`PATCH /v1/mailboxes/{mailboxId}/audiences/{audienceId}/contacts/{contactId}`

## Request

- The document declares no server URL.
- Auth: one of:
  - OAuth 2 (authorization code, authorization URL `/authorize`, token URL `/oauth/token`, scopes: `email.write`)
  - HTTP bearer

Edit a contact, or unsubscribe them.

## Path parameters

- `mailboxId` string, required

## Request body

- ContactUpdate: A partial edit. `email` is absent on purpose — it is the contact's identity, so a change is delete-and-re-add rather than a patch. A name set to `null` is cleared; absent leaves it.
  - `firstName` string: Display names are capped at 200 characters.
  - `lastName` string: Display names are capped at 200 characters.
  - `unsubscribed` boolean
