Frequently asked questions
One Click Contractor scores F on the API Report Card. No public REST API or developer portal. Programmatic integration is outbound webhooks configured in the admin UI plus an invitation-only Zapier connector whose sole inbound action is Create Job. Webhook auth tops out at Basic; there is no HMAC signing or OAuth.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
One Click Contractor (OCC) is a sales enablement and digital estimating platform purpose-built for residential home improvement contractors.
Construction, specifically residential home improvement contractors selling replacement windows, doors, siding, roofing, gutters, bath/shower remodels, and kitchen remodels. In-home sales reps run the entire kitchen-table close on a tablet: pull aerial/remote measurements from EagleView or Hover, build a guided estimate with locked product catalog and pricing rules, present a branded proposal with visualizers (Renowork, Alside, Ply Gem, CertainTeed ColorView, GAF Virtual Home Remodeler, Sherwin-Williams ColorSnap), demo financing options via 1LOOK with on-the-spot multi-lender approval, collect e-signature on the contract, and capture deposit through One Click Payments.
Medium within home improvement.
OCC holds the high-value end of a home improvement contractor's sales funnel: every estimate built in the platform with full line-item product configuration and pricing, every branded proposal sent to a homeowner, every signed contract and e-signature record, every deposit and progress payment processed through One Click Payments, every consumer financing application and approval routed through the 1LOOK multi-lender platform (including soft-pull credit data and lender decisioning history), all in-home appointment notes and presentation history, photos captured at the kitchen table, and a longitudinal record of close rates, average ticket, and rep performance.
Modern. Founded in 2017, OCC is one of the newer in-home sales platforms and is built cloud-native with iPad/tablet-first UX, e-signature, integrated payments, and a webhook event model.
No public REST API and no self-serve developer portal, programmatic integration is limited to outbound webhooks and an invitation-only Zapier connector. Zapier integration is gated behind a manual invitation rather than self-serve, slowing time-to-integrate for new customers. Full sourced list under Sources below.
Common alternatives include Leap, Ingage, Improveit 360, MarketSharp, AccuLynx, JobNimbus. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial One Click Contractor API and MCP server so AI agents and internal tools can read and write One Click Contractor data. See the One Click Contractor integration docs at supergood.ai/docs/one-click-contractor-api.
