Use Case

Webhook retries hide incidents until data is already wrong

Track webhook processing completion with explicit ping checks.

What breaks when this goes silent

Retries and DLQs help recovery, but teams still need fast detection when webhook pipelines degrade.

  • Webhooks fail asynchronously without immediate visibility
  • Delivery success != processing success
  • Downstream breakage surfaces too late
How it works

Step 1

Ping success only after webhook processing completes

Step 2

Ping fail on terminal processing errors

Step 3

Alert on missing completions for critical topics

Copy and ship

Webhook handler completion ping

app.post('/webhook', async (req, res) => {
  try {
    await processWebhook(req.body);
    await fetch('https://silentfail.dev/api/ping/YOUR_TOKEN/success', { method: 'POST' });
    res.sendStatus(200);
  } catch (e) {
    await fetch('https://silentfail.dev/api/ping/YOUR_TOKEN/fail', { method: 'POST' });
    res.sendStatus(500);
  }
});
