  • The build-it-yourself problem

Marketplace syndication is a multi-year engineering project

Every platform that builds listing distribution in-house runs into the same four walls. They have nothing to do with your product and everything to do with the marketplaces themselves.

2 to 4 years

To build full coverage

Each marketplace is its own integration: separate schemas, auth flows, media specs, and approval processes. Multiply by 48.

Commercial agreements

Many networks require a negotiated partnership before you can publish a single listing. Business development cycles stack up fast.

Maintenance never ends

Feeds break silently every time a marketplace changes its spec. Data mapping becomes a permanent line on your engineering roadmap.

US and Canada differ

Canadian classifieds and MLS boards do not overlap with US consumer platforms. Cross-border coverage doubles the work.

How it works

Push listings once. We handle everything downstream.

A REST API with webhooks, built for engineering teams. 

You keep your data model. We translate it to every marketplace on the network..

Integrate once

Connect through a documented REST API with a sandbox environment. Send listings in your schema with a single POST /listings.

We normalize and validate

Who it’s for

Built for teams that own their own stack

Ship syndication as a native feature

PMS vendors, leasing CRMs, and rental products that want distribution inside their platform without building the plumbing.

Distribute from your in-house system

Property managers and asset owners running internal leasing stacks who need marketplace reach without replacing anything.

Reliable inventory, in or out

Listing platforms that need a clean, validated feed of rental supply, or want to extend their inventory’s reach across the network.

Network coverage

True North American coverage, not US-only with extras

Most syndication feeds stop at US consumer platforms. The Leasey network covers consumer marketplaces, classifieds, and MLS boards in both countries.

FAQ

Questions your team will ask

Most teams reach their first live listing within a few weeks. The API is REST with webhook callbacks, ships with a sandbox environment, and your Leasey technical contact works with your engineers through go-live.

No. Leasey holds the commercial relationships with every network we distribute to, including MLS boards and association partners. One agreement with Leasey covers the full network.

We update the mapping on our side. Your integration contract with the Leasey API stays stable, so marketplace changes never land on your engineering backlog.

Yes. Webhooks deliver per-marketplace publish confirmations, errors, listing updates, and inbound leads in real time, so your platform stays the system of record.

Yes. For PropTech partners, syndication runs under your brand inside your product. Your customers interact with your platform; Leasey is the infrastructure underneath.

Pricing combines a platform fee with usage-based volume tiers, sized to your listing volume and coverage needs. We will walk through the model in the demo.
