I needed to change settings on a Deal custom property so archived and deleted it but HS gives error when recreating. I have read that for CO one needs to purge the schema but not finding much about this case. Do I just need to wait?
Hey, @cyberwombat 
The DELETE endpoint “archives” (for 90 days then auto-purges) a property. One thing to try, is to go in-app to Setting > Properties > YOUR_OBJECT (Deals in this case) > Archived Properties tab and select permanently delete — Restore or permanently delete archived properties.

Yes I did that right away. it looks like one just has to wait a few hours for HS to purge after one deletes. I tried again today and it worked.
