Briefing
The only change this week is an announcement about new enum values in the Merchant Fulfillment API for Germany‑based domestic shipments. It won’t break existing integrations today, but if your code validates the DeliveryExperience or DeliveryExperienceOption fields strictly, you could start receiving 400‑type errors once Amazon begins returning the new values on Oct 1 2026, potentially halting order fulfillment and costing you revenue.
Announcement
Amazon is adding two new options—DeliveryConfirmationWithIdentityCheck and DeliveryConfirmationWithNameVerification—to the DeliveryExperience and DeliveryExperienceOption fields of the getEligibleShipmentServices and createShipment endpoints for the German store, effective Oct 1 2026. Update any request‑building code, schema validation, or enum‑mapping logic that assumes a closed set of values for these fields; a quick grep for DeliveryExperience or DeliveryExperienceOption in your codebase will reveal where you need to add the new constants.
