In order for the tag to be activated on your Walmart listings, you'll need to configure 4 shipping overrides per listing. This can be done within ChannelAdvisor.
To do so, you'll have to create some custom attributes. Navigate to Inventory > Grouping > Attributes.
Click on "Create New Attribute" in the top right.
Then, create 4 custom attributes exactly as shown below:
Then, navigate to your Walmart templates:
Marketplaces > Walmart Marketplace > Product Mapping > Template
Select "Item level Shipping Overrides" from the left-hand column.
For Continental U.S, map the Walmart shipping options to the custom attributes created before (For Expedited, please set an override price to $0):
Then, update the template.
Do not complete the below step until your inventory is received in Deliverr.
For the items you'd like to activate on the 2-Day tag, set the custom attributes to the following (this can be done in bulk or in the UI by going to the custom attributes section of a SKU):
1. Walmart - 1 Day Shipping? No.
2. Walmart - 2 Day Shipping? Yes
3. Walmart - Standard Shipping? No
4. Walmart - Value Shipping? No
Then update the product. It may take over a day for the shipping overrides to take effect.
