Automate ACV 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.

• Sold vehicles still waiting for a verified pickup

  Build this

  Starts

  Every weekday at 8:00 Eastern

  Step 1

  Check pickup verification for vehicles sold in the last 14 days.

  Step 2

  Keep the ones still showing Pickup Not Verified at least 3 days after the sale date.

  Step 3

  Email you the list with auction ID, VIN, year, make, model and sale date.

• Title Hub changes, sent to your title team

  Build this

  Starts

  Every weekday at 9:00 Eastern

  Step 1

  Get every auction's title status from Title Hub.

  Step 2

  Keep the auctions whose status changed since the last run.

  Step 3

  Post them to your Slack or DMS webhook, with Upload Denied ones and their notes first.

• Condition report summaries for your buyers' shortlist

  Build this

  Starts

  When your system calls the workflow's webhook with a list of auction IDs

  Step 1

  For each auction ID, read the vehicle's condition report.

  Step 2

  Summarize each vehicle's announcements, mechanical and body findings, OBDII codes and paint meter readings in three lines.

  Step 3

  Email you the summaries, one vehicle per section.

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 pickup verification for sold vehicles” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "app.acvauctions.com/check_pickup_verification",
    "input": {
      "start_date": "2026-11-02",
      "end_date": "2026-11-11",
      "pickup_verification": "Pickup Not Verified"
    }
  }'

{
  "status": "completed",
  "data": {
    "vehicles": [
      {
        "auction_id": "8124410",
        "vin": "1FTEW1EP0NKA00000",
        "year": 2022,
        "make": "Ford",
        "model": "F-150",
        "sale_date": "2026-11-04",
        "pickup_verification": "Pickup Not Verified",
        "verified_at": 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.

ACV’s own options

ACV's support pages document no public API for dealers. What they describe is the website and the ACV app for Apple and Android, plus an Export Data button on the Sold page in My ACV that downloads your sold auctions, or their pickup verification, as a spreadsheet file.

Signing in to ACV

ACV signs you in with the email address you registered with as your username and a password, on the website or in the ACV app. With Fous you sign in once through ACV's own sign-in with your own account: the login is sealed with AES-256 and never shown to your code or AI agents, and an expired session is signed back in.

Worth knowing

Pickup slips are released on a timetable

With an AuctionACCESS ID, the pickup slip is released by 11:00 AM ET the day after checkout. Without one, by 1:30 PM ET 5 calendar days after. Floor plan payments release it right away.

The arbitration window is 10 calendar days

A buyer has 10 calendar days from the sale date to submit a claim, the day the seller accepts counting as day one. ACV Transport bought within 24 hours gives at least 4 days from delivery.

The export writes Verified At in UTC

The Transport Release export dates Verified At in UTC and as day/month/year, so 03/10/2026 is October 3, 2026. The Sold page shows the same scan in your local time zone.

Your title team can have read-only roles

ACV supports read-only roles in the Auctions application for title team members, so they can follow Title Hub. A title status update request covers one title, and ACV typically answers within 2 business days.
