You call wmissuerefund. Because of runtime validation, you know that any refund amount or transaction ID returned by this MCP Server is structured correctly and won't break downstream systems.

Secure Order Cancellation and Acknowledgment

When an order status needs adjustment, you call `wm_acknowledge_order` to confirm the purchase moves into processing. If a customer cancels, use `wm_cancel_order` to safely restrict those variables. Because of Pydantic validation, if the API sends back malformed data for these actions, your agent fails loudly—you never get silent corruption.

Manage Shipping and Refunds Correctly

To close out an order, you execute `wm_ship_order_lines` to update tracking. If a refund is necessary, run `wm_issue_refund`. Both tools require specific input data. Pydantic ensures that the parameters passed to these critical functions are 100% correct before execution.

Comprehensive Fulfillment Checks

You can check for issues by running `wm_get_unshipped_orders` or fetching returns using `wm_get_return_requests`. After checking, you might generate labels with `wm_download_shipping_labels`. The validation layer makes sure the output of every MCP Server call fits your expected schema.
