Hussteer API

Your data. Your tools. Connected.

Connect Hussteer to your applications, automate your data exchanges and build your own experiences around your property business.

A simple API

No need to reinvent your stack.

HTTP, JSON and an OpenAPI specification. Hussteer builds on the technologies your teams already use.

REST

Available

Simple by design.

Standard HTTP requests, structured JSON responses and explicit error codes.

OpenAPI 3.1

Available

The specification is published.

The API contract is served at /openapi.json and /openapi.yaml, ready for your tooling.

Publishing

Available

The first domain opened.

Start a distribution, follow its status, read its history, retry a failing channel.

Access keys

Coming

Controlled access.

Key-based authentication, tied to an agency and revocable, is still to be delivered. Calls today use a Hussteer session.

The flow

Hussteer becomes the crossing point.

Your data can move between Hussteer, your website, your internal tools and the services connected to your agency.

The Publishing domain is open today. Other resources will be exposed step by step.

What you can build

One API. Many possibilities.

Connect your own services without rebuilding your business around a new tool.

Follow your listings

Available

Keep an eye on distribution.

Use the statuses — queued, running, success, error — to track how your listings are doing.

Retry a channel

Available

Fix without going back to the screen.

Resume a failed distribution from your own tools, channel by channel or all at once.

Check before sending

Available

Validate the record before publishing.

Check that a property meets the publishing conditions and get the list of what is missing.

Build automations

Available

Trigger actions without manual steps.

Chain publishing calls from your own workflows.

Connect your website

Coming

Your portfolio feeds your shop window.

Read access to properties and mandates is among the domains still to open.

Use your data

Coming

Turn activity into insight.

Exporting to your dashboards currently goes through the CSV files in the settings.

A key will be tied to a single agency and open only its resources.

Authentication

One key. One agency. One scope.

Calls are currently authenticated with a Hussteer session: the API sees exactly what the signed-in user sees, within their agency's scope.

Key-based authentication — creating, using and revoking from the settings — is the next step.

Create: generate a key from the agency settings.
Use: authenticate the connected service's calls.
Revoke: cut off an access that is no longer needed.
Webhooks

Capability to come: these events exist internally but are not delivered yet.

Payload

{ "event": "mandate.published", "mandateId": "212", "at": "2026-08-27T09:12:04Z"}
Webhooks

Stop asking. Hussteer tells you.

Webhooks will let your applications react when something happens in Hussteer, instead of polling the API.

The Mandates domain events already exist internally.
Delivering them to your services is still to be built.
In the meantime, the status endpoint reports where a distribution stands.

Documentation should follow the product.

Hussteer's technical reference is built on OpenAPI 3.1, so the documentation stays aligned with what the API actually accepts and returns.

API reference

Endpoints, parameters, responses and errors.

OpenAPI

A description your tooling can read directly, served at /openapi.json.

Examples

Ready-to-copy calls in cURL, JavaScript and Python.

The full developer reference will open progressively to partners and integrators holding an API access.

Security

Connected does not mean open to everything.

API access follows the same partitioning and control principles as the rest of the platform.

Limited access

A call only sees its own agency's resources: the rule is enforced by the database, not by the API.

Revocation

A session cuts off immediately, and future keys will follow the same principle.

Traceability

Sensitive actions are logged and available from the agency settings.

Trust, security and transparency

Hussteer is a SaaS platform built for real-estate professionals. We are committed to protecting your data, keeping our services transparent and complying with applicable regulations.

Data protection

The data you import, create or store in Hussteer remains yours. It is never resold to third parties and is processed in accordance with the General Data Protection Regulation (GDPR).

Artificial intelligence

Hussteer's artificial-intelligence features are designed to assist professionals in their daily work. Automatically generated content — including property descriptions, summaries, replies or suggestions — must be checked before publication. Users remain responsible for the information they publish.

Voice publishing

Voice commands are analysed in order to create or complete property records. Voice recognition may misinterpret input. Human validation is always recommended before publishing.

Listing distribution

Listings can be sent to various property portals and partner services. Availability of integrations, publication times and certain features depend on the APIs and terms of use of each partner.

Electronic signature

Where an electronic signature is used, it is provided by a specialist provider. The signature process, archiving and retention of evidence are the provider's responsibility, in line with applicable regulations.

Service availability

We do everything we can to provide a reliable, high-performing platform. Temporary interruptions may nonetheless occur during maintenance, or as a result of events beyond our control.

Security

Traffic between your browser and Hussteer is encrypted. We apply technical and organisational measures designed to protect your data against unauthorised access, loss and alteration.

Third-party integrations

Some features rely on third-party services such as property portals, electronic-signature providers, mapping services, payment solutions and artificial-intelligence models. Hussteer cannot be held responsible for interruptions, changes or limitations originating from those services.

Platform evolution

Hussteer evolves continuously. Features, integrations, pricing and terms of use may change in order to improve the service or to meet regulatory developments.

Limitation of liability

Hussteer provides support tools for real-estate professionals. Users remain solely responsible for the information they publish, for valuations, listings, generated documents, mandates and collected signatures, and for compliance with their legal and professional obligations.
