MCS sandbox FAQs

  1. What is MCS API sandbox test data simulation?

MCS sandbox users can now create custom test data, in addition to retrieving non-customizable mock datasets provided by Walmart. Customize the test data in your MCS API sandbox according to your needs to quickly and easily simulate end to end flows before going live. These APIs allow you to simulate the MCS workflow such as setting up items, setting up sales channel, creating and cancelling customers order, and tracking the order status. 

  1. How do I get started and obtain my credentials for the MCS API Sandbox?

To get started, refer to Walmart Sandbox documentation for instructions on obtaining sandbox credentials.

  1. Can I test MCS Returns in MCS API Sandbox Environment with custom test data?

    The Multichannel Solutions (MCS) return order APIs are available in the sandbox environment. You can create, retrieve, and cancel return orders using custom test data without impacting production systems.

    The sandbox simulates the full return lifecycle, including the following statuses:

    • RETURN_INITIATED
    • RETURN_IN_TRANSIT
    • DELIVERED_AT_RETURN_CENTER
    • RETURN_RECEIVED

    Status progression is supported through both time-based and prefix-based simulation strategies.

    For more information on endpoints, request and response formats, and status simulation, refer to the MCS return order APIs.

  2. How long is my test data retained and when is it deleted?

All entity data in the MCS API Sandbox is retained for up to 2 days and automatically cleared afterward.
