How to Monitor Payment Webhooks

A webhook is how your payment provider tells your system “this customer paid”. If it fails, you can take money and still not deliver. Monitoring webhooks is essential.

A webhook is an automated message a payment provider (or any service) sends to your server to report an event — most importantly, that a payment succeeded. Your fulfilment logic depends on it. When webhooks stop arriving, you can take money and fail to deliver.

How webhooks break

• Your endpoint returns an error (500) or times out.
• A signing/secret mismatch causes the provider's message to be rejected.
• Your endpoint URL changed and the provider still posts to the old one.
• Provider retries exhaust and the event is dropped.

What to monitor

1. Endpoint reachability — is your webhook route responding?
2. Receipt — are expected events arriving within a normal window?
3. Processing — does a received event turn into an order/entitlement?

Good practice

Always make webhook handling idempotent, log every event, and treat “no events received when events are expected” as an alert condition — not just “server is up”.

What ForgeGuard does

ForgeGuard monitors the webhook component of the revenue path alongside checkout and payment, using read-only checks, and surfaces missed confirmations as incidents.

Limitations

Provider-specific delivery guarantees vary. Monitoring reduces the window in which a missed webhook goes unnoticed; it cannot force a provider or network to deliver.
