The hosted Supabase Platform supports the [`pg_cron` extension](/docs/guides/database/extensions/pgcron), a simple cron-based job scheduler for PostgreSQL that runs inside the database.

In combination with the [`pg_net` extension](/docs/guides/database/extensions/pgnet), this allows us to invoke Edge Functions periodically on a set schedule.

## Examples

### Invoke an Edge Function every minute

Make a POST request to a Supabase Edge Function every minute:

```sql
select
  cron.schedule(
    'invoke-function-every-minute',
    '* * * * *', -- every minute
    $$
    select
      net.http_post(
          url:='https://project-ref.supabase.co/functions/v1/function-name',
          headers:='{"Content-Type": "application/json", "Authorization": "Bearer YOUR_ANON_KEY"}'::jsonb,
          body:=concat('{"time": "', now(), '"}')::jsonb
      ) as request_id;
    $$
  );
```
