Walmart DSV is currently in the process of transitioning from digital signature-based API authentication to a token-based one. We have made some updates to accommodate this change. If the necessary Admin setting is enabled for your account, you will see a new checkbox on the Walmart DSV General company settings called Enable Access Token Based Authentication. When you enable this, five new fields related to Access Token will appear, as well as two actions to Get New Access Token and Validate API Access Token. Note that both authentication types will be functional until March 2024. However, to obtain your Consumer ID and Private key for Walmart, you must contact their support team directly. You will only have access to your Client ID and Client Secret, used for the new Token-Based authentication.
