Knowify API
Knowify is construction management software that helps trade and specialty contractors run estimating, project execution, service work, job costing, and AIA billing on one platform, with the strongest QuickBooks sync in construction. An unofficial API lets you programmatically pull contract jobs, service jobs, clients, tasks, invoices, vendors, and products—and push updates like new jobs, clients, vendors, and task changes back into Knowify.
What is Knowify?
Knowify is construction management software built for trade and specialty contractors—electrical, plumbing, HVAC, painting, remodeling, concrete, and excavation—covering the full workflow from estimating and proposals through project execution, service work, job costing, and invoicing on a single platform. Contractors use Knowify to build estimates and contracts, schedule crews, track change orders and daily logs, run AIA progress billing, cost jobs in real time, and sync financials to QuickBooks—marketed as the strongest QuickBooks sync in construction.
Core product areas include:
- Project execution (estimating, proposals, contracts, scheduling, change orders, RFIs & submittals, document management, daily logs)
- Service work (scheduling & dispatch, service invoicing & payments, client communication, field operations & asset management)
- Financial management (AIA billing, budgeting, invoicing, payment processing, job costing, reporting)
- Subcontractor and inventory management, client portal, CRM, fleet tracking, and custom workflows
- Integrations with QuickBooks Online, QuickBooks Desktop, Intuit Enterprise Suite, QuickBooks Payroll/Payments/Time, CompanyCam, Lumber, eBacon, Billd, and AIA Contract Documents
Common data entities:
- Contract Jobs, Service Jobs, Estimates, Proposals, Change Orders
- Clients, Vendors, Subcontractors, Products
- Tasks, Schedules, Daily Logs, Time Entries
- Invoices, Bills, Payments, Purchases
- Job Costs, Budgets, AIA Pay Applications
The Knowify Integration Challenge
Contractors run estimating, field operations, and billing through Knowify every day, but turning those workflows into reliable API-driven automation is non-trivial:
- Tier-gated API access: Programmatic access via the API key is limited to Growth and Enterprise subscriptions and generated in the Admin Customize tab, so lower tiers have no developer surface
- Zapier-centric automation: Public connectivity is framed around Zapier triggers and actions rather than a documented open REST API, limiting bulk reads, pagination, and complex queries
- Mobile-first field data: Daily logs, time entries, dispatch, and photos originate in the mobile app and field tools, which are harder to reach headlessly than back-office records
- QuickBooks-coupled financials: Invoices, bills, and payments are tightly synced to QuickBooks, so integrations must respect Knowify's sync state to avoid duplicating or breaking accounting records
- Construction-specific objects: Change orders, AIA pay applications, and job costing have domain-specific lifecycles and retention/billing rules that generic connectors mishandle
- Session and credential handling: Headless access to the full Knowify surface beyond Zapier requires authenticated session management and careful rate control
How Supergood Creates Knowify APIs
Supergood reverse-engineers authenticated browser flows and Knowify's API-key and Zapier surfaces to deliver a resilient, full-coverage API layer for your Knowify account—across project execution, service work, and financials.
- Handles login and session management securely, including credential rotation and refresh
- Reaches data and actions beyond the Zapier trigger/action set, including bulk reads and field-originated records
- Normalizes responses across contract jobs, service jobs, clients, invoices, vendors, and products so you integrate once against consistent objects
- Respects Knowify's QuickBooks sync state and construction-specific billing rules to keep financial records clean

Frequently asked questions
Knowify's native API key is available on Growth and Enterprise tiers and generated in the Admin Customize tab. Supergood works with your existing entitlements and authenticated sessions, and can reach data beyond the native key and Zapier surface.
Yes. Knowify's public connectivity is framed around Zapier triggers and actions for jobs, clients, tasks, invoices, vendors, and products. Supergood delivers a full API layer including bulk reads, pagination, and field-originated records that Zapier alone does not expose.
Supergood respects Knowify's QuickBooks sync state for invoices, bills, and payments, so integrations read and write financial records without creating duplicates or breaking accounting reconciliation.
Yes. Field-originated records such as daily logs, time entries, dispatch assignments, and photos are exposed through the same normalized API surface alongside back-office jobs and billing.
Yes. Change orders, AIA pay applications, job costs, and budgets are profiled with their construction-specific lifecycles and billing rules rather than forced into a generic schema.
