Automate VWR.com 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.

• Open orders whose estimated arrival date moved

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  Get order status for the last month of orders.

  Step 2

  Keep the orders not yet delivered whose estimated arrival date changed since the last run.

  Step 3

  Email you the list with order number, PO number, status, the old and new date and carrier tracking.

• Shipped orders and their invoices, handed to accounts payable

  Build this

  Starts

  Every day at 18:00

  Step 1

  Get order status for orders from the last week.

  Step 2

  Keep the orders that shipped since the last run, and get the documents for each one.

  Step 3

  Post order number, PO number, invoice numbers and invoice links to your accounting system's webhook.

• Weekly contract price check on your standard items

  Build this

  Starts

  Every Monday at 8:00

  Step 1

  Check contract price and availability for the catalog numbers you list.

  Step 2

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

  Step 3

  Email you the changes, with the old and new price.

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 order status” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "vwr.com/get_order_status",
    "input": {
      "date_range": "last_month"
    }
  }'

{
  "status": "completed",
  "data": {
    "orders": [
      {
        "order_number": "4417203",
        "po_number": "NW-20931",
        "order_date": "2026-11-03",
        "status": "Shipped",
        "shipped_date": "2026-11-05",
        "carrier": "UPS",
        "tracking_number": "1Z4A72E80391847265",
        "estimated_arrival": "2026-11-07"
      }
    ],
    "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.

VWR.com’s own options

Avantor sets up B2B integrations with each customer through an integration project manager: punch-out to VWR.com from your e-procurement system, hosted catalogs, and purchase orders, acknowledgements, ship notices and invoices by EDI, XML or email. It publishes no self-serve API. On the site, extra features such as Order Activity Export depend on your organization's arrangements.

Signing in to VWR.com

VWR.com signs you in with your Login ID, the email address on your profile, and a password, with an option to be remembered on the device. One login can reach several organizations. With Fous you sign in once through VWR.com'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

Order Status covers every order channel

Orders placed by web, phone or fax all show in Order Status. Without a date range the search covers only the last 90 days, so a method for older orders takes dates.

Contract prices need an approved profile

Contract prices and availability show only on a Permanent Profile with a Shipping Account Number that Avantor has approved, which takes two business days. A Guest Profile buys by credit card.

Your orders, unless access is widened

A purchasing manager can see orders for a whole group of buyers only after Avantor enables that access. Otherwise a method sees the orders your own login can see.

One login, several organizations

A login can be linked to more than one organization, each with its own settings. You switch under My Organization in My Profile, so a method can take the organization as an input.
