# Put somebody on an inbox

Adds one account to the people on a number or a mailbox, which lets them read its private threads and send from it. Idempotent — 201 when the row is new, 204 when they were already on it — and 409 when the account holds no seat in this workspace. An admin for any inbox; the owner for their own connected mailbox or Zoom line.

Access class: `workspace`.
