Automate LGY Hub 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.

• Pending COEs that VA has decided, every morning

  Build this

  Starts

  Every weekday at 8:00

  Step 1

  For each Veteran in your pipeline, look up the COE status in Search/Automated Certificate of Eligibility.

  Step 2

  Keep the Veterans whose status changed since the last run.

  Step 3

  Email you the list with your loan reference and the old and new status for each Veteran.

• 90-day user validation, before the window closes

  Build this

  Starts

  Every Monday at 9:00

  Step 1

  Read the Validate Users list in WebLGY's Admin menu.

  Step 2

  Stop the run when no users are listed.

  Step 3

  Email you the validation window and the users listed for validation.

• New users waiting for activation, posted to your IT queue

  Build this

  Starts

  Every weekday at 10:00

  Step 1

  Read the Activate Users list in WebLGY's Admin menu.

  Step 2

  Keep the users who were not there on the last run.

  Step 3

  Post each new user's details, as the page shows them, to your ticketing 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 “Look up a Veteran's COE status” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "lgy.va.gov/get_coe_status",
    "input": {
      "veteran_ssn": "000-00-0000",
      "year_of_birth": "1984"
    }
  }'

{
  "status": "completed",
  "data": {
    "status": "Pending",
    "status_detail": "Awaiting Supporting Documentation",
    "existing_eligibility_record_on_file": true
  }
}

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.

LGY Hub’s own options

VA's developer portal lists three Loan Guaranty APIs. The Loan Review API is in production and is the required way to send Full File Loan Review documents; the Guaranty Remittance API is listed as sandbox only. The portal lists no API for COE searches or WebLGY user administration, which are done in WebLGY.

Read on November 12, 2026: VA API Platform: Loan Guaranty APIs, VA Home Loans Transformation Hub, LGY Help Center FAQ.

Signing in to LGY Hub

LGY Hub signs external users in through AccessVA with ID.me: an email address and password, then a second step by text message, authentication app, voice call or a U2F security key. Each person needs their own account. With Fous you sign in through LGY Hub's own sign-in with your own account, and the login is sealed with AES-256, never returned by the API, and never seen by your code or AI agents.

Worth knowing

FFLR files go through the API only

Since November 4, 2024, LGY no longer accepts Full File Loan Review files uploaded to WebLGY Correspondence. FFLR documents must be sent with the Loan Review API, with a 100 MB limit per file.

Two 90-day rules keep accounts alive

A user who does not log in to LGY Hub for 90 days is deactivated. Your Lender/Servicer Admin must also validate every user every 90 days, in a 15-day window shown on Validate Users.

Do not resubmit a Pending COE

A Pending COE (Awaiting Supporting Documentation) must not be applied for again, and VA notifies you by email. When ACE cannot issue the COE, a Regional Loan Center decides within 5 business days.

Releases take WebLGY offline at night

For LGY Release 27.0.1 on November 12, 2026, LGY Hub and WebLGY are unavailable from 9:00 p.m. EST until the release is complete. Keep scheduled workflows clear of release evenings.
