When you publish or update listings, LitCommerce handles the data transfer through a feed, which represents the information transmitted from the tool to the marketplace.

Each time a feed is created, the following information is sent:

• Price.
• Quantity.
• Product details (new data or updates).

However, the Walmart API has certain limitations that may affect feed processing and how your listings are created or updated through LitCommerce. For more details, refer HERE.

This article outlines the key limitations. 

Only 10 feeds can be sent per hour

Whether you update a single product or a hundred, each time you click Publish to Walmart or Update to Walmart, one feed is generated.

We recommend completing edits for all necessary listings first and publishing or updating them in bulk rather than individually. This helps avoid exceeding the feed limit.

Each feed has a file size limit 

The file size limits (MB) vary depending on the type of feeds. Surpassing the limits will cause data submission to be rejected, leading to Walmart returning an error.

LitCommerce limits publishing and updating actions to a maximum of 100 listings at a time to help prevent this error from occurring.
