Automate the Partner 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 rejection letters, every partner number

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  For each partner number you name, get the rejection letters from the last 30 days.

  Step 2

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

  Step 3

  Email you each one with partner invoice number, company and rejection reason.

• BMW payments, posted to your accounting system

  Build this

  Starts

  Every weekday at 18:00

  Step 1

  For each partner number, get the Payments report for today.

  Step 2

  Stop when there are none.

  Step 3

  Post payment date, amount, currency and the invoice numbers paid to your accounting webhook.

• Weekly invoice status summary by BMW company

  Build this

  Starts

  Every Monday at 8:00

  Step 1

  For each partner number, get the invoice statuses for documents dated in the last 60 days.

  Step 2

  Keep the invoices whose status changed since the last run.

  Step 3

  Group them by BMW company and email you the summary.

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 invoice statuses” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "b2b.bmw.com/get_invoice_statuses",
    "input": {
      "company": "A1",
      "partner_number": "12345610",
      "document_date_from": "2026-10-01",
      "document_date_to": "2026-11-11"
    }
  }'

{
  "status": "completed",
  "data": {
    "company": "A1",
    "partner_number": "12345610",
    "invoices": [
      {
        "partner_invoice_number": "NW-2026-0418",
        "document_date": "2026-10-14",
        "invoice_status": "Paid"
      }
    ],
    "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 Partner Portal’s own options

BMW Group's eInvoicing pages list no API for suppliers. Invoices and credit notes go to BMW as EDI files or are typed into eCap in the eDocument Portal, and BMW calls its standard solutions free of charge. Payment advice comes back as a PDF or as VDA 4988, and invoice status, payments and rejections are read in My Reports.

Signing in to the Partner Portal

Portal Login asks for a User Name and Password. One login (Name.Surname) works for every supplier number and plant code it has been approved for. With Fous you sign in once through the Partner Portal's own sign-in with your own account: the login is sealed with AES-256, and an expired session is signed back in.

Worth knowing

Access is per supplier number and plant code

You register for each 8-digit supplier number: 6 digits plus a 2-digit plant code. A user registered on 123456-10 sees only plant code -10, so a method takes the partner number as an input.

Submitted invoices appear hours later

After Submit Document there is no confirmation email. The document is available for download in the Documents Overview within about 1 to 4 hours.

The delivery / service number depends on type

Serial material uses the delivery note number, work under contract the 8-digit number on the completion certificate, other services the order number plus a consecutive number. A missing order number may get the invoice rejected.

eCap attachments are limited

eCap takes at most 4 attachments of up to 2 MB each, as pdf, png, jpeg or tiff. For BMW Mexico (company code LY) the order and delivery note numbers go on each line item.
