Connect Walmart Marketplace to AskBiz

Q: My Client Secret disappeared before I could copy it. What do I do?

You cannot retrieve a Client Secret after it is generated. Return to Walmart Seller Center → Developer Tools, revoke the existing key, and generate a new one. Copy the new Client Secret immediately and update the connection in AskBiz Sources.

Q: AskBiz says my credentials are invalid but I copied them correctly.

The most common cause is using the old Walmart API format — Consumer ID and Private Key — which uses RSA signatures and is not compatible. AskBiz requires the newer Client ID and Client Secret format from Walmart Developer Tools. If your Seller Center account predates 2021, you may need to generate new credentials.

Q: Does AskBiz support Walmart Canada or Walmart Mexico?

Not currently. AskBiz connects to the US Walmart Marketplace only. Canada and Mexico marketplace support is planned for a future release.

Q: Where does the marketplace fee figure come from?

AskBiz estimates the Walmart referral fee at 8% of the item price, which is the approximate average across most categories. Actual fees vary by category (typically 6–15%). You can see the estimated fee per order in the CFO Mode cost breakdown.

Step-by-step guide to connecting your Walmart Marketplace seller account and syncing orders and revenue data.

Before you start#

You will need:

An active Walmart Marketplace seller account (US marketplace)
Access to Walmart Seller Center → Developer Tools
Your account must be approved and in good standing

Walmart Marketplace connection requires the Growth or Business plan.

Step 1 — Generate API credentials in Seller Center#

Log in to Walmart Seller Center and go to Settings → Developer Tools (or search for 'API' in the top navigation).

Click Add new key for a Solution Provider or Seller App. Give it a name (e.g. AskBiz), set permissions to Read Only, and confirm.

You will receive a Client ID and Client Secret. Copy both — the Client Secret is shown only once.

Step 2 — Connect in AskBiz#

In AskBiz, go to Sources and click Connect next to Walmart.

Enter:

Client ID — the UUID from Seller Center
Client Secret — the secret shown after key generation

Click Connect. AskBiz immediately validates your credentials against the Walmart API — if they are correct the connection is confirmed, if not you will see a specific error message explaining the problem.

Step 3 — Initial data import#

The first import pulls your orders from the last 90 days. This typically takes 2 to 10 minutes. Once complete, your Walmart orders appear in Intelligence, CFO Mode, and the Ask tab.

Walmart orders include line-item detail, product names, SKUs, shipping costs, and your estimated marketplace referral fee.

Ongoing sync#

After the initial import, AskBiz syncs new Walmart orders every 6 hours. To trigger an immediate sync, go to Sources, find Walmart, and click Sync Now.

Note: Walmart access tokens expire after 15 minutes. AskBiz handles token refresh automatically — you do not need to reconnect.
