Best pattern for idempotent Stripe webhooks in Supabase Edge Functions?

Question

I gate side-effects on checkout.session.completed but worry about duplicate delivery. How do you dedupe — a processed_events table, or rely on unique constraints?

DevFAS · Answer

update: went with the processed_events table — added a unique index on event_id and insert-on-conflict-do-nothing at the top. zero dupes since. thanks both!
