to update the default token, but _defaulttoken is a read-only field.  Is there not any way to do this from the API? The Roll20 Enhancement Suite is a chrome extension that can do this, so I have to imagine there is a  way, but poking araound that extension didn't immediately reveal anything, though granted I'm not terribly familiar with typescript. Update: upon further inspection, it looks like R20ES calls the same webpage function as actually installing a new default token, so I don't believe that's an option after all.

You use the setDefaultTokenForCharacter( characterObject, tokenObject ) function: setDefaultTokenForCharacter(repChar,token); Note that there is bug right now where the token bars preferences don't get saved.

Thanks!

Note that you're passing the Character Object, not the character ID.&nbsp; And the Token Object.&nbsp; Here's the original announcement for the function:&nbsp; <a href="https://app.roll20.net/forum/permalink/3862777/" rel="nofollow">https://app.roll20.net/forum/permalink/3862777/</a>
