Houzz Pro API
Houzz Pro is an all-in-one business management platform for construction, remodeling, and design professionals, spanning estimates, takeoffs, project management, invoicing, online payments, CRM, and lead generation. An unofficial API lets you programmatically pull estimates, proposals, invoices, payments, projects, clients, leads, and schedules—and push updates like new estimates, change orders, invoices, and time entries back into Houzz Pro.
What is Houzz Pro?
Houzz Pro is an all-in-one business management platform for construction, remodeling, and design professionals—builders, remodelers, interior designers, architects, painters, and specialty contractors. It consolidates the workflow from planning and design through project management and financials, so pros can generate estimates and proposals, run takeoffs and 3D floor plans, track selections and procurement, manage schedules and daily logs, invoice clients and collect online payments, and capture and nurture leads from a single system.
Core product areas include:
- Planning & Design (3D floor plans, takeoffs, mood boards, product clipper and library, selections, contracts and bid management)
- Project Management (scheduling, task assignments, daily logs, procurement, time and expense tracking, client and subcontractor dashboards)
- Financial Suite (estimates, proposals, change orders, invoices, online payments, financial reporting, homeowner financing)
- CRM & Marketing (sales pipeline, lead generation, custom websites, email marketing, premium profiles, targeted advertising)
- Integrations (QuickBooks Online, Gmail, Google Calendar, Google Drive, Gusto payroll, GreenSky financing, Zapier)
Common data entities:
- Estimates, Proposals, Bids, Selections, Takeoffs
- Invoices, Payments, Change Orders, Retainers, Financial Reports
- Projects, Schedules, Tasks, Daily Logs, Procurement Orders
- Clients, Leads, CRM Pipeline Stages, Contacts
- Time Entries, Expenses, Subcontractors, Products/Library Items
The Houzz Pro Integration Challenge
Contractors and design firms run their day-to-day business in Houzz Pro, but turning its web-and-mobile workflows into API-driven automation is non-trivial:
- No public developer API: Houzz Pro exposes pre-built integrations (QuickBooks, Gmail, Google Calendar/Drive, Gusto, Zapier) rather than a general-purpose API, so custom data access means working through the authenticated app
- One-way, scoped syncs: The QuickBooks connection pushes approved documents and payments one direction on a fixed cadence, leaving no way to read or write the full project, lead, and selection data programmatically
- Mobile-first data capture: Daily logs, photos, time tracking, and field updates are entered through the mobile app, so portions of the dataset live behind app-only flows
- Document-centric financials: Estimates, proposals, change orders, and invoices move through approval and payment states that downstream systems need to track precisely
- Fragmented lead sources: Leads arrive from the Houzz marketplace, custom websites, Gmail, and Zapier connectors, making a unified, queryable lead feed hard to assemble
- Session and authentication handling: Headless automation must manage login, session continuity, and any verification challenges that a portal-driven product imposes

Supergood reverse-engineers the authenticated Houzz Pro web and mobile flows to deliver a resilient, programmatic API layer for your account—covering estimates, projects, financials, leads, and schedules across the platform.
- Handles username/password login and any verification challenges securely in a managed session
- Maintains session continuity with automated refresh and change detection
- Normalizes responses across estimates, invoices, projects, leads, and schedules so you integrate once and rely on consistent objects
- Supports both reads and writes—pull project and financial data out, push new estimates, change orders, invoices, and time entries back in

Frequently asked questions
Houzz Pro offers pre-built integrations—QuickBooks Online, Gmail, Google Calendar and Drive, Gusto, GreenSky, and Zapier—rather than a general-purpose public developer API. Supergood provides a programmatic API layer over your authenticated account so you can read and write the full data set.
Estimates, proposals, change orders, invoices, payments, projects, schedules, tasks, daily logs, procurement orders, clients, leads, time entries, and expenses are all exposed through a single normalized API surface.
Yes. The API supports both reads and writes, so you can create estimates and proposals, post change orders and invoices, and write time entries and expenses back into the platform.
The native QuickBooks connection is a one-way, scoped sync of approved financial documents on a fixed cadence. Supergood gives you full, bidirectional, programmatic access across financials, projects, leads, and schedules—not just the documents QuickBooks receives.
Daily logs, photos, time tracking, and field updates entered through the Houzz Pro mobile app are surfaced through the same authenticated flows, so mobile-captured data is available alongside web data in the normalized API.
