Subscription Expiration

The platform automatically converts expired subscriptions to free plans. To enable this:

2. Set up cron job: Choose one of the following options:

   Option A: Vercel Cron (Recommended for Vercel deployments)

   • Add to vercel.json:

   {
     "crons": [{
       "path": "/api/cron/check-subscriptions",
       "schedule": "0 * * * *"
     }]
   }

   • Set environment variable: CRON_SECRET (optional, for security)

   Option B: External Cron Service

   • Set up a cron job to call: GET https://your-domain.com/api/cron/check-subscriptions
   • Include header: Authorization: Bearer YOUR_CRON_SECRET (if CRON_SECRET is set)
   • Recommended schedule: Every hour (0 * * * *)

   Option C: Supabase pg_cron (If enabled)

   • Uncomment the pg_cron section in the migration file
   • The function will run automatically every hour

3. Environment Variables:

   • CRON_SECRET (optional): Secret token for securing the cron endpoint
