Scheduled webhooks API

Schedule webhooks without building cron jobs or queues.

Webhook Scheduler lets your app create future HTTP deliveries with a simple API call. Use it for onboarding flows, billing reminders, delayed CRM syncs, follow-up events, and any workflow that should run later.

API request

HTTPS only

curl https://webhookscheduler.com/api/v1/schedule \
  -H "Authorization: Bearer wh_live_xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://api.example.com/webhook",
    "body": { "event": "trial.ends" },
    "runAt": "2026-05-15T09:00:00.000Z"
  }'

One API call

Send the target URL, payload, headers, and runAt timestamp. The job is queued and delivered at the right time.

Built for production

HTTPS-only destinations, SSRF protection, atomic worker claims, delivery logs, and status tracking are included.

No queue maintenance

Avoid running cron, Redis queues, custom workers, retry tables, and logging dashboards just to call an API later.

What are scheduled webhooks?

A scheduled webhook is an HTTP request your application asks a service to send in the future. Instead of executing immediately, the webhook is stored as a job, queued, and dispatched at the scheduled time.

This is useful when a product needs to trigger something later: trial expiration emails, billing reminders, delayed user syncs, follow-up automations, or cleanup tasks after an event.

Why not build it yourself?

The first version seems simple: save a timestamp and run a cron every minute. The production version is harder. You need retries, idempotency, observability, rate limits, security checks, stale lock recovery, and a way to inspect failed deliveries.

Webhook Scheduler packages that operational layer behind an API designed for SaaS products. You can focus on your product workflow instead of maintaining queue infrastructure.

Common use cases

Teams use scheduled webhooks when a future event needs to call another service: payment grace periods, onboarding reminders, subscription lifecycle events, delayed notifications, async CRM updates, and post-signup workflows.

If your system currently says “run this API call later,” this is the shape Webhook Scheduler is built for.

How it works

Create a job through the API, choose a public HTTPS target, add your payload, and set the execution time. The dashboard shows upcoming jobs, delivery attempts, statuses, latency, response body, and retry history.

FAQ

Can I schedule a webhook days or months in advance?

Yes. Paid plans support long scheduling windows, while the free plan is intentionally limited for sandbox usage.

Do scheduled webhooks retry automatically?

Yes. Failed deliveries can retry with plan-based recovery depth and delivery logs for every attempt.

Do you support private IP or localhost webhook targets?

No. Webhook Scheduler only dispatches to public HTTPS targets and blocks private, loopback, link-local, metadata, and unsafe destinations.

Ship delayed webhooks without maintaining queue infrastructure.

Start with the free plan, test a real delivery, then upgrade when the workflow becomes production critical.
