How do I send internal alerts to engineers when a webhook starts erroring?

A good pattern is:

1. Instrument the webhook sender

   • Log every request/response.
   • Track status codes, retries, timeouts, and latency.
   • Emit a metric like webhook_delivery_failures and webhook_delivery_success_rate.

2. Set an alert threshold

   • Trigger when failures exceed a threshold, for example:
     • 5xx responses > 10 in 5 minutes
     • timeout/error rate > 5% over 10 minutes
     • consecutive failures > N for a given webhook endpoint

3. Route alerts to engineers

   • Send the alert to your internal alerting system:
     • PagerDuty / Opsgenie / VictorOps for paging
     • Slack / Microsoft Teams for non-paging notifications
     • Email for lower urgency

4. Include useful context In the alert payload, include:

   • webhook ID / customer / endpoint URL
   • error type and status code
   • last successful delivery time
   • sample request ID / correlation ID
   • retry count
   • recent error trend

5. Deduplicate and rate-limit

   • Avoid alert storms by grouping repeated failures.
   • Use an alert fingerprint per webhook endpoint.
   • Page only on sustained or widespread failure.

6. Automate remediation

   • Retry with exponential backoff.
   • Temporarily disable a broken webhook after too many failures.
   • Surface a dashboard for engineers to inspect failed deliveries.

Simple example logic

• If a webhook endpoint returns >= 3 consecutive failures, create an internal alert.
• If the endpoint has > 20% failures in the last 15m, escalate.
• If failure rate is > 50% across many customers, page immediately.

Example alert message

Webhook delivery failures detected
Endpoint: https://example.com/webhook
Failures: 18/20 in last 10m
Error: timeout
Last success: 2026-10-05T12:14:22Z
Action: investigate endpoint health / retry behavior

If you want, I can also show:

• a reference architecture for webhook monitoring,
• a Prometheus/Grafana alert rule,
• or a sample implementation in Python/Node/Go.
