Templates

SaaS webhook workflows you should not run from cron.

Use these as implementation shapes for delayed billing, onboarding, renewal, and cleanup events. The point is not the cURL. The point is making the workflow visible, retryable, and safe.

Trial Ending Reminder

Schedule a webhook when a trial starts, then send a reminder before conversion day.

Event
trial.ends_soon
Delay
7 days before trial end
curl https://webhookscheduler.com/api/v1/schedule \
  -H "Authorization: Bearer wh_live_xxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://api.example.com/webhooks/trial.ends_soon",
    "runAt": "2026-05-15T09:00:00.000Z",

      "event": "trial.ends_soon",
      "delay": "7 days before trial end",

  }'

We built Webhook Scheduler for this exact use case. Start with the API docs, then compare pricing against the cost of maintaining queue workers, retry tables, delivery logs, and support tooling yourself.
