AWS Lambda cron jobs

How to handle AWS Lambda cron jobs when schedules belong to your product

AWS Lambda cron jobs usually run through EventBridge schedules. That works well for fixed recurring tasks, but it gets awkward when your application needs one schedule per customer, subscription, or integration.

Where Lambda cron jobs fit well

If you need one nightly cleanup, one periodic billing audit, or one scheduled maintenance task shared by every account, AWS gives you a solid built-in path. EventBridge can trigger Lambda on a fixed cadence without keeping infrastructure alive.

That model assumes the schedule belongs to infrastructure. You define it once, wire it to a Lambda target, and update it when your deployment configuration changes.

Why dynamic schedules change the problem

Product teams often need schedules created from application data. A customer picks a report time, an integration sync runs at a plan-specific cadence, or your backend creates one recurring job for each tenant. Those schedules need lifecycle management from code.

Each account may need a different run time or timezone.
Your app needs to pause or update one schedule without touching the others.
The invoked endpoint often needs account-specific payloads or headers.
Support needs execution history for one failed recurring workflow.

The simpler pattern for app-owned schedules

Keep your business logic in an authenticated HTTP endpoint. Let your backend create a recurring webhook through CronCoco, then let CronCoco call that endpoint on schedule. That keeps schedules in your product data model instead of your AWS infrastructure config.

// api/run-report.ts
export async function POST(request: Request) {
  if (request.headers.get("x-cron-secret") !== process.env.CRON_SECRET) {
    return new Response("Unauthorized", { status: 401 });
  }
  const payload = await request.json().catch(() => ({}));
  await runReportForAccount(payload.accountId);
  return Response.json({ ok: true });
}

Create the recurring webhook from your backend

When a customer enables the workflow, your application can create the schedule through the CronCoco API and store the returned job id on the account or integration record.

curl -X POST https://api.croncoco.io/jobs \
  -H "Authorization: Bearer coco_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"account-report-acme","cron_expression":"0 14 * * 1-5","webhook_url":"https://api.your-app.com/run-report","headers":{"x-cron-secret":"YOUR_SECRET"},"payload":{"accountId":"acct_123"}}'

AWS EventBridge vs CronCoco

Fixed infrastructure-owned schedule: EventBridge and Lambda.
One recurring workflow per account or tenant: CronCoco.
Need schedule lifecycle controlled from your app backend: CronCoco.
Need payload-aware scheduled webhooks with execution visibility: CronCoco.

Where CronCoco fits

CronCoco is a better fit when Lambda should stay focused on application code and an external service should own schedule storage, webhook delivery, and run history. Your backend decides what schedules exist, and CronCoco handles the clock.
