Me and my crew use this API script on Roll20, it works great:
Thank you! This saved the game I ran today! Nothing else was working, so we were about to wing it with regular roll20 dice, while translating the results. That would've been a nightmare. This script worked like a charm, though Roll20 itself kept losing connection. Once the dice roller tool is updated, I think I'll keep both options on hand, just in case.
No problem. It has changed the game a ton for us. The new character sheet that works with it is amazing.
