API capability pack for bounded ShipStation API V2 operations against https://api.shipstation.com only. Enroll a ShipStation API-key connection named shipstation; no credential is embedded in the manifest. The pack reads shipments and rates, labels and tracking, fulfillments, inventory levels and inventory warehouses, shipping warehouses, purchase orders, suppliers, and carrier services. It bundles read-only fulfillment and inventory briefs plus approval-gated shipment creation, label purchase, and purchase-order receipt workflows. Label purchase, label void, shipment cancellation, and purchase-order receipt always require approval because they can incur charges, reverse fulfillment state, or change physical inventory. Shipment definitions remain explicit caller input and may use ShipStation's supported optional fields, including sales-order creation. The pack intentionally excludes carrier disconnect/funding, warehouse and supplier administration, batches, manifests, pickups, webhooks, tag and document mutation, bulk rate comparison, arbitrary label creation, arbitrary API passthrough, and credential-bearing arguments.
