Automate ShipCSX 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.

• Inbound railcars in jeopardy, every morning

  Build this

  Starts

  Every weekday at 6:00

  Step 1

  List the inbound cars at each of your locations with Trace by Location.

  Step 2

  Trace those cars by equipment ID to read their shipment status, ETA and any jeopardy.

  Step 3

  Keep the cars with a jeopardy or an ETA that changed since the last run.

  Step 4

  Email you the list by location, with equipment ID, ETA and jeopardy reason.

• Cars accruing demurrage, posted to your yard team

  Build this

  Starts

  Every weekday at 7:30

  Step 1

  Get the current month's demurrage charges for each location.

  Step 2

  Keep the cars that were not charged on the last run.

  Step 3

  Post each car, its placement status and charge to your Slack or yard system webhook.

• Freight invoice aging, handed to accounting

  Build this

  Get the open account invoices and aging for each account.

  Step 2

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 “Trace railcars by equipment ID” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "shipcsx.com/trace_equipment",
    "input": {
      "equipment_ids": [
        "ACMX 104522",
        "ACMX 104587"
      ]
    }
  }'

{
  "status": "completed",
  "data": {
    "cars": [
      {
        "equipment_id": "ACMX 104522",
        "shipment_status": "In transit",
        "trip_plan": "Departed origin yard 2026-11-10, arriving serving yard 2026-11-13",
        "eta": "2026-11-13T14:00:00-05:00",
        "waybill": {
          "number": "604118",
          "origin": "Acme Plastics, Louisville, KY",
          "destination": "Northwind Packaging, Charlotte, NC"
        },
        "jeopardy": null
      }
    ],
    "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.

ShipCSX’s own options

CSX says it requires customers to use electronic tools for shipping transactions, and its tools for them are ShipCSX, EDI and B2B file exchange. Its EDI transaction sets include freight bills (410), waybills (417), plant switch lists (423) and freight payments (820). B2B takes your own file format and CSX transforms it.

Signing in to ShipCSX

ShipCSX signs you in with a ShipCSX user ID and password, which CSX issues to its customers when they register. With Fous you sign in once through ShipCSX's own sign-in with your own user ID. The login is sealed with AES-256, never returned by the API or written to logs, and code and AI agents never see it.

Worth knowing

Account Invoices needs a setup call

Account Invoices under the Pay tab requires a quick setup by phone with CSX (1-877-744-7279, option 2) before a ShipCSX user can see invoices there.

Demurrage history goes back 4 months

Demurrage Charges shows the current month in real time and the previous 4 months as history, by location, account or rail car. Older months are not in the tool.

Intermodal is traced elsewhere

Pipeline Trace covers carload equipment. Intermodal containers and trailers are traced in the separate Intermodal Tracking Suite, so build a separate method for them.

Shipping instructions can be fixed in one place

ShipCSX Shipping Instructions can correct or cancel any CSX shipping instruction, however it was first sent, and shows the status of all instructions for your location.
