Automate the Supplier Portal 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.

• Cases that moved overnight

  Build this

  Starts

  Every weekday at 8:00

  Step 1

  Get your cases from Cases.

  Step 2

  Keep the cases whose status changed since the last run.

  Step 3

  Email you the list with case number, case type, old and new status.

• New supplier Updates for your team

  Build this

  Starts

  Every Monday at 9:00

  Step 1

  Read the supplier Updates on the toolbar.

  Step 2

  Keep the updates that were not there on the last run.

  Step 3

  Summarize each one in two sentences and post them to your team's webhook.

• Portal admin check for every account

  Build this

  Starts

  On the 1st of every month at 9:00

  Step 1

  List the Portal admins per SAP Business Partner number from your profile.

  Step 2

  Keep the accounts whose admin changed since the last run.

  Step 3

  Email you each one with the account and its admin.

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 your cases” would look like.

  -H "Content-Type: application/json" \

        "last_updated": "2026-11-06"
      }
    ]
  }
}

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.

The Supplier Portal’s own options

The Supplier Portal's public pages document no supplier API. Asda exchanges orders and invoices with suppliers over EDI, and the portal itself, built by ServiceNow to replace the gateway once reached through Retail Link, is where you reach Asda's applications, documents, knowledge articles and support cases by hand.

Signing in to the Supplier Portal

The Supplier Portal signs you in on a Microsoft sign-in page: your email address, then a password or a code sent to that email, or your organisation's own sign-in for a work account. Multi-factor authentication is required, on a mobile device with Microsoft Authenticator, another authenticator app or an SMS code. With Fous you sign in on that page with your own account, and the login is sealed with AES-256.

Worth knowing

Users come from your Supplier Admin

Only your Supplier Admin can request new Supplier Portal users or change their access. An extra admin needs Asda's approval, because each admin user has a licensing cost to Asda.

MFA is linked to your mobile device

If you change or lose the phone, ask for an MFA reset in an Access & Application Issues case. The Authentication or Password Issues form covers users who have not accessed the portal in the last 30 days.

One user can reach several accounts

Admins can request access to each SAP Business Partner number your business has. The 10-digit number is on remittances and in every user's profile area, so it is a good key for matching accounts in your own systems.

Legacy Walmart queries have their own format

A Disputed Debits - Goods For Resale case needs the Walmart debit note number with -P or -Q at the start, the Walmart Item number rather than the Article number, and the evaluation or PO date in the comments.
