Walmart Marketplace Sync Errors

AskBiz validates your Walmart credentials immediately when you connect. If you see an invalid credentials error:

1. Log in to Walmart Seller Center → Settings → Developer Tools

2. Confirm you are copying the Client ID (a UUID) and Client Secret exactly — check for leading or trailing spaces

3. If you generated the key more than a few minutes ago and the secret is no longer visible, revoke the key and generate a new one — the secret cannot be retrieved after initial display

4. Make sure the key was created under your own Seller Center account, not a Solution Provider's account

Note: AskBiz uses the newer Client ID + Client Secret format. If your Walmart account previously used Consumer ID and Private Key (RSA-based), generate new credentials in Developer Tools.

If connection succeeds but orders are missing after the initial sync:

• The initial sync covers the last 90 days — check that you had orders in that window
• Orders must be in Acknowledged, Shipped, or Delivered status; draft or cancelled orders are not imported
• Allow 2–10 minutes for the first sync to complete on large accounts
• Go to Sources and click Sync Now to force an immediate refresh

Walmart access tokens expire after 15 minutes. AskBiz refreshes tokens automatically before each sync, but if your Client Secret has been rotated or revoked in Seller Center the refresh will fail.

If sync stops:

1. Go to Sources and click Reconnect next to Walmart

2. Enter your current Client ID and Client Secret

3. AskBiz will re-validate and resume syncing

To avoid interruptions, do not revoke Walmart API keys without reconnecting AskBiz immediately afterward.

If validation passes but syncing fails with a permission error, your API key may lack Orders read permission.

In Walmart Seller Center → Developer Tools, check the permissions assigned to your key. It needs at minimum Orders → Read. If permissions cannot be edited after creation, generate a new key with the correct permissions.
