I am going to use the API to create Contacts and I want to assign the contacts I am creating to users. I am assuming that I have to populate the internal ID of the user into the HubSpotOwnerID field as part of the create API Put. How do I get that ID for the users?
@Roger_Parkinson Owners are in fact what you’re looking for for this. Any time you add a user to HubSpot, a corresponding owner is created for that user. You can get a list of all of your owners using this endpoint:
