# Upsert Contact

`POST /v1/contacts`

Create a contact, or update the matching one if it already exists.

The contact is matched inside your organization on `email` first, then
on `linkedin_url` (both normalized), so re-sending the same person is
safe and returns the same `id`. Fields you send overwrite the stored
values; fields you omit are left untouched. `201` is returned for both
the create and the update.

`company_domain` is what links the contact to an account — the account
(and its company) is created when it does not exist yet, and
`company_name` is only used for that creation. Sending `company_name`
alone does not link an account.

Requires the `contacts:write` scope on the API key.
