How to Build a Webhook Monitoring and Event Log Dashboard for SaaS Teams

Webhooks are the connective tissue of modern SaaS infrastructure. When Stripe processes a payment, a webhook fires to update your database. When a customer signs a contract in DocuSign, a webhook triggers the provisioning workflow. When a trial expires, a webhook kicks off the downgrade sequence. Each of these events is critical to your business operations — and each one can fail silently.

Most SaaS teams find out about webhook failures from customer complaints. The payment processed but the account wasn't upgraded. The contract was signed but provisioning didn't run. A webhook monitoring dashboard gives your ops and engineering teams visibility into event delivery health before customers are affected.

Why webhook failures are a silent ops risk

The failure modes for webhooks are varied. The receiving endpoint returns a 5xx error and the webhook provider retries — sometimes for hours before giving up. The endpoint succeeds (returns 200) but the processing logic throws an exception silently. The event is delivered but arrives out of order and overwrites newer state. The destination service is rate-limited and drops events under load.

Stripe, for example, retries failed webhooks for up to 72 hours with exponential backoff. This means a webhook that started failing Friday evening may still be retrying Monday morning — with the receiving service returning errors the whole time. Without a monitoring dashboard, the first signal is a customer reporting their account is in the wrong state.

What to monitor: delivery status, latency, failure rates, and retry queues

The metrics that matter for a webhook monitoring dashboard:

Delivery success rate: What percentage of webhook events are being delivered successfully in the first attempt? A drop from 99% to 95% is a signal worth investigating immediately.

Retry queue depth: How many events are currently in a retry state? A growing queue means the receiving endpoint has been failing for long enough that retries are accumulating.

Latency by event type: How long between the originating event and successful delivery? Spikes in latency (even with eventual success) indicate processing bottlenecks.

Failure distribution by event type and source: Are all payment webhooks failing, or only subscription.updated events? Is the failure isolated to one webhook source or affecting all integrations?

Building an event log viewer for your ops team

Beyond aggregate metrics, your ops team needs a searchable event log: a record of every webhook received, its delivery status, the payload, and any error details. This is the tool that answers "what happened to account X's provisioning on Tuesday?" without needing an engineer to grep production logs.

A useful event log viewer has: search and filter by event type, account ID, timestamp range, and status; the full webhook payload (expandable, not just the summary); the processing status and any error messages from your handler; and a manual retry trigger for stuck events.

The manual retry trigger deserves special attention. When an event fails because of a transient downstream error (your CRM was briefly unavailable), your ops team should be able to trigger a retry directly from the dashboard rather than filing a ticket for engineering to run a database script.

Alerting and on-call workflows

The monitoring dashboard should integrate with your alerting system. Useful webhook-specific alerts: delivery success rate drops below 95% for any event type over a 5-minute window; retry queue depth exceeds a threshold; a specific event type has had zero successful deliveries in the past hour (indicating a complete processing outage for that event).

These alerts should route to whoever is responsible for integration health — typically an on-call engineer or ops lead. The alert should include enough context to diagnose quickly: which event type, how many failures, whether retries are succeeding or also failing, and a direct link to the relevant section of the event log.

When to build vs. use Hookdeck or Svix

Tools like Hookdeck and Svix provide managed webhook infrastructure: they receive events from providers, buffer them, and deliver them to your endpoints with built-in retry, logging, and a monitoring UI. For teams that want webhook reliability without building it, these are good options — typically $200–$500/month at meaningful scale.

The case for building your own monitoring layer: when you have multiple internal event systems beyond third-party webhooks (internal domain events, background job outcomes), when you need to correlate webhook events with internal database state, or when your ops team needs a unified view of all integration health rather than separate dashboards per provider. At that point, a custom event log that aggregates all event sources is more useful than a purpose-built webhook tool.
