GET calls export purchase orders, inventory, item classes, attributes, cancellation requests, return requests and remittance/removed-item/content-match reports; PUT calls import items, inventory, pricing, ASNs, order cancellations, order adjustments (returns and refunds), order prep time and service-item configurations. Every operation is described by a published XSD. Authorization is an HMAC-SHA256 signature over "sellerId:emailaddress:timestamp" with a 30-minute timestamp validity.
