What Amazon and Walmart Just Changed—And Why It Matters to You

These updates apply to both new and existing listings. That means even your best-selling SKUs could become unsearchable—or worse, unpurchasable—if they’re not updated to meet new requirements. Sellers without a solution are stuck in spreadsheet hell: reconfiguring templates, fixing validation errors, and re-uploading files. It’s time-consuming, frustrating, and prone to mistakes.

But it doesn’t have to be.

The New Rules of the Road

Here’s a breakdown of what each marketplace is doing—and why it matters.

🛒 Amazon SP-API

Amazon’s Selling Partner API brings big changes to product taxonomy. With 1,600+ new product types, each with its own set of required attributes, sellers must now reformat how they list and manage items.

If you don’t adapt, listings could disappear—or fail to publish at all.

The good news? There’s an opportunity in the upgrade. SP-API allows for:

• Near real-time inventory syncing
• Improved listing accuracy
• Better reporting and integration with tools like Zentail

🏬 Walmart Omnispec 5.0

Walmart’s update is all about granularity and standardisation. With more detailed product attributes and improved validation rules, listings are now cleaner, more accurate, and better optimised for Walmart’s search algorithm.In short: the better your data, the more likely your products are to show up and sell.
