One Click Contractor API

One Click Contractor is a home improvement sales platform that powers digital estimating, branded proposals, instant multi-lender financing, e-signature, and payment collection for remodeling and exterior contractors. An unofficial API lets you programmatically pull estimates, proposals, jobs, financing applications, signed contracts, and payment records—and push new estimates, line items, and status updates back into One Click Contractor.

What is One Click Contractor?

One Click Contractor is a home improvement sales and estimating platform for remodeling and exterior contractors—roofing, siding, windows, gutters, bathrooms, and kitchens. Sales reps use it to capture measurements, build estimates in minutes, present branded proposals with live price adjustments, offer instant financing through multiple lenders, and capture e-signatures and payments in a single in-home appointment. The platform reports more than $14 billion in project estimates processed and integrates with 50+ measurement, CRM, presentation, financing, and payment tools.

Core product areas include:

  • One Click Estimating (digital estimates, templated line items, locked-in pricing, branded proposals)
  • 1LOOK Financing (single soft-pull application matched across multiple lenders, real-time approval and funding)
  • Measurement integrations (EagleView, Hover, and in-app measurement tools)
  • E-signature and payment collection (contract sign-off and deposit capture in the appointment)
  • CRM, accounting, and presentation integrations (Salesforce, FeneVision, InGage, and other connected systems)

Common data entities:

  • Estimates, Line Items, Pricing Templates, Proposals
  • Jobs, Appointments, Customers, Contacts
  • Financing Applications, Lender Offers, Approvals
  • Measurements, Documents, Signed Contracts, Payments
  • Users, Teams, Branches

The One Click Contractor Integration Challenge

Contractors close deals in One Click Contractor every day, but turning its in-app, appointment-driven workflows into API-driven automation is non-trivial:

  • No public API: One Click Contractor does not publish a developer API or documentation, so there is no official surface to build against
  • Integration-only access: Native connections (Salesforce, EagleView, Hover) are configured in-app via OAuth consumer key/secret, not exposed as general-purpose endpoints
  • Field-and-mobile data: Estimates, signatures, and payments are captured live in the home, so data lives behind authenticated rep sessions rather than a batch export
  • Financing partner gates: 1LOOK financing applications flow through multiple third-party lenders, each with its own approval state and sensitive data handling
  • Template and pricing variability: Line items, locked pricing, and proposal templates are configured per contractor, so generic integrations break across accounts
  • Zapier-only stopgaps: Teams often fall back to Zapier for Salesforce sync, which is brittle, partial, and hard to scale across branches

Frequently asked questions

No. One Click Contractor does not publish a developer API or documentation. Supergood works against your authenticated account sessions and in-app integration flows to provide a stable API layer without requiring an official public API.
