Administrators and the account owner only.

An inbox channel belongs to at most one profile. Binding one that another profile already covers returns 422 carrying conflicting_business_hour_id, inbox_id, and channel in place of the usual errors object, and the whole write is rolled back.

Under calendar_24_7 the server stores schedule and schedule_type as null whatever the payload carries.

Omitted keys keep their stored value and an explicit null is ignored rather than clearing the field. Sending inbox_channels replaces the whole set.

Personal access token only. The API supports a second, partner-issued token class that is not part of the public surface. This endpoint does not accept that class.
