Overview

Amazon has upgraded the Orders API v0 to include a new CompanyName attribute inside the ShippingAddress object across all marketplaces. The change, together with higher request‑rate limits for key order‑related endpoints, helps sellers capture business‑level buyer data and reduces throttling during high‑volume operations.

Key Points

• CompanyName attribute added — The ShippingAddress payload now returns the buyer’s corporate name (e.g., “Acme Manufacturing”), enabling precise invoicing for B2B orders.
• Universal rollout — The enhancement is live on every Amazon marketplace, from amazon.com to amazon.co.jp, so sellers with multi‑region catalogs see the same JSON structure everywhere.
• Increased rate limits — Amazon has raised the maximum calls per second for getOrder, getOrderAddress, and getOrderBuyerInfo, allowing more queries before a 429 response is returned.
• Backward‑compatible response — Existing integrations that ignore unknown fields continue to function because the new key is simply appended to the JSON object.
• Better data quality — Providing a dedicated company name reduces the need to parse free‑form address lines, cutting manual correction effort for corporate buyers.
• Enhanced reporting potential — Analytics tools can now pull the CompanyName field to segment sales by individual versus corporate customers, supporting more granular performance dashboards.

How the Updated Orders API v0 Works

1. Request order details — A GET request to /orders/v0/orders/{orderId} now returns a ShippingAddress object that includes CompanyName. Example: Querying order 112‑334‑556 yields "CompanyName":"GlobalTech Solutions" alongside street, city, and zip.
2. Retrieve address specifics — The /orders/v0/orders/{orderId}/address endpoint mirrors the enriched ShippingAddress structure. Example: A fulfillment script that previously extracted only AddressLine1 and City can now also pull CompanyName to print “GlobalTech Solutions” on the packing slip.
