# Renewal reminders with Bark

> Configure scheduled Bark push notifications for upcoming subscription renewals.

# Renewal reminders with Bark

Subscription Manager can send renewal reminders through Bark. The hosted reminder flow uses a Netlify Scheduled Function and Supabase-backed notification settings.

## What users configure

Users configure Bark settings in the app:

* Bark server URL.
* Bark device key.
* Reminder timing.
* Per-subscription notification toggle.

## Required hosted services

* Supabase for notification settings and subscriptions.
* Netlify Functions for scheduled checks.
* Bark official server or a self-hosted Bark server.

## Required environment variables

```bash theme={null}
VITE_SUPABASE_URL=
VITE_SUPABASE_ANON_KEY=
SUPABASE_SECRET_KEY=
```

The legacy `SUPABASE_SERVICE_ROLE_KEY` name remains supported as an alias.

## SQL setup

Notification tables and constraints are included in the Supabase migrations. For current deployments, use:

```text theme={null}
supabase/migrations/20260615000100_baseline.sql
supabase/migrations/20260615000200_harden_existing_schema.sql
```

Older setup notes and legacy migration files are kept in `supabase/legacy/`.

## Scheduled function

The scheduled function lives at:

```text theme={null}
netlify/functions/send-scheduled-notifications.ts
```

It checks eligible subscriptions, sends Bark messages, records delivery history, and avoids duplicate sends.

## Local testing

```bash theme={null}
npm run test:notifications
```

Use Netlify Dev when testing the full function runtime:

```bash theme={null}
npm run dev:full
```
