Automate Access Online 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.

• Pending transactions before the cycle closes

  Build this

  Starts

  Every weekday at 8:00

  Step 1

  For each card account you name, get the card transactions in the current billing cycle.

  Step 2

  Keep the transactions whose Approval Status is still Pending.

  Step 3

  Email you the list, one section per card account.

• Transactions without a receipt, every Monday

  Build this

  Starts

  Every Monday at 9:00

  Step 1

  For each card account, get the card transactions posted in the last 7 days.

  Step 2

  Keep the transactions with no attachment.

  Step 3

  Post each one, with card account, merchant, amount and posting date, to your Slack webhook.

• Approved transactions, posted to your ERP

  Build this

  Starts

  Every day at 18:00

  Step 1

  For each card account, get the card transactions with Approval Status Approved.

  Step 2

  Keep the transactions that were not on the last run's list.

  Step 3

  Post each one, with its accounting code and description, to your ERP webhook.

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 card transactions” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "access.usbank.com/get_card_transactions",
    "input": {
      "card_last4": "4821",
      "from": "2026-10-21",
      "to": "2026-11-12",
      "approval_status": "Pending"
    }
  }'

    "account_name": "Acme Facilities PCard",
    "card_last4": "4821",

        "description": null
      }
    ],
    "count": 1
  }
}

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.

Access Online’s own options

U.S. Bank publishes APIs for its card programs on its Developer Portal: one retrieves Access Online transactions, orders and attachments, another creates and maintains card accounts and spending controls. Your organization must be verified there and request production access for each API. Without that, you work in Access Online itself.

Read on November 12, 2026: Access Online Transactions API, Corporate Credit Cards API, Getting started with U.S. Bank APIs.

Signing in to Access Online

Access Online asks for your organization short name, user ID and password, and you set up authentication questions when you register. Department of Defense card users sign in through PIEE single sign-on instead. With Fous you sign in through Access Online's own sign-in with your own account, and the login is sealed with AES-256, never returned by the API or written to logs.

Worth knowing

Saved is not approved

A reallocation stays Pending after Save Allocations until you click Approve. Changes made on the Allocations tab are lost if you leave without saving them.

Approval locks the transaction

An approved transaction moves to the approver's queue and is locked. To change it, you click Pull Back, make the change and approve it again.

Attachments: 5MB per transaction

You can attach PNG, JPG or PDF files to a transaction, and they are converted to PDF. All files on one transaction together may not exceed 5MB.

Statements follow your billing cycle

Statements are under Account Information, Cardholder Account Statement. In one state's program guide, the cycle closes on the 20th and the statement is ready the next business day.
