How to Get Push Notifications for Supabase Database Events

Your Supabase database is the source of truth for your app. When data changes — a new user signs up, an order is placed, a record is deleted — you should know about it immediately.

Why monitor Supabase database events?

Supabase database webhooks let you react to data changes in real time. But unless you build a custom notification system, those events just fire into the void. Hook Bell bridges the gap — every INSERT, UPDATE, or DELETE becomes a push notification on your phone.

Supported events

• INSERT — "New user signed up: john@example.com"
• UPDATE — "User updated: jane@acme.co"
• DELETE — "Record deleted from users table"

You choose which tables and operations to monitor. Hook Bell parses the payload and delivers a human-readable notification.

How to set it up

1. 1. Create a connection — In Hook Bell, create a new connection for Supabase and copy the webhook URL.
2. 2. Configure Supabase webhooks — In your Supabase project, go to Database → Webhooks. Create a new webhook trigger, select the table and events (INSERT, UPDATE, DELETE), and paste the Hook Bell URL.
3. 3. Monitor your data — Every time the selected table changes, you'll get a push notification with the event type and relevant details.
