Automate PartsTech 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.

• The day's submitted orders, posted to accounting

  Build this

  Starts

  Every weekday at 18:00

  Step 1

  Get the orders submitted today from the Orders page.

  Step 2

  For each order, get its part list with quantities, prices and core charges.

  Step 3

  Post each order with its supplier, vehicle, parts and total to your accounting system's webhook.

• Price changes on your stock parts, by supplier

  Build this

  Starts

  Every Monday at 7:00

  Step 1

  For each part number on your stock list, check price and availability at every connected supplier.

  Step 2

  Keep the prices that changed since the last run.

  Step 3

  Email you the changes, one section per part number.

• Weekly parts spend by supplier

  Build this

  Starts

  Every Monday at 8:00

  Step 1

  Get last week's orders from the Orders page.

  Step 2

  Group them by supplier and by who placed them, with the order totals added up.

  Step 3

  Email you the summary with the five largest orders listed.

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” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "app.partstech.com/get_orders",
    "input": {
      "date_from": "2026-11-10",
      "date_to": "2026-11-11",
      "status": "Submitted"
    }
  }'

{
  "status": "completed",
  "data": {
    "orders": [
      {
        "order_number": "A-58213",
        "status": "Submitted",
        "submitted_at": "2026-11-11T09:42:00-05:00",
        "supplier": "Northwind Auto Parts, Elm St",
        "vehicle": "2019 Ford F-150",
        "vin": "1FTEW1E50KFA00000",
        "placed_by": "Service desk",
        "parts_count": 3,
        "order_total": 286.47
      }
    ],
    "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.

PartsTech’s own options

PartsTech offers an API to software developers under its API agreement: catalog search, availability, pricing and ordering, with fees listed on an order form. A shop gets a Username and API key on its My profile window, used to connect PartsTech to one of the 35+ shop management systems it integrates with. A PartsTech account, with its search and Orders page, is free.

Signing in to PartsTech

PartsTech accounts are created with an email address and a password, or with a Google account. Each shop location has its own account, Username and API key. With Fous you sign in once through PartsTech's own sign-in with your own account: the login is sealed with AES-256, never returned by the API, and an expired session is signed back in.

Worth knowing

One account per location

Each location needs its own PartsTech account, Username and API key, created with a different email address. A method reads only the account it was signed in with, so each location is signed in separately.

Suppliers must be connected first

You see inventory and order only from suppliers your shop is connected to. Some supplier connections are approved instantly, others go through a manual review that can take up to two weeks.

Fitted parts need a vehicle

Keyword and category searches for fitted parts ask for a vehicle to confirm fitment. Part number searches do not, which makes the part number the simplest input for a price check.

PO number and delivery are per supplier

The cart is organized by supplier, and each supplier gets its own PO Number, Delivery Method and Message to store. A placed order appears on the Orders page with a status of Submitted.
