Creating Variants for Walmart

Managing item variants on Walmart requires careful category selection and specific attribute setup:

• Select the correct category: Start by choosing the appropriate category for your items. Some categories may not support variants, so selecting the right one is crucial for variant configuration.

• Configure Variant attributes: After category selection, set up your variant attributes:

  • Variant Group ID: Use a common identifier for all variants in a group, such as parent_id or item_group_id.

  • Variant attribute name: Specify the attribute that differentiates the variants (e.g., color, size).

  • Variant code field: Assign the field associated with the variant code.

• Enter Variant codes: Enter multiple variant codes by separating each with a comma (,). Although this might trigger an error message in Channable, you can disregard it as Walmart will still process the entries correctly. Do not end any entered value with a comma, as Walmart will reject the attribute.
