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 reminder before a trial expires, then cancel the job if the customer upgrades early.

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",
    "body": {
      "event": "trial.ends_soon",
      "delay": "7 days before trial end",
      "customerId": "cus_123"
    },
    "idempotencyKey": "trial.ends_soon-cus_123-2026-05-15"
  }'

Failed payment recovery

Trigger follow-up attempts after a failed invoice without putting billing recovery inside a polling cron.

Event: invoice.payment_failed
Delay: 1 hour, 24 hours, 3 days

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/invoice.payment_failed",
    "runAt": "2026-05-15T09:00:00.000Z",
    "body": {
      "event": "invoice.payment_failed",
      "delay": "1 hour, 24 hours, 3 days",
      "customerId": "cus_123"
    },
    "idempotencyKey": "invoice.payment_failed-cus_123-2026-05-15"
  }'

Onboarding follow-up

Send product nudges after signup while keeping each delayed callback visible and cancellable.

Event: user.signed_up
Delay: 15 minutes, 1 day, 3 days

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/user.signed_up",
    "runAt": "2026-05-15T09:00:00.000Z",
    "body": {
      "event": "user.signed_up",
      "delay": "15 minutes, 1 day, 3 days",
      "customerId": "cus_123"
    },
    "idempotencyKey": "user.signed_up-cus_123-2026-05-15"
  }'

Renewal reminder

Notify a customer before subscription renewal without adding another internal worker.

Event: subscription.renews_soon
Delay: 14 days before renewal

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/subscription.renews_soon",
    "runAt": "2026-05-15T09:00:00.000Z",
    "body": {
      "event": "subscription.renews_soon",
      "delay": "14 days before renewal",
      "customerId": "cus_123"
    },
    "idempotencyKey": "subscription.renews_soon-cus_123-2026-05-15"
  }'

  -H "Authorization: Bearer wh_live_xxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://api.example.com/webhooks/customer.updated",

    "body": {
      "event": "customer.updated",
      "delay": "10 minutes",
      "customerId": "cus_123"
    },
    "idempotencyKey": "customer.updated-cus_123-2026-05-15"
  }'

Abandoned signup cleanup

Run cleanup or reactivation logic when a signup remains incomplete after a fixed window.

Event: signup.abandoned

curl https://webhookscheduler.com/api/v1/schedule \
  -H "Authorization: Bearer wh_live_xxxxx" \
  -H "Content-Type: application/json" \

  }'

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.
