Get your CalSavers contribution elections through an API

What you can build on the Employer Portal

• Get contribution elections

Automate the Employer 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.

• Changed contribution elections, before each payroll

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  Get the contribution elections from the Contributions Dashboard.

  Step 2

  Keep the employees whose participation status or contribution rate changed since the last run.

  Step 3

  Post name, pay schedule, status and rate to your payroll system's webhook, and email you the same list.

• Upcoming Contributions still to send

  Build this

  Starts

  Every weekday at 9:00

  Step 1

  Get the Upcoming Contributions from the Employer Portal Dashboard.

  Step 2

  Stop when the list is empty.

  Step 3

  Email you each pay schedule and pay date, so the contributions go out within 7 days of the deduction.

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 contribution elections” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "employer.calsavers.com/get_contribution_elections",
    "input": {
      "pay_schedule": "Biweekly"
    }
  }'

{
  "status": "completed",
  "data": {
    "pay_schedule": "Biweekly",
    "employees": [
      {
        "name": "Jordan Acme",
        "pay_schedule": "Biweekly",
        "participation_status": "Enrolled",
        "contribution_rate": "5%"
      }
    ],
    "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.

The Employer Portal’s own options

CalSavers' employer pages describe no API. Contribution information syncs automatically only through a payroll provider's 360° Integration, directly with Paychex or TJH Payroll or through Payroll Integrations Inc. for a monthly fee. Otherwise your payroll provider uploads a file each payroll, or you upload the Excel template or enter amounts in the Employer Portal.

Signing in to the Employer Portal

Each person who uses the Employer Portal has their own profile: they are added under Administrators on the dashboard with a role, and get an email invitation to create the profile and activate the account. With Fous you sign in once through the Employer Portal's own sign-in with your own profile: the login is sealed with AES-256, never shown to code or agents, and an expired session is signed back in.

Worth knowing

Seven days from paycheck to CalSavers

Contributions are sent every pay period, within 7 days of deducting them from an employee's pay. A daily check of Upcoming Contributions keeps that window in view.

Elections change outside your payroll

Employees opt out with CalSavers directly, not through you, and their decisions show in the Employer Portal. Review participation status and contribution rate before each payroll: CalSavers emails you 1 to 5 days before the next pay date.

Roles decide who may do what

Payroll Processors, Supervisors and Administrators can all add employees and submit contributions. Only an Administrator edits company and bank information, so build with a profile whose role fits the method.

New hires within 30 days, 5% by default

Add new hires in the Employer Portal within 30 days of their hire date. Anyone who neither opts out nor picks a rate in the 30-day decision period is enrolled at a 5% contribution rate.
