## Automate ARMS Automotive 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.

### Renters whose repair status has not been updated

Starts: Every weekday at 7:30

1. Get the Vehicle List from ARMS Automotive.
2. For each renter, read the repair status and labor hours on the Vehicle Detail page.
3. Keep the renters whose repair status and labor hours have not changed since the last run.
4. Email you the list with renter's name, repair status and labor hours.

### Weekly rental length report

Starts: Every Monday at 8:00

1. Get the open and closed rentals report.
2. Compare your average rental length with the market's and with last week's run.
3. Email you a short summary with the open and closed counts.

### Repair status from your shop system

Starts: When your system calls the workflow's webhook with a renter's name and repair status

1. Update the repair status and labor hours on that renter's Vehicle Detail page.
2. Read the Vehicle Detail page back to confirm what was saved.
3. Post renter's name, repair status and labor hours to your shop 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](/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 the Vehicle List” 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": "www.armsauto.com/get_vehicle_list",
    "input": {}
  }'
```

Example response:

```
{
  "status": "completed",
  "data": {
    "vehicles": [
      {
        "renter_name": "Dana Acme"
      },
      {
        "renter_name": "Lee Northwind"
      },
      {
        "renter_name": "Sam Globex"
      }
    ],
    "count": 3
  }
}
```

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.

## ARMS Automotive’s own options

Enterprise lists Replacement Rental APIs on its developer site for insurance, collision repair and fleet partners: messages with the rental branch, the rental from authorization to payment, and rental data. Access is requested through your Enterprise account manager, and no public specification is shown. Shops otherwise update repair status in ARMS Automotive itself.

| Option | What it covers | What it takes |
| --- | --- | --- |
| Replacement Rental APIs | Send and receive messages with the rental branch, manage rentals from authorization to payment, and view data such as average length of rental. | A partner request through your Enterprise account manager. No public pricing or specification. |
| Consumer status notifications | Status notifications by text or email from your shop to your customers, sent from ARMS Automotive. | Part of the ARMS Automotive Suite. Some features may not be available in the UK or Ireland. |
| ARMS Automotive by hand | The Vehicle List, Vehicle Detail updates, Create Reservation and the open and closed rentals reporting. | A User ID and password from enrollment, completed with an Enterprise representative. |

## Signing in to ARMS Automotive

ARMS Automotive signs you in with the User ID and password you chose at enrollment, and you enter them every time you open the system. No second step is documented. With Fous you sign in once through ARMS Automotive's own sign-in with your own account: the login is sealed with AES-256, and an expired session is signed back in.

## Worth knowing

- **Enrollment goes through an Enterprise branch**: You start with Online Enrollment, but an Enterprise representative has to help you finish it. The FAQ says to call 1 800 Rent A Car and ask for the Branch or Assistant Branch Manager.
- **Your status updates reach the insurer**: Repair status and labor hour updates you make in ARMS Automotive go to Enterprise, which passes them on to the insurance company.
- **Your shop system may already send the date**: ARMS Automotive Exchange can work with a shop's management system to send estimated completion dates and status details to Enterprise. Check with your management system provider before you build an update method.
- **Reservations go to the branch**: Create Reservation on the Vehicle List sends the request to the Enterprise branch, which contacts the customer when it needs more information. Rate questions go to your local branch.

## Frequently asked questions

### Does ARMS Automotive have an API?

Not a public one. Enterprise lists Replacement Rental APIs on its developer site for insurance, collision repair and fleet partners, and you request access through your Enterprise account manager. Without that, repair status is updated in ARMS Automotive itself.

### How do I update a vehicle's repair status in ARMS Automotive?

Open the renter from the Vehicle List by clicking the Renter's Name or Update column, then update the vehicle status data on the Vehicle Detail page. Repair status updates go to Enterprise and the insurance company.

### Can I create a rental reservation for a customer?

Yes. Click Create Reservation at the top of the Vehicle List, fill in the required fields and click Send Reservation. The Enterprise branch receives it and contacts the customer if it needs more information.

### What does the ARMS Automotive Suite include?

Three modules: repair status and labor hour updates sent to Enterprise and insurers, shop reporting of open and closed rentals with your average rental length against the market, and text or email status notifications to your customers.

### Is Fous affiliated with Enterprise Mobility?

No. Fous is an independent product. You use it with your own ARMS Automotive 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 ARMS Automotive Suite (Enterprise Mobility). 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.
