Delete a channel this account owns
POST/api/sessions/:sessionId/channels/:channelId/delete
Irreversible, and every subscriber loses the channel. Deliberately NOT DELETE /channels/:channelId — that route unsubscribes, and the two must not be reachable by the same request with a slip of the wrist. Only the owner can delete.

Channel deleted
Session not started
The engine refused — not found, or this account does not own it
The session is not connected — an engine exists for it but is not ready: disconnected, reconnecting, or still initializing, so the request never reached WhatsApp. Wait for ready and retry. A session that was never started answers 400 instead, and the session lifecycle routes answer 409 for a conflicting state rather than this. One window answers this while the session still reads ready: WhatsApp Web periodically reloads its own page and the engine re-injects into it — for those few seconds the answer is a 409 naming the reload; retry shortly.
WhatsApp did not answer within the request budget — the operation may or may not have applied.
