Replace one customer on a Discovery campaign's roster with another in one step: the first leaves at once and the replacement joins this month's calendar. Refused on a campaign that is not active or paused or is a one-time campaign whose run has finished, when the first is not on the roster, the replacement already is or cannot join, or while the campaign's first run is still choosing its customers. Returns when the replacement starts.

## Other responses

- `400`: The input, query, or Idempotency-Key is invalid.
- `401`: The bearer is missing, expired, or not accepted.
- `402`: Billing refused the write: the code names the reason and `details.reason` carries it.
- `403`: The credential lacks the operation's scope or role, or the operation needs a different door.
- `404`: The resource or organization does not exist for this caller.
- `405`: This path takes another HTTP method, named in `Allow`.
- `409`: The request conflicts with current state or with prior use of its Idempotency-Key.
- `413`: The request, or the answer it asks for, is too large; narrow it.
- `429`: The credential's rate budget is spent; retry after `Retry-After` seconds.
- `500`: An unexpected server failure; retry later. Only `request_id` identifies it.
- `503`: A dependency is temporarily unavailable; retry after `Retry-After` seconds.
- `default`: Another status a product answers for its own refusal (for example `415` for an unsupported attachment); branch on `code`.
