Automate Autodesk Build 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.

• RFIs and submittals in your court, every project

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  For each project you name, get the RFIs and keep those with your company in Ball in court.

  Step 2

  For the same projects, get the submittals pending action from your company.

  Step 3

  Email you one list per project, with the submittals sorted by required approval date.

• New or revised sheets in a version set

  Build this

  Starts

  Every weekday at 6:30

  Step 1

  For each project, list the sheets in the version set you name.

  Step 2

  Post sheet number, title, version, version set and discipline to your webhook.

• Submittals due for approval in the next 14 days

  Email you the list grouped by project and spec 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 “Get RFIs and who has the ball in court” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "acc.autodesk.com/get_rfis",
    "input": {
      "project": "Northwind Medical Office Building",
      "status": "Open in review"
    }
  }'

{
  "status": "completed",
  "data": {
    "project": "Northwind Medical Office Building",
    "rfis": [
      {
        "number": "112",
        "title": "Duct routing conflict at level 3 corridor",
        "status": "Open in review",
        "ball_in_court": [
          "Acme Mechanical"
        ],
        "submitted_for_review_on": "2026-11-06",
        "rfi_placement": "M-301 Level 3 HVAC Plan"
      }
    ],
    "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.

Autodesk Build’s own options

Autodesk Platform Services has APIs for RFIs, submittals and sheet exports, and they act as the signed-in user. An app reaches an account only after that account's admin adds its client ID under Custom Integrations, so a subcontractor invited to a general contractor's account needs that contractor's admin to do it.

Signing in to Autodesk Build

With Fous you sign in to Autodesk Build once yourself, 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. A method reads and does only what your account can on your projects.

Worth knowing

The ball in court moves with the status

An RFI that is Open in review is with its reviewers, and one that is Open answered is back with the managers. A method that reads Ball in court shows which RFIs wait on you.

Submittals name who acts in two places

A submittal shows Pending review from on its workflow bar and Pending action from as a column in the list. Filter on the list column when you want every item waiting on your company.

Sheet exports are capped at 1000

A sheet export, in the browser or through Autodesk's API, holds at most 1000 sheets and comes out as PDF. The API's download link expires after one hour.
