LeafLink API
A documented REST API at developer.leaflink.com covers orders, products, inventory, and customers, versioned with dated headers. Keys are not self-serve: partners request them through LeafLink Support. There are no SDKs or first-class webhooks, and a legacy V2 API still runs alongside.
Frequently asked questions
LeafLink scores F on the API Report Card. A documented REST API at developer.leaflink.com covers orders, products, inventory, and customers, versioned with dated headers. Keys are not self-serve: partners request them through LeafLink Support. There are no SDKs or first-class webhooks, and a legacy V2 API still runs alongside.
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.
LeafLink is the dominant B2B wholesale marketplace for the licensed cannabis industry in North America, connecting brands, cultivators, manufacturers, distributors, and retailers on a single platform that bundles ordering, payments, logistics, advertising, insights, banking, and ERP/seed-to-sale integrations.
Vertical B2B SaaS / marketplace for state-licensed cannabis supply chain. Customers include licensed cultivators, processors/manufacturers, brands, distributors, and dispensary retailers across 30+ regulated US and Canadian markets. A cannabis brand uploads its product catalog, line sheets, and pricing tiers; sales reps build orders with retail buyers either through assisted/sales-rep workflows or self-serve menus; orders flow through LeafLink with automated compliance checks against state traceability (Metrc, BioTrack); buyers pay via LeafLink Pay (ACH, net terms, escrow) with Dama-powered banking rails; LeafLink Logistics arranges compliant freight and proof-of-delivery; inventory, orders, and invoices sync bidirectionally to the seller's ERP/seed-to-sale system (Distru, Flourish, Canix, LeafLogix, Sage Intacct, NetSuite, QuickBooks) via the LeafLink API or partner connectors; brands run targeted advertising and promotions to dispensary buyers; both sides consume LeafLink Insights for category-level pricing and demand benchmarking.
8/10 within cannabis wholesale; ~2-3/10 outside the vertical. LeafLink publicly cites 50%+ share of wholesale cannabis transactions, 5M+ wholesale transactions processed, $1B+ in payments processed, 12,000+ sellers and buyers, and 3,500+ brands.
Yes - LeafLink is the system of record (or a critical mirror) for the cannabis brand and distributor's wholesale book of business: full B2B product catalog and pricing tiers, line sheets, buyer accounts, sales-rep assignments, order and reorder history, line-item invoicing, ACH/net-terms payment data via LeafLink Pay, freight and proof-of-delivery records from LeafLink Logistics, inventory snapshots reconciled against Metrc/BioTrack traceability, advertising spend and impression data, and category/price benchmarking from LeafLink Insights.

API access is gated behind a Support Team request rather than self-serve developer signup, adding lead time for integrators. CORS is explicitly disallowed for all endpoints, forcing all integrations through a server intermediary and complicating browser-side tooling. Full sourced list under Sources below.
Common alternatives include Apex Trading, Leaf Trade, Kush Marketplace, Distru, Flourish Software, BLAZE Wholesale. 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.
