Automate the Traverse 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.

• New compliance charges, grouped by program

  Build this

  Starts

  Every Monday at 8:00

  Step 1

  Read every charge listed in Find Charges.

  Step 2

  Keep the charges that were not there on the last run.

  Step 3

  Email you the list grouped by OTIF, Small Parcel and ASN, with PO number and amount.

• Charges close to the 45-day dispute window

  Build this

  Starts

  Every weekday at 7:30

  Step 1

  Read every charge listed in Find Charges.

  Step 2

  Read Find Disputes and drop the charges already disputed.

  Step 3

  Keep the charges deducted 35 to 45 days ago and email you the list.

• Dispute outcomes posted to your deductions system

  Build this

  Starts

  Every day at 17:00

  Step 1

  Read the records in Find Resolved Disputes and Find Reversals.

  Step 2

  Keep the ones that changed since the last run, and stop when there are none.

  Step 3

  Post each one to your ERP or deductions system's 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 “Find compliance charges” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "cvs.traversesystems.com/find_compliance_charges",
    "input": {
      "charge_numbers": []
    }
  }'

{
  "status": "completed",
  "data": {
    "charges": [
      {
        "charge_number": "50817342-OT",
        "program": "OTIF",
        "charge_type": "Compliance",
        "description": "Shipment arrived after the must-arrive-by date",
        "po_number": "7104558",
        "amount": 412.6,
        "deduction_date": "2026-11-02"
      }
    ],
    "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 Traverse Portal’s own options

Traverse documents two APIs, the Platform API and the Vision Data API, which it provides to its customers. The Platform API's Charge API is described for Performance Center customers, and the documentation does not describe API access for vendors. As a vendor you use the Traverse Portal, where charges, disputes and reversals sit under Vendor Tools.

Signing in to the Traverse Portal

CVS's Traverse Portal is at cvs.traversesystems.com, and you sign in there with your vendor account. With Fous you sign in once through the portal's own sign-in with your own account: 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

The address names the retailer

CVS's Traverse Portal is at cvs.traversesystems.com. A method is built on the portal you sign in to, so you build one for each retailer's portal you use.

45 days to dispute at CVS

CVS compliance fines can no longer be disputed 45 days after the charge deduction date, and after 365 days they can no longer be found in the Traverse Portal.

The charge number tells the program

At CVS, charge numbers end in -OT for OTIF, -SP for Small Parcel and -AS for ASN. A weekly compliance summary email lists the charge numbers to search.

Attachments and Comments are yours to add

In Create Disputes, most fields fill in from the charge number. Attachments and Comments need your input, and the proof needed depends on the metric the charge is for.
