Automate PharmaClik 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.

• Narcotic invoices to sign, every store

  Build this

  Starts

  Every weekday at 8:00

  Step 1

  For each account you name, list the narcotic invoices in Missing Narcotic Signatures.

  Step 2

  Stop when no account has any.

  Step 3

  Email you the invoices, one section per store, so the pharmacist can sign them in PharmaClik.

• Uploaded orders not yet confirmed

  Build this

  Starts

  Every weekday at 11:00 and 15:00

  Step 1

  For each account, list the orders in Order Management that are not Confirmed.

  Step 2

  Keep the orders that were also there on the last run.

  Step 3

  Email you each one with its PO number, order type and upload date.

• Yesterday's invoices, posted to your inventory system

  Build this

  Starts

  Every day at 9:00

  Step 1

  For each account, get the invoices dated yesterday.

  Step 2

  Keep the invoices not seen on the last run.

  Step 3

  Post invoice number, PO number, lines and quantities shipped to your inventory or accounting 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 “List narcotic invoices missing a signature” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "pharmaclik-login.mckesson.ca/get_missing_narcotic_signatures",
    "input": {
      "account": "7004512"
    }
  }'

{
  "status": "completed",
  "data": {
    "invoices": [
      {
        "invoice_number": "INV-40518823",
        "invoice_date": "2026-11-09",
        "po_number": "N1108-A",
        "account": "7004512"
      },
      {
        "invoice_number": "INV-40520117",
        "invoice_date": "2026-11-10",
        "po_number": "N1109-A",
        "account": "7004512"
      }
    ]
  }
}

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.

PharmaClik’s own options

McKesson Canada's Web Services let a pharmacy's own software upload orders and download invoices and the catalogue, with the store's PharmaClik username and password. They work through software that supports them, such as Kroll and PharmaClik Rx. Uploaded orders are still confirmed, and narcotic invoices still signed, on PharmaClik.

Signing in to PharmaClik

PharmaClik's sign-in page starts with a Username field, links to help with a locked account and switches between English and French. One username can reach several store accounts, chosen in the Account Selector. With Fous you sign in once through PharmaClik's own sign-in with your own account: the login is sealed with AES-256 and never returned by the API or written to logs.

Worth knowing

An uploaded order does not ship by itself

An order sent from your pharmacy software only reaches PharmaClik. It ships after someone reviews and confirms it in Order Management, and a narcotic order also needs the pharmacist's signature.

Five days to sign narcotic invoices

The pharmacist signs narcotic invoices in PharmaClik within 5 days of receiving the order. If they are not signed, McKesson halts all narcotic shipments to the store until they are.

Invoices are filed under the Bill to number

Electronic invoices are held under the SAP customer # (Bill to number). A store set up under another store's account needs a username with access to both the Bill to and Ship to accounts.

Duplicate orders are not blocked

McKesson's servers do not prevent duplicate orders, and the PO number is optional on PharmaClik. Give every order a unique PO number so each invoice can be matched to its order.
