Automate MiUI 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.

• Check that last quarter's wage report is filed

  Build this

  Starts

  Monthly on the 15th at 9:00, America/Detroit

  Step 1

  Check quarterly wage report submissions for the quarter that last ended.

  Step 2

  Stop the run when that quarter has a submitted report.

  Step 3

  Email you the quarter and the last quarter that was submitted, with its date.

• Changes to your Associated TPA(s)

  Build this

  Starts

  Every Monday at 8:00, America/Detroit

  Step 1

  List the associated TPAs and their roles from the Employer Homepage.

  Step 2

  Keep the TPAs that were added, removed or given other roles since the last run.

  Step 3

  Post each change, with TPA ID, roles and dates, to your compliance or payroll system's webhook.

• Wage report status to your payroll records

  Build this

  Starts

  When your payroll system calls the workflow's webhook with a quarter

  Step 1

  Check quarterly wage report submissions for that quarter.

  Step 2

  Post quarter, submission method, submitted date, status, employees and total wages to your payroll system's 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 “Check quarterly wage report submissions” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "miui.michigan.gov/get_wage_report_submissions",
    "input": {
      "quarter": "2026 Q3"
    }
  }'

{
  "status": "completed",
  "data": {
    "employer": "Northwind Fabrication LLC",
    "submissions": [
      {
        "quarter": "2026 Q3",
        "submission_method": "File Upload",
        "submitted_date": "2026-10-14",
        "status": "Submitted",
        "employees_reported": 42,
        "total_wages": 618240.55,
        "currency": "USD"
      }
    ],
    "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.

MiUI’s own options

The UIA's MiUI material describes no API. Quarterly Wage Reports are typed in, copied from the previous quarter or uploaded as a file in Delimited, EFW2, ICESA or XML format, and a testing tool checks a file before you submit it. A third-party administrator with the right role can file for you.

Signing in to MiUI

MiUI signs employers in through MiLogin for Business with a username and password. An existing employer links its account once through Employer Account Initiation. With Fous you sign in through MiUI's own sign-in with your own MiLogin for Business account: the login is sealed with AES-256, never returned by the API or written to logs. When a session expires, Fous signs back in.

Worth knowing

Activate the employer account first

Employer Account Initiation asks for your 9-digit FEIN, the first seven digits of your Employer Account Number and an 8-digit activation code that MiWAM showed to users with Master access.

A report is due even with no wages

You must file a Quarterly Wage Report even with no employees or wages. MiUI has a No Employment and No Wage Report option for that quarter.

Old MiWAM files are not accepted

The MiWAM delimited format used for 1028 files is no longer supported. Use Delimited, EFW2, ICESA or XML, and test the file with Quarterly Wage Report Testing first.

A TPA needs the right role

A TPA files with the Submit Employment and Wage Detail role. You add it under Associated TPA(s) on the Employer Homepage, then assign its dates and roles on the Third-Party Administrator (TPA) Information page.
