Automate Expert 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.

• New lender responses on submitted deals

  Build this

  Starts

  Every weekday at 8:00

  Step 1

  For each deal you list, get the lender response from the Lender Response screen.

  Step 2

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

  Step 3

  Email you the approvals, declines and pending responses, with lender, reason and lender notes.

• Condition status changes, posted to your CRM

  Build this

  Starts

  Every weekday at 16:00

  Step 1

  For each accepted deal you list, get the condition status from the Condition Status screen.

  Step 2

  Keep the conditions whose status changed since the last run.

  Step 3

  Post each one, with deal, lender, condition name and status, to your CRM webhook.

• Monday summary of outstanding conditions

  Build this

  Starts

  Every Monday at 7:00

  Step 1

  For each accepted deal you list, get the condition status.

  Step 2

  Keep the conditions that are still open.

  Step 3

  Group them by deal with an AI step and email you the summary.

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 the lender response for a deal” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "expert.filogix.com/get_lender_response",
    "input": {
      "deal": "12 Maple Crescent"
    }
  }'

{
  "status": "completed",
  "data": {
    "deal": "12 Maple Crescent",
    "deal_status": "Approved",
    "responses": [
      {
        "lender": "Northwind Trust",
        "response_type": "Approved",
        "reason": null,
        "lender_notes": "Commitment issued. Conditions to follow.",
        "accepted": false
      }
    ],
    "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.

Expert’s own options

Filogix's pages for brokers describe Expert Broker as the tool for submitting applications to 350+ lenders, managing documents and accessing credit data, and Expert Pro as the one with automations and AI-supported workflows. They mention support for integrations but publish no API or developer documentation for brokers.

Signing in to Expert

Expert's sign-in page asks for the firm code you were given, your username or ID and your password. With Fous you sign in once through Expert's own sign-in with your own account. The login is sealed with AES-256, never returned by the API or written to logs, and a method reads and does only what your account can.

Worth knowing

Statuses update by themselves until Accepted

Expert moves a deal through In Progress, Submitted, Approved or Declined, and Accepted by itself. After that, Ready to Close, Closed, Confirmed, Paid and Complete are set by you.

Conditions only from some lenders

Condition Status and Lender Status appear only for lenders on Express 4.2 or later. Showing the Lender Deal Status is the lender's choice, so it may not appear.

Blank approvals need a manual response

Some lenders send a blank approval and the details by email or fax. The Accept button stays disabled until you add the response by hand.

Accepted and Complete deals are locked

Accepting a lender response stops edits to the mortgage details until you un-accept it. A deal in Complete status is read-only, and changing it depends on your user privileges.
