The problem

Stop building portal integrations.

Every property portal has its own API, XML format, authentication, validation rules and operational quirks. Your CRM speaks Listflow. Listflow speaks every portal.

One schema

Normalize listing data once.

One API

Create, update and delete everywhere.

One webhook model

Receive publishing status consistently.

One integration

Listflow maintains portal-specific changes.

One integrationOne API → N portals

Declarative sync

Tell us where the listing should be

Developers do not manage individual CREATE/UPDATE/DELETE calls per portal. Declare the desired distribution — Listflow converges actual portal state to match.

Declarative syncDesired → actual

01Desired

Declare the distribution once. No per-portal create, update, or delete calls.

Universal schema

One property model

Instead of translating your CRM model separately for every portal, map your data to Listflow once. Listflow translates the canonical listing into each portal schema.

Universal schemaMap once → translate many

01Listflow Listing

One canonical property model. Map your CRM fields here — not to every portal.

{
  "id": "property_123",
  "operation": "sale",
  "type": "apartment",
  "price": 450000,
  "currency": "EUR",
  "bedrooms": 3,
  "bathrooms": 2,
  "area_m2": 98,

Portal intelligence

We handle the portal rules

Portal quirks stay behind a predictable interface. Your app sees structured API responses — not opaque feed failures.

Portal intelligenceQuirks → structured API

01Rules we absorb

Validation, auth, feeds, retries, and portal-specific quirks — handled once behind Listflow.

Required fields
Type mappings
Image rules
Location maps
Authentication
Rate limits
XML feeds
REST APIs
Retries
Portal errors
Remote IDs
Pub status

02What you get

Predictable

Portal failures become structured API responses. Validate early and keep retries deterministic.

error.jsonjson

{
  "code": "MISSING_REQUIRED_FIELD",
  "portal": "imovirtual",
  "field": "energy_certificate",
  "retryable": false
}

Missing fields, portal codes, and retryability — all explicit.

Reliability

Listings eventually arrive where they should

Listflow treats distribution as a convergence problem: desired state in, reconciled portal state out — with isolation so one portal never blocks another.

ReliabilityDesired → reconciled

02Guarantees

Isolated

One portal failing never blocks another. Retries, idempotency, and reconciliation keep state converging.

API

A small API for a complicated problem

The public surface stays small even as portal complexity grows. Integrate once; extend coverage without changing your application contract.

02Your contract

Stable

Integrate once. Portal complexity grows behind the same application contract.

A handful of endpoints cover the hard parts.
Stable contract
Add portals without rewriting your integration.
Composable
Upsert, distribute, validate — same listing id.

SDK exampleUpsert → distribute

01publish.ts

One upsert. One distribution call. Listflow handles the portals.

publish.tsts

import { Listflow } from "@listflow/sdk"

const listflow = new Listflow({
  apiKey: process.env.LISTFLOW_API_KEY
})

await listflow.listings.upsert({
  id: "property_123",
  operation: "sale",
  type: "apartment",
  price: 450000,
  currency: "EUR",
  bedrooms: 3,
  location: {
    city: "Lisbon",
    country: "PT"
  }
})

await listflow.distribution.set("property_123", {
  idealista: "published",
  imovirtual: "published",
  greenacres: "published"
})

Use cases

Built for the systems that already own inventory

Listflow sits under CRMs, marketplaces, proptech products and agents — not beside them as another agency tool.

Use casesYour system → Listflow

01Who it is for

CRM platforms
Add portal export without maintaining dozens of integrations.
Property marketplaces
Distribute inventory to downstream listing channels.
Proptech products
Make listing distribution a feature instead of an integration project.
AI agents
Publish property inventory through deterministic tools and schemas.

02How it fits

Infrastructure

Listflow is the distribution layer under products that already own inventory — not another tool beside them.

Sits under your stack
Infrastructure for systems that already own inventory.
Not an agency tool
Built for product and platform teams, not side workflows.
One integration surface
Ship portal coverage as a product feature, not a project.

Portals

One integration, growing portal coverage

The pain

One listing. Many formats.

Every portal wants its own API, schema, auth and quirks.
