Webhook events — Billing is based on webhook events admitted to the platform. Each inbound event counts once regardless of how many delivery attempts or retries occur.
Retries — Retries are included in all plans and are not billed separately. Retry behaviour is bounded by the configured retry policy. Delivery attempt counts are visible as operational telemetry for debugging but do not drive billing.
Overage block size — 1 block = 25,000 additional events. Overage is triggered only when event count exceeds your plan limit.
Overage block pricing — Starter: €15 / block · Core: €12 / block · Scale: €10 / block. Blocks are billed at the end of the billing period based on actual event usage above your plan limit.
Production activation is gated to keep identity and billing aligned.
