Delayed webhook API

A delayed webhook API for HTTP jobs that should run later.

When your app needs to call an endpoint in the future, Webhook Scheduler gives you one API call for the delayed job and one dashboard for monitoring, retries, cancellation, and debugging.

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/webhooks/follow-up",
    "method": "POST",
    "runAt": "2026-05-21T09:00:00.000Z",
    "body": {
      "event": "trial.follow_up",
      "workspaceId": "ws_123"
    },
    "idempotencyKey": "trial_follow_up:ws_123:2026-05-21"
  }'

Future HTTP delivery

Schedule a public HTTPS request for seconds, minutes, days, or months from now depending on your plan.

Retry and cancellation

Cancel pending jobs before they fire and let failed deliveries recover with visible retry attempts.

Dashboard-first operations

Inspect queued jobs, delivery attempts, response bodies, status codes, latency, and endpoint trends.

What is a delayed webhook API?

A delayed webhook API lets your backend create an HTTP request that should execute later. You send the target URL, method, payload, headers, and run time; the platform stores the job and dispatches it when it becomes due.

It is useful when the unit of work is not arbitrary compute, but a future callback to another system.

Where it fits better than cron

Cron is good for fixed server-owned schedules. A delayed webhook API is better when every user, invoice, trial, workspace, or integration needs its own future HTTP delivery.

If you are comparing options, read the cron job alternative page.

Use cases for delayed webhooks

Common workflows include trial follow-ups, subscription grace periods, invoice recovery, onboarding reminders, delayed CRM syncs, webhook retries, and post-signup automations.

For the broader scheduling concept, see scheduled webhooks.

Production behavior developers expect

A production delayed webhook API needs more than a timestamp in a database. It needs idempotency, URL safety checks, retry state, delivery attempts, response storage, dashboard search, rate limits, and cancellation.

Webhook Scheduler keeps those operations visible while your product owns the business workflow.

FAQ

Can I schedule any HTTP request for later?

You can schedule public HTTPS targets with supported HTTP methods, JSON payloads, and safe custom headers. Unsafe destinations such as localhost and private networks are blocked.

Is this the same as a queue?

No. Queues are best for internal background compute. Webhook Scheduler is focused on future outbound HTTPS deliveries with retries, logs, cancellation, and dashboard visibility.

Can delayed webhooks retry automatically?

Yes. Failed deliveries can retry according to plan limits, and each attempt remains visible for debugging.

Ship delayed webhooks without maintaining queue infrastructure.

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