stripe radar early fraud warning webhook never fired

TL;DR

Early fraud warnings only fire for enrolled card networks on live payments, and only when an issuer actually reports fraud, so no events may simply mean no warnings were issued. Confirm the webhook endpoint subscribes to radar.earlyfraudwarning.created and that recent deliveries show no failures. Check the Dashboard Radar warnings feed; if warnings appear there but not at your endpoint, the problem is delivery, not generation.

Use this when

• You expect early fraud warnings and none arrive at your endpoint.
• The warnings feed in the Dashboard shows entries your system never saw.
• You are setting up early fraud warning handling for the first time.

Not for this skill when

• You are testing in test mode. Early fraud warnings are live-only.
• No warnings exist in the Dashboard feed either. There is nothing to deliver.
• Other webhook events are also missing. Fix the endpoint itself first.

Steps

1. In Dashboard webhook settings, confirm the endpoint subscribes to radar.earlyfraudwarning.created. Verify: the event type is listed on the endpoint.
2. Check the endpoint's recent delivery log for failures or retries. Verify: recent attempts show 2xx responses.
3. Open the Radar early fraud warnings feed in the Dashboard. Verify: whether any warnings exist for your recent payments.
4. If warnings exist in the feed but never reached your endpoint, re-check the signing secret and URL for that endpoint. Verify: a redelivery attempt succeeds.
5. Document that warnings are rare and network-dependent, so your handler must tolerate long gaps. Verify: your system does not alert on absence alone.

Variant phrasings

Shorter phrasing.

Alternate word order.

no radar.earlyfraudwarning.created events

Event-name phrasing.

Compatibility: Stripe Radar; early fraud warnings are live-mode and network-dependent. Webhook deliveries require a reachable HTTPS endpoint.

Why it happens

Early fraud warnings depend on issuers reporting fraud through the card networks, which only some networks and issuers do, and only on live traffic. Teams often wire up the handler, see nothing for weeks, and assume it is broken, when the pipeline is healthy and quiet.

Edge cases / pitfalls

• Do not treat a quiet warnings feed as a health signal for Radar overall. It is a sparse, best-effort feed.
• Endpoint signing secrets rotate. A stale secret silently fails every delivery.
• Warnings can arrive days after the payment. Your handler must match them to old payments, not just recent ones.
