Turn the Sonepar Onlineshop into an API

What you can build on the Onlineshop

• Get orders from the Bestellverwaltung

  Build this

  Reads the Bestellverwaltung (order management) in Mein Kundenkonto for a date range: each order's dates, status, Kommission, invoice number and tracking.

  Takes

  From date, to date

  Returns

  Order number, order date, status, Kommission, invoice number, tracking, pickup or delivery

• List Rückstände with their Liefertermine

  Build this

  Reads the items in Rückstand (ordered, not yet deliverable) and the Liefertermin shown on each open position in the Bestellverwaltung.

  Takes

  Nothing

  Returns

  Order number, order date, Kommission, Bestellzeichen, article number, description, open quantity, delivery date

• Check prices and availability

  Build this

  Searches the shop for each article number or EAN, reads the price and cheapest Staffelpreis, and the availability and note shown on the product page.

  Takes

  Article numbers or EANs

  Returns

  Article number, description, your price, cheapest Staffelpreis, availability, availability note

• Put articles in the Warenkorb with a Kommission

  Build this

  Adds a list of articles and quantities to the Warenkorb, sets the Kommission and Bestellzeichen, and leaves it ready to order or send for approval.

  Takes

  Article numbers and quantities, Kommission, Bestellzeichen

  Returns

  Basket lines, prices, availability, basket total

Automate the Onlineshop 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.

• Rückstände with changed Liefertermine, every morning

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  List the Rückstände with their Liefertermine.

  Step 2

  Keep the positions whose Liefertermin changed since the last run, or that are new.

  Step 3

  Email you the list grouped by Kommission, so the site teams can plan.

• New invoice numbers, handed to accounting

  Build this

  Starts

  Every weekday at 18:00

  Step 1

  Get the orders from the Bestellverwaltung for the last 30 days.

  Step 2

  Keep the orders that have a Rechnungsnummer they did not have on the last run.

  Step 3

  Post order number, order date, Kommission and Rechnungsnummer to your accounting system's webhook.

• Weekly price and availability check for your core articles

  Build this

  Starts

  Every Monday at 6:30

  Step 1

  Check prices and availability for the article numbers you keep in your list.

  Step 2

  Keep the articles whose price or availability changed since the last run.

  Step 3

  Post the changes to your ERP'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 “Get orders from the Bestellverwaltung” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "sonepar.de/get_orders",
    "input": {
      "from_date": "2026-11-02",
      "to_date": "2026-11-11"
    }
  }'

{
  "status": "completed",
  "data": {
    "orders": [
      {
        "order_number": "4500318822",
        "order_date": "2026-11-10",
        "status": "In Bearbeitung",
        "kommission": "Northwind Lagerhalle 3",
        "invoice_number": null,
        "tracking_url": "https://tracking.example.com/00340434161094",
        "pickup_order": false
      }
    ]
  }
}

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 Onlineshop’s own options

Sonepar connects your trade software or ERP to the Onlineshop through Shop-Schnittstellen: OCI and IDS to order from your own system, UGL and EDI to exchange orders, delivery notes and invoices, and Open Masterdata for product data. Each is set up with Sonepar's support team and your software vendor. Without one, you have the shop itself.

Signing in to the Onlineshop

The Onlineshop asks you to choose your Sonepar company and enter your Kunden-Nr., Benutzerkennung and password, or a verified email address and password. Too many wrong passwords lock the login. With Fous you sign in once through the shop'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

Invoice downloads are for Kunden-Admins

Rechnungen and Lieferscheine download as PDF from the Bestellverwaltung, but Sonepar's release note gives that right to Kunden-Admins only. Sign in with an admin user if a method needs the PDFs.

Liefertermine update once a day

The Liefertermin on a backordered position is refreshed daily from Sonepar's ERP, so one check a day is enough.

Status filter only for SAP orders

The Bestellverwaltung can filter by Auftragsstatus for SAP orders but not for EVA orders, so build the method to read the status from each order instead of relying on the filter.

Invoice cadence is set per customer

Invoices come per order, per weekly Rechnungslauf or monthly, as agreed with your Sonepar location. An Einzelrechnung for one order can be chosen in the Warenkorb.
