Automate RMS 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.

• Orders waiting in 注文確認待ち, every morning

  Build this

  Starts

  Every day at 8:00, Asia/Tokyo

  Step 1

  Get the orders in status 注文確認待ち.

  Step 2

  Keep the orders that were not there on the last run.

  Step 3

  Email you the list with order number, order date, items, quantity and total.

• Weekly 店舗カルテ report

  Build this

  Starts

  Every Monday at 9:00, Asia/Tokyo

  Step 1

  Read 店舗カルテ for the past 14 days.

  Step 2

  Summarize the last seven days' 売上, アクセス人数, 転換率 and 客単価 against the seven days before.

  Step 3

  Email you the summary with the daily figures underneath.

• Orders in 発送待ち, posted to your warehouse system

  Build this

  Starts

  Every weekday at 14:00, Asia/Tokyo

  Step 1

  Get the orders in status 発送待ち.

  Step 2

  Stop when there are none.

  Step 3

  Post order number, order date, items, quantity and total to your warehouse system's 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 “Get orders by status” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "glogin.rms.rakuten.co.jp/get_orders_by_status",
    "input": {
      "status": "発送待ち",
      "ordered_since": "2026-11-10"
    }
  }'

{
  "status": "completed",
  "data": {
    "status": "発送待ち",
    "orders": [
      {
        "order_number": "100001-20261111-0000012345",
        "order_date": "2026-11-11T09:42:00+09:00",
        "status": "発送待ち",
        "items": "Acme 保温タンブラー 500ml",
        "quantity": 2,
        "total": 6380,
        "currency": "JPY"
      }
    ],
    "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.

RMS’s own options

Rakuten offers RMS WEB SERVICE, an API for shops, documented inside RMS for signed-in shops; each connected system gets its own access setting in RMS. RMS also lists a CSV data download for order and shipping data, and BOSS, an order automation plan from 3,000 yen a month. Analytics such as 店舗カルテ are read in R-Karte.

Signing in to RMS

RMS has two sign-ins. R-Login takes the shop's R-Login ID and password, then each person's own Rakuten member ID and password; 楽天ビジネスログイン takes a Rakuten ID, password and a code sent to Viber. With Fous you sign in once through RMS's own sign-in with your own account, the login is sealed with AES-256, and with R-Login an expired session is signed back in.

Worth knowing

New orders start in 注文確認待ち

You confirm each order and send the サンクスメール (thank-you mail). Once the customer's payment is complete, the order moves to 発送待ち, where you enter the 発送日 and お荷物伝票番号.

Two keys: the shop's and the person's

R-Login needs the shop's key and a personal key. Every user registers their own Rakuten member account, and a ダブルアカウント (outside contractor) is for editing pages in R-Storefront.

Viber codes last two minutes

On 楽天ビジネスログイン a code is valid for 2 minutes, up to 5 codes per attempt. Trusting a PC skips the code for 14 days, in that browser only.

One licence key per connected system

In RMS each connected system has its own row and key. Integrators' guides say a shop can hold two valid licence keys, so an old one is suspended before a new one is issued.
