MarketSharp API
MarketSharp runs a REST API at restapi.marketsharpm.com with an OpenAPI spec referenced by third party trackers. Keys are generated in the paid admin app, sometimes only by request to MarketSharp, and auth stacks Company ID, user key, and secret key credentials. Public developer docs do not exist.
Frequently asked questions
MarketSharp scores D+ on the API Report Card. MarketSharp runs a REST API at restapi.marketsharpm.com with an OpenAPI spec referenced by third party trackers. Keys are generated in the paid admin app, sometimes only by request to MarketSharp, and auth stacks Company ID, user key, and secret key credentials. Public developer docs do not exist.
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.
MarketSharp is a cloud-based CRM and business management platform purpose-built for home improvement, remodeling, and exterior contractors.
Construction, specifically residential home improvement and remodeling contractors. In-home sales reps and canvassers log leads from web forms, call tracking, and direct mail; appointment setters book in-home consultations; sales reps run estimates and produce contracts on a tablet; production managers schedule installs and track jobs from sold to completion; office staff handle invoicing, payments via PaySimple, and QuickBooks sync.
Medium-high within home improvement and remodeling.
MarketSharp holds the operational core of a home improvement contractor's business: every inbound lead with its source (Angi, Modernize, QuinStreet, CraftJack, Networx, web form, call tracking, direct mail), homeowner contact and address, appointment history, in-home sales notes and presentations, signed contracts and proposals, product configurations, job/project status from sold through install, invoices and PaySimple payment records, QuickBooks-synced financials, referral and review pipelines (Listen360, GuildQuality, Testimonial Tree), and longitudinal lead-source ROI history.
Legacy. MarketSharp launched in 1986, making it nearly 40 years old and one of the original CRMs for the home improvement trade.
No publicly discoverable developer portal on marketsharp.com, API key generation and docs are gated behind a paid admin account, with no self-serve developer onboarding. API documentation is sparse and difficult to find, third-party API trackers note authentication details are not publicly disclosed. Full sourced list under Sources below.
Common alternatives include AccuLynx, JobNimbus, Builder Prime, Projul, Followup CRM, Leap. 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 MarketSharp API and MCP server so AI agents and internal tools can read and write MarketSharp data. See the MarketSharp integration docs at supergood.ai/docs/marketsharp-api.
