Contacts, addressable by id or email — email wins when both are given.
Pass :audience_id to scope a call to an audience; omit it for the top-level
contact routes.
MillionSend.Contacts.create(%{audience_id: aud, email: "ada@acme.dev", first_name: "Ada"})
MillionSend.Contacts.get(%{audience_id: aud, email: "ada@acme.dev"})
MillionSend.Contacts.get("contact-uuid")
MillionSend.Contacts.update(%{id: id, unsubscribed: true, first_name: nil}) # nil clears

GET contacts. Accepts audience_id:, limit:, after:, before:.

PATCH /contacts/:id_or_email/topics — set per-topic subscriptions (always a
top-level route). params carries the address plus topics: as a list of
%{id: ..., subscription: :opt_in | :opt_out}.
