The hosted Supabase Platform supports the [`pg_cron` extension](/docs/guides/database/extensions/pgcron), a recurring job scheduler in Postgres.
|
|
|
|
In combination with the [`pg_net` extension](/docs/guides/database/extensions/pgnet), this allows us to invoke Edge Functions periodically on a set schedule.
|
|
|
|
<Admonition type="caution">
|
|
|
|
To access the auth token securely for your Edge Function call, we recommend storing them in [Supabase Vault](/docs/guides/database/vault).

## Examples
|
|
|
|
### Invoke an Edge Function every minute
|
|
|
|
Store `project_url` and `publishable_key` in Supabase Vault:
|
|
|
|
```sql
|
|
select vault.create_secret('https://project-ref.supabase.co', 'project_url');
|
|
select vault.create_secret('YOUR_SUPABASE_PUBLISHABLE_KEY', 'publishable_key');
|
|
```
|
|
|
|
Make a POST request to a Supabase Edge Function every minute:
|
|
|
|
```sql
|
|
select
|
|
cron.schedule(
|
|
'invoke-function-every-minute',
|
|
'* * * * *', -- every minute
|
|
$$
|
|
select
|
|
net.http_post(
|
|
url:= (select decrypted_secret from vault.decrypted_secrets where name = 'project_url') || '/functions/v1/function-name',
|
|
headers:=jsonb_build_object(
|
|
'Content-type', 'application/json',
|
|
'Authorization', 'Bearer ' || (select decrypted_secret from vault.decrypted_secrets where name = 'publishable_key')
|
|
),
|
|
body:=concat('{"time": "', now(), '"}')::jsonb
|
|
) as request_id;
|
|
$$
|
|
);
|
|
```
