  Buildxact is a Melbourne, Australia-headquartered construction estimating and project management SaaS for residential
  builders, remodelers, trade contractors, and building-material suppliers. Founded in 2011, the company operates
  regional offices in Austin, Texas (North America), and serves customers across Australia, New Zealand, the United
  Kingdom, the United States, and Canada. The platform spans the full residential job lifecycle — lead capture, digital
  takeoffs, AI-assisted estimating ("Blu"), customer quoting and e-signatures, supplier/dealer price-list integration,
  purchase orders, scheduling (Gantt), timesheets, variations/change orders, invoicing, and two-way accounting sync with
  Xero and QuickBooks Online. Buildxact exposes a public REST API and webhook surface at developer.buildxact.com,
  available to Merchant and Manufacturer partners as well as customer subscribers, using a Microsoft Azure API
  Management gateway (Ocp-Apim-Subscription-Key + bearer token). Endpoints support OData filtering and sorting, with a
  separate UAT/staging environment. In 2024, Autodesk announced an agreement to acquire Buildxact, positioning the
  product as a residential construction front-end alongside Autodesk's broader AEC portfolio.

    description: >-
      Buildxact's public REST API exposes core construction-job data including estimates and estimate items, with
      related tax-context and reference data. The API is fronted by Azure API Management; every request must carry an
      Ocp-Apim-Subscription-Key header identifying the partner organization and an Authorization: Bearer access token
      scoped to a Buildxact user and tenant. Endpoints follow REST conventions with OData query support — $filter,
      $orderBy, $top, $skip, and $count=true (record total returned via the x-odata-total-count response header). A
      staging environment is available at developer-uat.buildxact.com. Rate-limited at 100 requests per 30-second
      window.

      Buildxact's webhook surface lets partner and customer integrations receive real-time notifications when events
      occur inside the construction-management platform — including Estimate Accepted, Lead Created, and Lead Updated,
      plus additional event types reserved for Merchant and Manufacturer plan tiers. Webhooks are registered from the
      "My Business > API" panel of the Buildxact web app: provide a destination URL, choose events, store the signing
      secret used to verify payload authenticity, and inspect deliveries via the built-in Event Log. Payloads are JSON
      over HTTPS.
