Updated Contact and Properties were Deleted



I am testing updating contacts via the contacts API. While I was testing I shot over bad json and it appears in doing so it deleted all the associated custom properties. Why would it do this, how do I set a property field up to prevent this behavior. This seems like terrible system design and I'd like to understand why it was allowed to happen and how to prevent it.


Hi @jlg,

Can you give me more information on what exactly happened? To dig into this further, I'll need:

  1. Your Hub ID
  2. The specific contact record you're referring to
  3. The bad json request body you sent to HubSpot
