# Create contact

  - `platform` 'instagram' | 'facebook' | 'telegram' | 'twitter' | 'bluesky' | 'reddit' | 'whatsapp' | 'slack' | 'sms' — Channel platform. Only the enum values support contact channels; any other platform is rejected with code platform_not_supported.
  - `platformIdentifier` string
  - `displayIdentifier` string

## Response `200`

## Other responses

- `400` — Invalid request. Channel fields are all-or-nothing: accountId, platform and platformIdentifier must be sent together (code: missing_required_field). A platform outside the enum does not support contact channels (code: platform_not_supported, details.supportedPlatforms lists the valid values).
- `401` — Unauthorized
- `409` — Duplicate channel. The platformIdentifier is already bound to a channel on this accountId.
