Walmart Marketplace
This step-by-step guide explains how to connect Walmart to item systems.
Getting the API Key
- Log in to Walmart (opens in a new tab) using your account.
 - In the left panel, navigate to Apps > Connected Apps.
 

- Click Developer Portal, you will be redirected to the API Keys page.
 

- Scroll down to the My API Key section. Copy both the Client ID and Client Secret, and make a note.
 

Connecting to Walmart
After getting the API Key, sign in to item DI and follow the steps below:
- Navigate to Merchants > select the desired merchant > Connectors.
 - Select Sales Channels under the Live Channels section.
 - Click the + New Channels button. The new channels window will appear.
 - Select Walmart Marketplace from the channels list.
 - Fill out the required fields:
- Channel Name
 - Customer ID (Client ID)
 - Private Key (Client Secret)
 
 - Click Test Connection.
 - If the "Connection Successful" message appears, click Submit. The BigCommerce channel will be connected.
 

- The default switch protocol pop-up window will appear, and the system will automatically enable data syncs including order sync, shipment status sync, and inventory sync.
 - To proceed, check the box next to I agree and click Submit.
 
It’s recommended to enable data syncs when connecting channels. If you skip this step, you can still configure these options in Sales Channel Settings (opens in a new tab). When you switch to other item applications, the connected channels under this merchant will be synced as well.
