supabase-webhooks-events

Implement Supabase database webhooks, pg_net async HTTP, LISTEN/NOTIFY, and Edge Function event handlers with signature verification. Use when setting up database webhooks for INSERT/UPDATE/DELETE events, sending HTTP requests from PostgreSQL triggers, handling Realtime postgres_changes as an event source, or building event-driven architectures. Trigger with phrases like "supabase webhook", "database events", "pg_net trigger", "supabase LISTEN NOTIFY", "webhook signature verify", "supabase event-driven", "supabase_functions.http_request".
