Can a change on character sheet change trigger an API?

I have done a little digging...it seems like it can but not sure since I have not had any luck. So I am trying to determine in the on('change event gets trigger from a character sheet? I am working with the Pathfinder Second Edition sheet and I cannot seem to get this right. I would like to trigger an API script is changes are made. But I am still pretty new at this. I have a very simple script just to see...I have tried strength, STR and few others but it never triggers? on('change:strength_score', function(obj, prev) {     console.log(obj);     console.log(prev); }); in the end I would like to get to the  repeating_conditions  section to look for changes. I am not sure I can do this?

Your code looks like it is using a mix of character sheet sheet worker code and API scripyt code. There are differences between them. In the API, you need to do something more like on('change:attribute', function(obj, prev) {     console.log(obj);     console.log(prev); }); You then need to find out which attribute changed, on which character.

Great this works! Thank you...
