Turn Exostar's Supply Chain Platform into an API

Automate Exostar 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.

• Discrete orders with no invoice lines, every partner

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  For each partner application you name, find the orders not yet invoiced.

  Step 2

  Keep the orders whose Invoice Info tab shows no invoice lines.

  Step 3

  Email you the list, one section per partner, with each order's schedule lines and quantities.

• 2FA credential expiry, checked weekly

  Build this

  Starts

  Every Monday at 8:00

  Step 1

  Check the 2FA credentials and applications on the MAG Dashboard.

  Step 2

  Stop when the credential expires more than 30 days from today.

  Step 3

  Email you the credential strength, the expiry date and your applications with their status.

• Today's invoices, posted to your accounting system

  Build this

  Starts

  When your system calls the workflow's webhook with the partner and today's order numbers

  Step 1

  For each order number you send, look up its invoices in that partner's application.

  Step 2

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

  Step 3

  Post invoice number, order number, invoice type, supplier invoice date and lines 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 “Find orders not yet invoiced” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "portal.exostar.com/find_orders_not_invoiced",
    "input": {
      "partner": "Acme",
      "order_number": null
    }
  }'

{
  "status": "completed",
  "data": {
    "partner": "Acme",
    "orders": [
      {
        "order_number": "4500812",
        "buyer_contact": "Acme Procurement, Plant 2",
        "supplier_contact": "Northwind Accounts Receivable",
        "invoice_lines_found": false,
        "schedule_lines": [
          {
            "line": "1.1",
            "item": "Bracket, machined, 7075-T6",
            "quantity": 40,
            "unit_price": 18.5
          }
        ]
      }
    ],
    "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.

Exostar’s own options

Exostar describes SupplyLine, its supply chain collaboration platform for aerospace and defense, as exchanging purchase orders, advanced shipping notices, acknowledgments and demand schedules, and says it connects with nearly any ERP system, with Exostar's tools and support where no ready connection exists. No price is published. Day to day, you work in each partner's application behind the Managed Access Gateway.

Signing in to Exostar

You sign in to Exostar's Managed Access Gateway with your Exostar User ID, and partners like Boeing require each supplier user to hold a two-factor credential, such as an Exostar OTP hardware token. One MAG account opens every partner application you are granted. With Fous you sign in through Exostar's own sign-in with your own account, and the login is sealed with AES-256 and never returned by the API.

Worth knowing

One Supply Chain Platform per partner

The MAG Dashboard lists each partner's application separately, such as Supply Chain Platform - Boeing (BSCP). An Application Administrator approves access to each one, and each method you build takes the partner as an input.

Invoice numbers have partner rules

For Boeing, invoice numbers allow letters, numbers, hyphens and underscores only, up to 22 characters (16 for Boeing ISC). A reused number needs a suffix such as A or -1.

Dates and quantities are checked

Boeing requires the Supplier Invoice Date as YYYY-MM-DD and rejects back-dated invoices. A decimal in the Quantity field causes a rejection, so invoice quantities are whole numbers.

2FA credentials are bought and expire

OTP credentials are bought from Exostar's web store, during First Time Login or later under My Account, Manage OTP. The MAG Dashboard shows the credential's strength and its expiry date.
