Platform Webhook Handler Troubleshooting

Webhook endpoint: https://dev.webhook.sebek.io/webhooks/notion?tenantId=jason

Health Checks

• /health
• /health/vault
• /internal/events/recent

Critical Requirements for Notion

• Public DNS must resolve this host from the public internet.
• TLS cert must be publicly trusted (e.g. Let's Encrypt), not private CA.
• Request must pass Notion signature verification or shared-secret fallback.

Quick CLI Tests

nslookup dev.webhook.sebek.io 1.1.1.1
curl -I https://dev.webhook.sebek.io/health
curl -s https://dev.webhook.sebek.io/internal/events/recent
kubectl -n dev logs deploy/platform-webhook-handler -f

Expected Success Signals

• New timestamp appears in /internal/events/recent immediately after button click.
• Webhook logs show inbound request with Notion request ID.
• New agent-* pod appears in the target namespace.
