Contact owners manage specific contacts in Apollo.
Use the Update Contact Owner for Multiple Contacts endpoint to assign multiple contacts to a different user in your team's Apollo account.
To update more than the contact's owner, such as job titles or contact details, use the Update a Contact endpoint instead.
