Get a Mac notification when a row is inserted in Supabase

Supabase database webhooks post the new, old and changed rows of a table to a URL. A hook per table turns sign-ups, orders or any insert into a notification and a count.

Needs: the free EventBar app on your Mac, an EventBar account, and a Supabase account with permission to add webhooks. About five minutes. Generic JSON.

Steps

Create the webhook URL. In the EventBar dashboard, open the Webhooks tab, pick the group this belongs to (one group per site or app is the usual shape), choose the provider Generic JSON, name it, and press Create. Copy the URL; it stays visible and can be rotated any time.
Paste it into Supabase. In Supabase: Database, then Webhooks, then Create a new hook. Table your table, events Insert, type HTTP Request, method POST, URL your hook URL. Create the EventBar hook as Generic JSON with default type named after the table, for example new_profile.
Trigger one. Most services offer a test delivery; otherwise do the real thing once. It shows up in the dashboard's Events tab within a second and in the menu bar, as an undefined type named after the event. That first one is your proof the wiring works.
Make it read well. Press Define on the new type and give it a title and a body template. Fields come from the payload, nested ones with dots. The table below is a starting point.

What you'll see

Type	Title	Body template
`new_profile`	New profile	`{record.email}`
`new_order`	New order	`{record.total} from {record.customer_id}`

Every type has its own switch in the menu bar, so a noisy one can be quiet on this Mac and still counted. Counts cover the last hour, 24 hours, 7 days, 30 days and all time.

Worth knowing

The payload's type is INSERT, UPDATE or DELETE; set it as the type field instead if one hook should cover all three on a table.
Don't put personal data in templates you'd rather not see on a lock screen. An id is usually enough.
Supabase can add HTTP headers to the request, which means the API with a key works here too; the hook URL is simply less to configure.

The full contract, including how each preset reads a payload and what the answers mean, is in the API docs. Something about Supabase's payload changed? Tell us and we'll fix the guide.
