Automate RMIS 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.

• Not certified at any broker, every morning

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  For each broker portal you list, get the certification status.

  Step 2

  Keep the portals where you are not certified.

  Step 3

  Email you the broker names with every reason from the red box.

• Certification lost since yesterday, posted to dispatch

  Build this

  Starts

  Every day at 6:00

  Step 1

  For each broker portal, get the certification status.

  Keep the brokers where you were certified on the last run and are not now.

  Step 3

  Post each one, with its reasons, to your dispatch system's webhook.

• Weekly compliance summary by reason

  Build this

  Every Monday at 8:00

  Step 1

  For each broker portal, get the certification status and its reasons.

  Step 2

  Group the reasons into insurance, W9 and DOT authority.

  Step 3

  Email you one summary with the brokers affected under each group.

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 certification status” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "rmissecure.com/get_certification_status",
    "input": {
      "portal": "acmecarriers.rmissecure.com"
    }
  }'

{
  "status": "completed",
  "data": {
    "portal": "acmecarriers.rmissecure.com",
    "broker": "Acme Logistics",
    "certified": false,
    "status": "Not certified",
    "reasons": [
      "Cargo has expired: 11/01/2026",
      "Additional Insured not found for Auto",
      "W9TIN: Check Pending"
    ]
  }
}

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.

RMIS’s own options

Truckstop documents RMIS APIs for the brokers who monitor carriers: newly onboarded and updated carriers, carrier details, documents, invitations and registration steps. Nothing in that documentation is for carriers. As a carrier you use each broker's RMIS carrier portal, and your insurance agent sends certificates to RMIS.

Signing in to RMIS

Each broker's RMIS carrier portal has its own address on rmissecure.com, and you sign in with the username and password from that broker's registration confirmation email. RMIS then asks for multi-factor authentication: biometrics or a security key, an SMS code, or an authenticator app. With Fous you sign in through each portal's own sign-in with your own account, and the login is sealed with AES-256.

Worth knowing

One portal per broker

Each broker has its own RMIS carrier portal address and its own login, sent in that broker's registration confirmation email. Build your methods to take the portal address as an input, and a workflow can loop over your brokers.

Certificates come from your agent

RMIS accepts an insurance certificate only when your insurance agent sends it, not when anyone else does. A reason such as an expired Cargo coverage is fixed by your agent, not in the portal.

Updates take time to show

RMIS takes 24 to 48 hours to update an insurance certificate. A new electronic W9 shows W9TIN: Check Pending while it is checked with the IRS, which can take up to 6 hours.

FMCSA fields cannot be edited

Your MC, DOT, company name and main number come from the FMCSA and cannot be changed in the portal. A DOT authority reason, such as NOT AUTHORIZED, is resolved with the FMCSA.
