- Missing required field: category



Resolution:

As the error outlined, the category is required from Walmart (header wmcategory and you can double check the attached Example Bulk Add Headers.csv file) and you can take a look as a reference at this guide from Walmart's knowledge base and you would be able to see further and detailed information about how to select the best categories for the different products and also double check the Categorization Guide V3.0.pdf file.
