Automate 1link 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.

• Authorised jobs not yet invoiced, every morning

  Build this

  Starts

  Every weekday at 8:00

  Step 1

  Get the jobs listed under payment not requested.

  Step 2

  Keep the jobs whose authorised date is more than 20 days ago, before the authorisation can lapse.

  Step 3

  Email you the list, grouped by fleet.

• New fleet queries on jobsheets, to the workshop

  Build this

  Starts

  Every 30 minutes

  Step 1

  Check jobsheet authorisations and queries submitted in the last 7 days.

  Step 2

  Keep the jobsheets that were queried and were not queried on the last run.

  Step 3

  Post each one, with fleet, vehicle registration and query text, to your Slack or DMS webhook.

• New service bookings, into your workshop diary

  Build this

  Starts

  Every 15 minutes

  Step 1

  Get the service bookings from fleets for the next 14 days.

  Step 2

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

  Step 3

  Post each booking to your DMS or diary 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 jobs with payment not requested” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "1link.co.uk/get_jobs_payment_not_requested",
    "input": {
      "fleet": "Acme Leasing"
    }
  }'

{
  "status": "completed",
  "data": {
    "jobs": [
      {
        "job_reference": "SN-48213",
        "fleet": "Acme Leasing",
        "vehicle_registration": "AB21 XYZ",
        "authorised_date": "2026-10-19",
        "authorised_amount": 412.6,
        "currency": "GBP",
        "status": "Authorised"
      }
    ],
    "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.

1link’s own options

Since March 2025 epyx offers garage users a free Authorisation and Invoice Interface that moves jobs and invoices between your dealer management system and 1link, so you can submit, gain authorisation and invoice without rekeying. It works only once your DMS provider has built its side. The APIs epyx lists for driver booking are a paid service for fleet operators.

Read on November 12, 2026: Interface now available for garages, 1link Service Network for garages, 1link Service Network for fleets.

Signing in to 1link

Garages sign in to 1link Service Network at www.1link.co.uk, where the Sign in link on epyx's site leads. With Fous you sign in once through 1link's own sign-in with your own account: the login is sealed with AES-256, code and AI agents never see it, and an expired session is signed back in.

Worth knowing

Only invoices raised in 1link get paid

Fleet operators can only pay invoices created within 1link Service Network. An invoice raised only in your DMS cannot be matched to the job authorisation, so it is not paid.

Authorisations expire

An authorisation typically expires after 30 days, though this varies by fleet. Invoice before then and you avoid asking the fleet to authorise the job again.

Invoiced means the status says Invoiced

A job is not invoiced until its status changes to Invoiced. Payment not requested on the homepage shows in red while jobs are still waiting to be invoiced through 1link.

The interface depends on your DMS

The free Authorisation and Invoice Interface works only when your DMS provider has built its side of it. epyx says a few DMS companies already provide this.
