云途物流 & 燕文物流 Shipping

Scope and boundaries

Do not request Shopify login or use Shopify APIs. This skill operates only against YunExpress and Yanwen APIs.
Use it for carrier-side work only: checking parcels, orders, channels, warehouses, rates, charges, tracking, labels, and preparing carrier orders. Do not use it to register carrier accounts, manage a Shopify store, fulfill orders automatically, or make customs/address decisions for the merchant.

The supplied OMS specification includes a UAT address and test account. A test credential may return real, accurate quotation results, but it is not a substitute for the merchant's own credentials and must never be embedded, disclosed, or used for creating operational shipments.
Read operations may run after a connection check. Any operation that creates, changes, cancels, deletes, intercepts, registers/disables IOSS, changes subscriptions, or submits CPSC data needs an explicit user approval immediately before --execute.
Do not call user registration; direct account creation, frozen-account, product-permission, and billing issues to the relevant carrier.

Ask the merchant to obtain their own credentials:
