To connect Walmart to 3Dsellers, open Settings → Integrations → Walmart Accounts, click Add Walmart Account, sign in to Walmart with your seller account and authorize 3Dsellers. You no longer create a Client ID and Client Secret in the Walmart Developer Portal. 3Dsellers connects Walmart US Marketplace seller accounts.
Did you connect Walmart before mid-November 2024 by pasting a Client ID and Client Secret? Walmart switches those keys off on April 30, 2027, so that connection must be reconnected before then. Message us in the chat first, and we will move it for you. See Reconnecting an older Walmart connection below.
How do I connect my Walmart account to 3Dsellers?
Before you start: you need an approved Walmart Marketplace seller account in the US and the login you use for Walmart Seller Center. No Walmart seller account yet? Click Open A New Walmart Account on the Walmart Accounts page, or see How to Sell on Walmart Marketplace from eBay with 3Dsellers.
In 3Dsellers, open Settings → Integrations and click Walmart Accounts. You can also go straight to app.3dsellers.com/integrations/walmart.
Click Add Walmart Account.
In the window that opens, click Add. The United States is the only Walmart marketplace you can choose.
Walmart's sign-in page opens in a new window. Sign in with your Walmart Seller Center login.
Walmart shows the access 3Dsellers is asking for. Approve it.
Walmart sends you back to 3Dsellers, and your store appears in the Walmart Accounts list.
Your Walmart orders and listings then start syncing into 3Dsellers. A large store can take a while. To publish your catalog products to Walmart, see Publish Catalog Products to eBay and Other Channels.
Can I connect Walmart Canada or Walmart Mexico?
No. 3Dsellers connects Walmart US Marketplace seller accounts only. Walmart Canada and Walmart Mexico seller accounts can't be added.
Can I connect 3Dsellers from the Walmart App Store?
Yes. Open the 3Dsellers app in the Walmart App Store and click Connect. Walmart sends you to 3Dsellers to finish the same sign-in and authorization. If you already have a 3Dsellers account, log in to it in the same browser first, so Walmart is added to your existing account and not to a new one.
Reconnecting an older Walmart connection
Until November 2024, connecting Walmart meant adding 3Dsellers as a solution provider in the Walmart Developer Portal and pasting the Client ID and Client Secret that Walmart generated into 3Dsellers. Walmart is retiring these keys (Walmart calls them delegated access keys):
Walmart stopped creating new keys on July 30, 2026.
Existing keys stop working on April 30, 2027. A Walmart account that is still connected with a Client ID and Client Secret after that date stops syncing.
A Walmart account connected this way must be reconnected before April 30, 2027. Message us in the chat before you reconnect, and our team will move your Walmart connection over for you. Please don't add the same Walmart store again with Add Walmart Account yourself.
Not sure how your account was connected? Accounts connected from mid-November 2024 onward already use Walmart sign-in and need no action. If you remember pasting a Client ID and Client Secret, or you're not sure, message us in the chat and we will check for you.
Troubleshooting
A guide told me to create a Client ID and Client Secret in the Walmart Developer Portal
That is the old method. Walmart no longer creates new Client IDs and Client Secrets for solution providers such as 3Dsellers, and you don't need one. Click Add Walmart Account and sign in to Walmart instead.
My Walmart account shows a yellow Renew Token button
3Dsellers shows Renew Token (tooltip: Renew token now to avoid service interruption) when Walmart no longer accepts the account's connection. New orders for that account stop coming in until you renew it. Click Renew Token, sign in to Walmart with the same seller account and authorize 3Dsellers again. Walmart accounts have no sync icon, so Renew Token is how you refresh the connection. Only the admin user of your 3Dsellers account can renew tokens. If this account was connected with a Client ID and Client Secret, message us in the chat instead.
Nothing happens after I continue to Walmart
Walmart's sign-in opens in a new browser window. If your browser blocks pop-ups, allow pop-ups for app.3dsellers.com and try again.
