Turn your Workday reports and Inbox into an API

What you can build on Workday

• Run a report and return its rows

  Report name, report prompts (optional)

  One record per row, with the report's own column names, and the row count

  Task, business process, worker it concerns, date received

• Approve one Inbox item

  Build this

  Opens one item on the Actions tab of the Inbox, adds an optional comment and approves it.

  Takes

  Task name, worker, comment (optional)

  Returns

  Task, worker, result, time approved

Automate Workday 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.

• Outstanding actions for your direct reports, each morning

  Build this

  Starts

  Every weekday at 7:30

  Step 1

  Run the report Outstanding Actions for My Direct Reports.

  Step 2

  Keep the rows that were already there on the last run, so you see what has waited since then.

  Step 3

  Email you the list, grouped by worker.

• Inbox summary, grouped by business process

  Build this

  Starts

  Every Monday at 8:00

  Step 1

  List the items on the Actions tab of your Workday Inbox.

  Step 2

  Stop when the Inbox is empty.

  Step 3

  Group the items by business process and post the summary to your Slack webhook.

• A weekly report, posted to your warehouse

  Build this

  Starts

  Every Monday at 6:00

  Step 1

  Run the report you name, with the prompts you give.

  Step 2

  Keep the rows that changed since the last run.

  Step 3

  Post them as JSON to your data warehouse 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 “Run a report and return its rows” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "myworkday.com/run_report",
    "input": {
      "report": "Outstanding Actions for My Direct Reports"
    }
  }'

{
  "status": "completed",
  "data": {
    "report": "Outstanding Actions for My Direct Reports",
    "rows": [
      {
        "worker": "Jordan Smith",
        "business_process": "Request Time Off",
        "step": "Approval by Manager",
        "awaiting": "You",
        "initiated_on": "2026-11-10"
      },
      {
        "worker": "Sam Taylor",
        "business_process": "Submit Expense Report",
        "step": "Review by Cost Center Manager",
        "awaiting": "Cost Center Manager",
        "initiated_on": "2026-11-06"
      }
    ],
    "count": 2
  }
}

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.

Workday’s own options

Workday's APIs work inside your company's own tenant: SOAP web services, REST and Graph APIs authorized with OAuth 2.0, and reports called as a service. API clients are created in the tenant, and only a Company Administrator can allow one on a production tenant, so API access comes through your Workday administrators. Without it you have Workday itself and its report exports.

Signing in to Workday

Workday has no shared sign-in page: each company gives its people a link to its own sign-in page, and its HR or IT department handles access. With Fous you sign in once through your company's Workday sign-in with your own account. The login is sealed with AES-256, never returned by the API or written to logs, and a method reads and does only what your account can.

Worth knowing

Every company's Workday is its own

Each company has its own sign-in page and its own settings. Features such as Print Multiple Payslips and report exports depend on them, so a method is built against your company's Workday.

Security permissions decide the exports

Export to Excel, Export to Worksheets and Print on a report are shown only when your company's security permissions allow them. A method sees the same reports your account does.

Print Multiple Payslips runs in the background

Printing several payslips at once is a setting your company may not enable. When it is on, the PDF is generated in the background and appears in your notifications when processing completes.

The Inbox Archive keeps 30 days

The Inbox has two tabs: Actions for tasks waiting on you and Archive for tasks you completed in the last 30 days. Keep your own record if you need a longer history.
