Intelligence Webhooks Subscribe

Pro-tier feature (2026-08-28, AJ: "重有咩賺錢位" -> Webhook Pro專屬): push notifications instead of polling, for real Data Factory events -- see services/webhook_service.py's VALID_EVENT_TYPES for the exact list. Most are backed by a daily scheduled job that already ran for another reason (honest same-cadence delivery, never a fabricated "real-time" claim); recall_match (2026-09-14) is the first exception -- see backend/main.py's recall_alert_scan job, added specifically to back this event type. To watch a brand/product keyword for new recalls: event_type="recall_match", ticker="<your keyword>" (the ticker field doubles as the free-text keyword here -- see that event type's comment in webhook_service.py). Does NOT spend quota -- this is a management action, not a data read.
