LMN API
No public REST API or developer portal; LMN's docs state Zapier is the only API integration available. Zapier access is gated to Professional ($648/mo) and Enterprise plans, and triggers only see records touched in the last 24 hours. Beyond that: QuickBooks sync, Stripe payments, and manual CSV.
Frequently asked questions
LMN scores F on the API Report Card. No public REST API or developer portal; LMN's docs state Zapier is the only API integration available. Zapier access is gated to Professional ($648/mo) and Enterprise plans, and triggers only see records touched in the last 24 hours. Beyond that: QuickBooks sync, Stripe payments, and manual CSV.
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.
LMN (Landscape Management Network) is an all-in-one business management SaaS purpose-built for landscape contractors.
Field Service Management, specifically SMB and lower-mid-market landscape contractors. Named target segments include residential and commercial landscape maintenance, design-build, snow & ice management, irrigation, and lawn care. Field crews use the LMN Crew mobile app to clock in/out, switch between jobs, log production quantities (e.g., square feet mowed, yards of mulch installed), capture photos and notes, and operate offline when out of coverage.
Medium-to-high within its niche.
LMN holds the operational and financial system of record for the landscape contractors that run on it: complete CRM with leads, customers, and property records; budget-based estimates with labor/material/equipment/overhead detail; the scheduling calendar and crew assignments; mobile-captured time, production quantities, photos, and offline-synced field data; real-time job-cost and estimate-vs-actual data; invoices and accounts receivable; LMN Pay (Stripe) ACH and credit card payment history; the customer portal and signed proposals; and the QuickBooks-synced general ledger for revenue, customers, and payments.
Mature. LMN has been on the market since 2009 and merged with SingleOps and Greenius under the new Granum parent brand in November 2024.
Zapier is the only API integration available; there is no public REST API, no developer portal, and no OAuth, leaving customers locked into LMN's pre-built connectors. API/Zapier access is gated to Professional ($648/mo) and Enterprise tiers; Starter ($297/mo) customers cannot programmatically integrate at all. Full sourced list under Sources below.
Common alternatives include Aspire (ServiceTitan), Jobber, Service Autopilot (Xplor), Housecall Pro, Real Green Systems (WorkWave), SingleOps (Granum sibling). 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 LMN API and MCP server so AI agents and internal tools can read and write LMN data. See the LMN integration docs at supergood.ai/docs/lmn-api.
