Hi @tbailey,
I am still unsure of what needs to be “fixed.” As we have covered, the Contacts API call successfully created this contact in HubSpot with the “Affliliate” Lead source value.
The Contacts API is not an automatic two-way sync, so I cannot speak to why a specific record does not exist in your database. You can pull contacts from HubSpot to populate an external database with this endpoint, but that is separate from the method which created the contact above.
