Automate Highway 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 Fail, Partial Pass or Incomplete carriers in My Network

    Build this
    Starts
    Every weekday at 6:30
    Step 1
    List the My Network carriers whose Rules Assessment is Fail, Partial Pass or Incomplete.
    Step 2
    Keep the carriers that were not on that list on the last run.
    Step 3
    Email you each one with its DOT number, Rules Assessment and failing rules.

  • Rules assessment check before a load is tendered

    Build this
    Starts
    When your TMS calls the workflow's webhook with a DOT number and load reference
    Step 1
    Check the carrier's rules assessment on Highway by DOT number.
    Step 2
    Keep the classification results, failing rules and any Identity Alerts.
    Step 3
    Post the result with the load reference back to your TMS webhook.

  • Daily Load Lock Analytics check for the compliance team

    Build this
    Starts
    Every day at 17:00
    Step 1
    Read the Load Lock Analytics tab: alerts by alert type, alerts by carrier and alerts that led to removing a carrier.
    Step 2
    Keep the carriers whose alerts changed since the last run, and stop when none did.
    Step 3
    Post those carriers with their alert counts by alert type 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 a carrier's rules assessment” would look like.

Example request
curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "highway.com/check_carrier_rules_assessment",
    "input": {
      "dot_number": "3184402"
    }
  }'
Example response
{
  "status": "completed",
  "data": {
    "carrier_name": "Northwind Freight LLC",
    "dot_number": "3184402",
    "rules_assessment": "Partial Pass",
    "classifications": [
      {
        "name": "Interstate",
        "result": "Pass",
        "failing_rules": []
      }
    ],
    "identity_alerts": [],
    "insights": [
      "Dispatch service logging in through the carrier account"
    ]
  }
}

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.

Highway’s own options

Highway's site summary says API access comes with its Connect Core plan, not with the Starter and Growth plans. Connect Core also includes TMS Integration, and Highway works inside more than 30 TMS platforms. Plans are arranged through a demo, with no prices published. Carriers use Highway for Carriers at no cost.

Signing in to Highway

Brokers sign in at highway.com/broker/login with their work email and a one-time code Highway sends by email or text, with no password. A broker account can also use single sign-on through SAML, or OIDC with Okta. With Fous you sign in once through Highway's own sign-in with your own account, and the login is sealed with AES-256. When your code comes by email, Fous handles it and signs an expired session back in.

Worth knowing

Incomplete means a missing COI
Incomplete means Highway has no valid COI from a licensed agent yet. Highway accepts COIs only from insurance agencies, never from carriers or brokers. A carrier requests one under Equipment > Insurance > Update Insurance.
Read the failing rules, not only the result
Each classification is a bundle of rules, and Partial Pass means a carrier is approved for some classifications only. In the new interface the rules that caused a failure appear first.
The interface changed on October 8, 2026
The updated interface became the default on October 8, 2026, with a toggle back to the classic one. My Network and Connections are now one page, and Loads Index and TFX Loads one loads view.
Single sign-on ends the emailed codes
Once SSO is configured for your email domains, every login goes through your identity provider and Highway stops sending codes by email or text. Highway does not support SCIM provisioning.

Frequently asked questions

Yes, on the Connect Core plan, which Highway's site summary says includes API access; the Starter and Growth plans do not. Plans are arranged through a demo, with no prices published. Connect Core also includes TMS Integration, and Highway works inside more than 30 TMS platforms.

Partial Pass means the carrier is approved for some classifications only, such as interstate and hazmat but not high value. Incomplete means Highway has no valid COI from a licensed agent yet. For a Fail, read the failing rules, which the updated interface lists first.

Yes. Highway's unified search covers carriers, vehicles, VINs and contacts, and a carrier's Equipment tab can be searched by VIN. With Fous you can build a method that takes a VIN and returns the carrier and vehicle details as JSON.

Yes, with a workflow you build. With Fous, a workflow can run on a schedule, read My Network, keep the carriers that fail or are Incomplete, compare with the last run and email you the new ones.

No. Fous is an independent product. You use it with your own Highway account, and a method reads and does only what that account can.
