@KyleJepson I’ve watched your videos, read your posts and taken ALL of your warnings to heart. My use case for Custom Objects is actually the Car example so I’m 100% in. I have thought this out. A lot. A whole lot. That being said… should I mess up in the development of my API call - how difficult (read: expensive) would it be for me to correct or remove the Custom Object from my HubSpot? OR is there a testing sandbox I can play in before rolling out a finished version I’m confident will work for my team?
