Automate PierPASS 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.

• Morning list of containers not yet released

  Build this

  Starts

  When your system calls the workflow's webhook with the day's container numbers

  Step 1

  Check the TMF status of each container number your system sent.

  Step 2

  Keep the containers with no TMF release sent to the terminal.

  Step 3

  Email you the list with each container's status and TMF amount.

• Export bookings not yet claimed

  Build this

  Starts

  When your system calls the workflow's webhook with new export booking numbers

  Step 1

  List the export booking numbers claimed in your PierPASS account.

  Step 2

  Keep the booking numbers your system sent that are not in that list.

  Step 3

  Post them to your system's webhook so someone claims them before the containers arrive.

• TMF releases, posted to your drayage system

  Build this

  Starts

  Every 30 minutes on weekdays

  Step 1

  Check the TMF status of the containers you are tracking.

  Step 2

  Keep the containers whose TMF release was sent since the last run.

  Step 3

  Post each container number, paid date and TMF amount to your 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 TMF status of containers” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "pierpass-tmf.org/check_tmf_status",
    "input": {
      "container_numbers": [
        "ACMU4821937",
        "NWDU7730415",
        "GLBU2219864"
      ]
    }
  }'

{
  "status": "completed",
  "data": {
    "containers": [
      {
        "container_number": "ACMU4821937",
        "size": "40",
        "status": "Active",
        "tmf_amount": 81.26,
        "pay_available": false,
        "paid_date": "2026-11-12",
        "release_sent": true
      }
    ]
  }
}

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.

PierPASS’s own options

PierPASS collects the Traffic Mitigation Fee through the web portal at pierpass-tmf.org: you register a company account, claim export booking numbers and pay there. The PierPASS and WCMTOA sites describe no API or data feed. What the account adds is email notifications on account events and payment by prepaid account or credit agreement.

Signing in to PierPASS

PierPASS signs you in with a Login ID and a password, and the same Login ID and password also sign you in to PortCheck. A company can set up several logons on its account. With Fous you sign in once through PierPASS's own sign-in with your own account; the login is sealed with AES-256, code and AI agents never see it, and when a session expires Fous signs back in.

Worth knowing

Claim export bookings before the gate

The booking number for an export container must be claimed in your PierPASS account before the container arrives. A container whose booking number is not claimed is not permitted to enter the terminal.

Export fees are due before the next Tuesday

For exports paid by card, debit card or eCheck, the TMF is due before the Tuesday after the container enters the terminal. Exports cannot be delivered while payment on past containers is not current.

Import fees are paid before the container leaves

Unless other arrangements are made, the TMF on an import container must be paid before it leaves the terminal. Once paid, PierPASS sends a TMF release to the terminal.

Refunds have a 30-day window

If you paid the TMF on a container that is exempt from it, you can ask PierPASS for a refund within 30 days of the payment date.
