Additional requirements for Walmart
The following information is specific to Walmart.
Shipping template tab
-
Shipping template ID:
To link your products to specific shipping templates, you need to first create the shipping templates for your products on Walmart as explained in this Walmart Seller Help article. When you are done creating a template, Walmart will generate a Shipping Template ID. You will need to maintain or modify your Shipping templates on Walmart's platform.
Each template you create on Walmart generates a unique Shipping Template ID. Enter this ID in Channable’s “Build > Shipping templates” section.
To assign different Shipping Templates to various products, utilize dynamic fields and rules in Channable, ensuring each product is matched with the correct Shipping Template ID.
-
Fulfillment center template ID:
This ID represents the US-based location from which your orders are shipped. Similar to Shipping Templates, you must set up and maintain your Fulfillment Center template on Walmart according to this Walmart Seller Help article to generate the Fulfillment Center ID. Enter this ID in Channable to ensure your products are associated with the correct fulfillment location.

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 the Variant attributes by filling in the following:
-
Variant Group ID: Use a common identifier for all variants in a group, such as
parent_id
oritem_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.
Step 4: Send your products to Walmart
Your product listings should now be ready to be sent. If you have not activated your project, go to your project settings on the left-hand side of the screen and click "Activate project".
After, go back to the APIs overview and go to [Your Walmart API] > Settings, where you can activate the API by clicking "Activate API".
Once you have activated the API, navigate back to the API overview and click on the blue "Run now" button to send your product listings to Walmart.
After the initial upload, you'll see items marked as successfully pushed in Channable, indicating they've been created on Walmart without price and inventory details. In the next export, Channable will update these items with their respective prices and inventories. Use the Walmart Dashboard to monitor the publishing status of each item.
Step 5: Check your product listings for errors
After you have sent your product listings to Walmart, go to the Results tab of your Walmart API.
For errors, click filter on 'error'. Now you can see which product listings have errors and which are not listed. Click on a specific error to see more information on what is causing the error. If you have solved some errors by changing the settings or product information, re-run the Walmart API to see the new results.
