# Turn the RTX Supply Chain Platform into an API

> Read new and updated purchase orders, reconfirmation requests and invoice line states from RSCP with one API call each. A workflow can check the Order Summary every weekday morning and email you the new schedule lines waiting for your response.

Works with your own RTX Supply Chain Platform account. Fous is an independent product.

## What you can build on RSCP

### Get new and updated purchase orders

Reads the purchase orders in the New and Updated states from the Order Summary on My Workspace, down to each request schedule.

- Takes: State (New or Updated), order number (optional)
- Returns: Order number, line, schedule, state, request delivery date, request qty, unit price, Early Shipment flag, changed fields

### Get reconfirmation requests

Reads Reconfirmation-Purchase Orders in Supply Network Exceptions on My Workspace, with the High, Medium or Low level of each schedule.

- Takes: Level (High, Medium, Low or all)
- Returns: Order number, line, schedule, request delivery date, quantity, reconfirm level

### Check invoice line states

Searches invoices under Order Management and reads each line's Line State and Status Message.

- Takes: Invoice number or order number, created since (optional)
- Returns: Invoice number, order number, line, line state, status message, invoice type (credit or debit), amount

### Accept purchase order schedule lines

Opens a purchase order, selects the schedule lines you name and responds Accept, then reads the order state and the Downloaded to Buyer flag.

- Takes: Order number, schedule lines
- Returns: Order number, schedule lines accepted, order state, downloaded to buyer

## Automate RSCP 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.

### New and updated purchase orders, every weekday

Starts: Every weekday at 7:00

1. Get the purchase orders in the New and Updated states from the Order Summary.
2. Keep the schedule lines that were not there on the last run.
3. Email you the list grouped by order, with the changed fields named.

### Monthly reconfirmation requests, by level

Starts: Every month on the 2nd at 8:00

1. Get the reconfirmation requests at every level from Supply Network Exceptions.
2. Have an AI step group them by level, High first.
3. Post the list to your planning system's webhook and email you the High ones.

### Invoice line states, handed to accounting

Starts: Every weekday at 17:00

1. Check the line states of the invoices sent in the last 90 days.
2. Keep the lines whose Line State changed since the last run.
3. Post invoice number, line, line state and status message to your 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](/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 new and updated purchase orders” 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": "portal.exostar.com/get_new_and_updated_purchase_orders",
    "input": {
      "state": "Updated"
    }
  }'
```

Example response:

```
{
  "status": "completed",
  "data": {
    "schedules": [
      {
        "order_number": "7712045",
        "line": "10",
        "schedule": "1",
        "state": "Updated",
        "request_delivery_date": "2027-01-18",
        "request_qty": 24,
        "unit_price": 412.5,
        "early_shipment": "No",
        "changed_fields": "Request Delivery Date, Request Qty"
      }
    ],
    "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.

## RSCP’s own options

Exostar's RSCP Product Guide describes a web application reached through Exostar's Managed Access Gateway. It offers Excel (.xls) uploads and downloads for selected transactions and email alerts, and it does not describe an API for suppliers.

| Option | What it covers | What it takes |
| --- | --- | --- |
| Uploads | Excel files for purchase orders, stocking units, receipts and invoices, from the Uploads menu. | XLS files only; the stocking unit template is on the RSCP Training Resources page. |
| Downloads | Excel files for purchase orders, shipments, receipts and invoices, with saved download settings for the field order. | An RSCP account; run from the Downloads menu. |
| Email alerts | Alerts for document types and states, such as PO changes found every four hours and stocking units Packed, Not Shipped. | A subscription under Email Alert Subscriptions. |
| RSCP by hand | My Workspace, Exceptions, Order Management, Master Data and Reports in the browser. | An approved Exostar MAG account with a SOTP credential. |

## Signing in to RSCP

RSCP is reached through Exostar's Managed Access Gateway (MAG): you need an approved MAG account, and RSCP requires a SOTP (Soft One Time Password with proofing) credential. RTX's supplier training describes it as a one-time password sent by SMS to a registered phone. With Fous you sign in through Exostar's own sign-in with your own account. The login is sealed with AES-256, never returned by the API or logged.

## Worth knowing

- **A response reaches RTX only when complete**: A PO is sent to RTX only when every schedule line has left New and Updated. RSCP checks every 15 minutes and then sets Downloaded to Buyer to Yes.
- **The Early Shipment flag limits Accepted**: With the flag at Yes, Accepted allows any earlier date or up to seven days later. At No, it allows seven days either way. With no flag, Accepted needs the exact Request Delivery Date.
- **RSCP archives and purges records**: Closed, cancelled and rejected PO lines archive 60 days after the header last changed and are purged after 180 days. Paid, Rejected or Approved invoice lines archive after 90 days.
- **Payment status is not the payment**: Payments are not processed through RSCP, and only some RTX business units send invoice payment statuses. A Total Amount can cover several invoices or POs.

## Frequently asked questions

### Does the RTX Supply Chain Platform have an API?

Exostar's RSCP Product Guide does not describe one for suppliers. It offers Excel uploads for purchase orders, stocking units, receipts and invoices, Excel downloads for purchase orders, shipments, receipts and invoices, and email alerts. Everything else happens in the web application.

### How do I find purchase order changes in RSCP?

Open the Updated row of the Order Summary on My Workspace. RSCP looks for changed orders every four hours and emails an alert, and it highlights changed Stat/Contract Date, Request Delivery Date, Request Qty and Unit Price in yellow. The Full Print PDF marks every changed field with a red asterisk.

### Can I create stocking units or invoices in bulk?

Yes, by Excel upload. The Uploads menu takes XLS files for purchase orders, stocking units, receipts and invoices. For stocking units, the template is on the RSCP Training Resources page and you wait in Inbox Status until it shows Completed. Uploaded invoices can also be Open-Unreferenced.

### Why has my purchase order response not reached RTX?

Most often because some schedule lines are still New or Updated. RSCP sends a PO only when all lines are answered. Search Purchase Orders with Supplier Responded set to No to find the partial ones.

### Is Fous affiliated with RTX or Exostar?

No. Fous is an independent product. You use it with your own Exostar 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 RTX Supply Chain Platform (RTX, hosted by Exostar). 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.
