Automate Ad Center with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• Yesterday's keyword rows in your warehouse, every day

  Build this

  Starts

  Every day at 11:30 Pacific Time

  Step 1

  Request the Keyword Performance report for yesterday.

  Step 2

  Stop when it has no rows.

  Step 3

  Post the rows to your data warehouse's webhook, so your history outlasts Ad Center's 62 days.

• Keywords that spend without selling, once a week

  Build this

  Starts

  Every Monday at 12:00 Pacific Time

  Step 1

  Request the Keyword Performance report for the last 14 days.

  Step 2

  Keep the bidded keywords with ad spend over the amount you set and no orders.

  Step 3

  Email you the list, highest ad spend first.

• Bid changes from your own rules, applied

  Build this

  Starts

  When your system calls the workflow's webhook with a keyword and a bid

  Step 1

  Set the new bid on that keyword in its ad group.

  Step 2

  Post the previous bid, the new bid and the keyword's state back to your system.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get a Keyword Performance report” would look like.

curl https://api.fous.com/v1/runs \

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

Ad Center’s own options

Walmart Connect has Sponsored Search and Display APIs for its API partners: technology providers and technology-enabled agencies that complete partner onboarding, including a sandbox demo and a production demo. An advertiser's Admin grants a partner access, with at most 10 API partners per Search account. Advertisers themselves use Ad Center or a partner's tool.

Signing in to Ad Center

You sign in to Ad Center with your Seller Center or Supplier Center credentials, and the account's Admin grants each user access. Seller Center accounts use 2-step verification: a one-time code from an authenticator app, email or text message at each login. With Fous you sign in once through Walmart's own sign-in with your own account. Emailed codes are handled, and Fous signs back in when the session expires.

Worth knowing

Sponsored Search reports run on Pacific Time

Walmart states that Sponsored Search uses Pacific Time in both the API and the Ad Center UI, while Display uses Eastern Time. Match your own day boundaries to that before you compare numbers.

Yesterday's data arrives mid-morning Pacific

For its API, Walmart says the previous day's data is made available daily by 10 to 11am PST, and that earlier requests return data up to two days back. Schedule a daily pull after that window.

Report history goes back 62 days

Since October 8, 2025, the API's snapshot reports can be retrieved for 62 days, down from 90, a window Walmart says aligns with Ad Center. Store each pull yourself if you need a longer history.

Suppliers and sellers get different reports

Brand Performance and Category Performance are for suppliers (1P) only. Placement Performance and Item Keyword Performance are listed for auto bidded and keyword bidded campaigns, not for Sponsored Brands or Sponsored Videos.
