Automate Payapps 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.

• Submitted claims nearing their approval due date

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  Get the progress claims in Submitted status across your projects.

  Step 2

  Keep the claims whose approval due date is in the next three days or has passed.

  Step 3

  Email you the list grouped by project, with claimant, claim number and approval due date.

• Approved claims, posted to your accounting system

  Build this

  Starts

  Every day at 18:00

  Step 1

  Get the progress claims in Approved status and keep those not there on the last run.

  Step 2

  For each one, read the approved claim's totals.

  Step 3

  Post project, contract, claim number, net claim, retention to date and payment due date to your webhook.

• Month-end list of submitted claims for accruals

  Build this

  Starts

  Every month on the 1st at 8:00

  Step 1

  Get the progress claims in Submitted status, not yet fully assessed.

  Step 2

  Group them by project with an AI step.

  Step 3

  Email you the list and post each claim to your finance 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 progress claims 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": "my.payapps.com/get_progress_claims",
    "input": {
      "status": "Submitted",
      "project": "Northwind Medical Centre"
    }
  }'

{
  "status": "completed",
  "data": {
    "claims": [
      {
        "project": "Northwind Medical Centre",
        "contract": "Mechanical services",
        "claim_number": 7,
        "claim_as_at": "2026-10-31",
        "status": "Submitted",
        "claimant": "Acme Air Pty Ltd",
        "respondent": "Globex Construction",
        "submitted_at": "2026-10-28",
        "approved_at": null,
        "approval_due_date": "2026-11-11",
        "payment_due_date": "2026-11-25",
        "invoice_reference": "INV-2207"
      }
    ],
    "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.

Payapps’s own options

Payapps documents a public API for extracting data: projects, contracts and progress claims (payapps), with approved claim totals and PDFs. Its write endpoints were marked deprecated in December 2024, so it reads only. It needs a client ID and secret, and the public pages do not say who can get them or what they cost.

Signing in to Payapps

Payapps now signs people in with Autodesk ID: you enter your email on my.payapps.com, then a 6-digit code sent by email by default, or your organisation's single sign-on when it has one. With Fous you sign in once through Payapps' own sign-in with your own account: the login is sealed with AES-256, the emailed code is handled, and an expired session is signed back in.

Worth knowing

Three statuses, and totals only once approved

A claim not yet submitted is Draft, a submitted claim that is not fully assessed is Submitted, and a fully assessed one is Approved. Payapps produces the approved claim's totals and invoice only for Approved claims.

The public API reads only

Payapps marked its API write endpoints as deprecated on 12 December 2024. Submitting a claim or changing a contract happens in the app itself.

Sign-in moved to Autodesk ID

From 1 February 2026 Payapps moved accounts to Autodesk ID in stages. The default second step is an emailed 6-digit code, and other methods are chosen at profile.autodesk.com.

One login for every counterparty

One Payapps account covers all your projects and the builders you claim from. A subcontractor joins a builder's contract through an email invitation from that builder.
