**Stop contact's sequence** · Deletes or overwrites data

Stop one prospect's email sequence: no further steps are sent and the prospect is marked manually-paused, keeping it and its history in the campaign. Use remove_prospect_from_campaign to delete it instead, or delete_campaign to end a whole campaign. Confirm with the user before calling. prospectId comes from get_prospects or add_prospect_to_campaign. Stopping never refunds anything. Returns stopped: true and the prospectId, or HTTP 404 when the prospect is not on this account.
