Update but don't Create


Hi, I am trying to update a group of contacts. But if the contacts don’t exist in the database, I don’t want to create them.

The reason of this issue is: we deleted some contacts from hubspot for various reasons before, but when we use Get All Engagements to get certain info so that we can update a certain property, some deleted users’ engagements are still there. So when we update this specific property, those deleted users’ engagements will be inside our update body and these users’ accounts will be created again.

Is it possible for us to update old contacts but not create new contacts?
Or maybe we can work on deleting those engagements from the users we deleted?

Thank you so much!
