Journey-native webhooks use the flat sanitized payload (api_version: "2026-08-17"). Deduplicate on event_id. Money is integer cents. Name slugs and template_display_name neutrally. landing_url and referrer_url follow the Attribution Passthrough validation and sanitization rules.

| Journey Checkout Started | Patient entered checkout. | Per checkout start |
| Journey Completed | Intake finished for this journey. Deduplicate deliveries on event_id. Per-patient aggregation is a separate business rule, not delivery idempotency. | Per journey |
