Automate Unemployment Services 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.

• New fact-finding requests, every employer

  Build this

  Starts

  Every weekday at 8:00

  Step 1

  For each EAN you list, get the Action center requests.

  Step 2

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

  Step 3

  Email you the list grouped by employer, with each request's type and response due date.

• New benefit charges statements, ready to check

  Build this

  Starts

  Every Monday at 9:00

  Step 1

  For each EAN, get the benefit charges statements from the last 30 days.

  Step 2

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

  Step 3

  Post the EAN, statement date, each claimant's charge amount and statement total to your webhook.

• Wage detail reports still to file before the deadline

  Build this

  Starts

  Every month on the 20th at 9:00

  Step 1

  For each EAN, check wage report and payment status for this year and last year.

  Step 2

  Keep the quarters that still show File Now, and stop the run when there are none.

  Step 3

  Email you the employers and quarters still to file.

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 Action center requests” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "unemployment.mass.gov/get_action_center_requests",
    "input": {
      "ean": "00099999"
    }
  }'

{
  "status": "completed",
  "data": {
    "employer": "Northwind Logistics LLC",
    "ean": "00099999",
    "requests": [
      {
        "type": "Fact-finding request",
        "request_date": "2026-11-09",
        "response_due": "2026-11-19"
      }
    ],
    "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.

Unemployment Services’s own options

The DUA's employer guides describe no API. Wage detail reports can be uploaded in the account as Massachusetts Standard CSV, EFW2 or ICESA files, and DUA's TPA instruction set describes sending the same files to a predefined FTP location. Fact-finding requests, letters and payments are handled in the account.

Signing in to Unemployment Services

Unemployment Services signs you in with a MyMassGov business account: your email address as the username, a password and multifactor authentication by authenticator app, text message or voice call. Every user needs their own account. With Fous you sign in through the site'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

Fact-finding requests have 10 days

Employers must respond to fact-finding requests within 10 days of the request date. A late response may affect your rights in the claim, so a daily check of the Action center matters.

Charge protests have 30 days

A protest must be submitted within 30 days of the statement date when a claimant's charges first appeared. View letters shows 12 months in the Received tab; older letters need a date range in the Search tab.

One bad record holds back the report

In an uploaded file, an error in one record stops every record of that wage report, meaning the same employer, year and quarter. Other employers' reports in the same file are still processed.

Third-party administrators work per employer

A TPA picks the employer from its list of businesses. Access comes from the employer approving the request in its Action center, an employer grant or a power of attorney form.
