M2E Pro migration to Item Spec 4.0

Modified on Sun, 12 Feb 2023 at 01:14 PM

In 2021, Walmart announced the end of support for Item Spec 3.2 and introduced a new Item Spec 4.0. Walmart Item Spec 4.0 is an updated version of the API designed to make product setup and maintenance easier for anyone who sells items on Walmart.com. 

The new API includes more than 250 new and optimized attribute names, accompanied by extended data definitions, more specific closed list values, and better organization of attributes.

Third-party API-based apps such as M2E Pro were due to move to the new Item Spec iteration by October 1, 2022. As always, we did our best to stay in line with the latest e-commerce updates and completed the migration to Item Spec 4.0 within the deadline.

With the migration, some changes were made in the extension. For example, you may have noticed that the Walmart subcategories are now missing from the extension.

To ensure seamless Magento Walmart synchronization, please follow these three easy steps:

1. Update your marketplaces

Go to Walmart integration > Configuration > Marketplaces and hit Update All.

2. Create new Category Policies

Go to Walmart integration > Configuration > Policies > Add Policy and select Category Policy.


3. Assign new Category Policies to your items

In your M2E Pro Listing switch the Settings View Mode, tick products, and select Use Another Category Policy in the ‘Actions’ drop-down.

By doing this, you can be sure that your M2E Pro is fully utilizing Walmart's new Item Spec and that your online business is benefiting from increased discovery and better product placement on Walmart.com.
