## Automate VWR.com with a workflow

A [workflow](/product/workflows) 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

Starts: Every weekday at 7:00

1. Get order status for the last month of orders.
2. Keep the orders not yet delivered whose estimated arrival date changed since the last run.
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

Starts: Every day at 18:00

1. Get order status for orders from the last week.
2. Keep the orders that shipped since the last run, and get the documents for each one.
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

Starts: Every Monday at 8:00

1. Check contract price and availability for the catalog numbers you list.
2. Keep the items whose price or availability changed since the last run.
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](/product/methods), 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.

Example request:

```
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"
    }
  }'
```

Example response:

```
{
  "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.

| Option | What it covers | What it takes |
| --- | --- | --- |
| Punch-out and hosted catalogs | Standard or Level II punch-out to VWR.com with real-time price and availability, or a hosted catalog with periodic or live pricing. | An integration project with Avantor's B2B team, connected to your e-procurement or ERP system. |
| Transaction support (EDI or XML) | Purchase orders, order acknowledgements, advance ship notices and invoices, electronically or by email, plus EFT. | An integration project with Avantor. EDI and XML connections need the public web certificates Avantor publishes. |
| Advanced site features | Order Activity Export, Order Approval Workflow, custom catalogs and product blocking. | Activated by Avantor, depending on the arrangements your organization has made with VWR. |
| VWR.com by hand | Order Status, My Orders with certificates, invoices and packing slips, My Quotes, and contract prices in the Shopping Basket. | A Permanent Profile with your Shipping Account Number, approved for Contract Pricing and Availability. |

## 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.

## Frequently asked questions

### Does VWR have an API?

Not a self-serve one. Avantor sets up punch-out, hosted catalogs and EDI or XML transactions for purchase orders, acknowledgements, ship notices and invoices as an integration project with each customer. Order Activity Export depends on your organization's arrangements. The rest is VWR.com by hand.

### Can I see orders I placed by phone or fax?

Yes. Order Status shows every order placed with Avantor, however it was placed. You can search by Shipping Account Number, Order Number, Purchase Order Number or Invoice Number, and the search covers the last 90 days unless you set a date range.

### Where do I download a VWR invoice or certificate of analysis?

In My Orders. Each order links to its certificates, invoices and packing slips. A method you build with Fous can return those links for an order number.

### Why don't I see my contract price on VWR.com?

Contract prices show only once your profile is approved for Contract Pricing and Availability. Under Account Status in My Account, send another request with your organization's information. Avantor takes two business days to approve it.

### Is Fous affiliated with Avantor?

No. Fous is an independent product. You use it with your own VWR.com account, and a method reads and does only what that account can.

Fous is an independent product: it is not affiliated with, endorsed by or sponsored by the operator of VWR (Avantor) (Avantor). The name is used only to say which system this page is about. Something here wrong or out of date? Write to legal@fous.com.
