Automate Reece maX 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.

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 “Check trade prices and branch stock” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "reece.com.au/check_prices_and_stock",
    "input": {
      "products": [
        "Copper tube 15mm",
        "Ball valve 20mm"
      ]
    }
  }'

{
  "status": "completed",
  "data": {
    "account": "Acme Plumbing",
    "products": [
      {
        "product_code": "1048213",
        "description": "Copper tube 15mm type B, 6 m length",
        "trade_price": 48.9,
        "unit": "Each",
        "currency": "AUD",
        "stock_by_branch": {
          "Northside": 64,
          "Westside": 12
        }
      }
    ]
  }
}

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.

Reece maX’s own options

Reece does not publish an API for maX. It connects maX with listed job management and accounting software, such as Fergus, Simpro, AroFlo, ServiceM8, FieldPulse, Xero and MYOB, to automate pricing, ordering and invoicing. You can also download a price file from maX and upload it into your own system.

Signing in to Reece maX

maX is for Reece trade account customers: you sign up with your trade account, your admin can give you access to the team account, and one login can switch between several accounts. With Fous you sign in once through maX's own sign-in with your own login. It is sealed with AES-256 and never shown to your code or agents, and an expired session is signed back in.

Worth knowing

One login, several trade accounts

maX lets you switch between your accounts and request access to an employer's account. A method can take the trade account as an input, and a workflow can loop over each one.

Price files are downloaded, then uploaded

For a job management system such as Fergus, Reece's steps are to download the latest price file from maX and upload it into the system, for example to Price Books.

Integrations are switched on in the other product

You link maX from the job management or accounting software, usually under Settings, Integrations, Select Reece maX. AroFlo links it under Settings, Site Administration, Add-Ons, Supplier Catalogues.
