Custom SweepBright integration
Appfront builds custom SweepBright integrations that automatically move your listings from the property CRM to your own website and portals. Through the SweepBright Website API and webhooks, we synchronise listings, descriptions and media in real time: as soon as you publish a property in SweepBright, it appears on your site. You manage your portfolio in one place and avoid duplicate entry and outdated information.
What is a SweepBright integration?
SweepBright is a mobile-first property CRM for estate agents, founded in Brussels. Agents manage their properties, contacts and listings there, often on the go from their phones. An integration pushes that portfolio out automatically: to your own website, to property portals or to an internal system, without you having to enter properties twice.
Technically, such an integration works on the basis of events. As soon as you publish, change or remove a property in SweepBright, the Website API sends a webhook (estate-added, estate-updated or estate-deleted) to your integration. It then fetches the current property data, including multilingual descriptions, location with coordinates, price information and media, and places it on your channel. For new-build projects, the individual units within a project are included too.
Appfront builds to the official SweepBright Website API documentation and the OWASP ASVS security standard. Because media URLs are temporary and the API may only be queried after a webhook, we configure the integration so that images and documents are stored locally, keeping your listings reliably on display even during peak traffic.
Real-time property sync
When you publish a property in SweepBright, it appears on your own website almost immediately. Price changes, status updates and removals come through via webhooks, so your online listings always match your CRM.
Webhook-driven
The integration responds to events rather than polling continuously. We validate every webhook message via its HMAC signature, then return a confirmation to SweepBright within the required time window.
Complete property data
Multilingual descriptions, location with coordinates, price and legal information, and, for projects, the underlying units. We present everything the Website API exposes neatly on your site or in your feed.
Our development process for SweepBright integrations
We follow a proven methodology that removes uncertainty early and delivers a stable integration. From an initial analysis of your listings, channels and SweepBright configuration through to go-live and ongoing management, every step is designed to produce an integration your office can understand and trust.
We map out which properties and projects you want to show, which channels they should go to (your own website, portals, internal systems), which languages you use, and how lead capture should flow back into SweepBright.
We design the webhook handling and OAuth 2.0 authentication, and set out a strategy for media storage and error handling within the Website API's time windows.
Implementation with automated tests, structured logging and monitoring. Along the way, you see working builds using real properties from your SweepBright environment.
Controlled go-live with data validation and a safety net for webhooks, followed by ongoing management and further development of the integration.
What a SweepBright integration delivers
Every SweepBright integration is tailored to your listings, your channels and the way you work. Below are the features we most often deliver for estate agents and property organisations that use SweepBright as their central property CRM.
SweepBright Website API
A robust integration with the official Website API (REST/JSON) using OAuth 2.0 authentication via Client ID and Client Secret. We retrieve listings, projects, locations and media cleanly and convert them into the format your website or system expects.
Webhook handling
Reliable processing of estate-added, estate-updated and estate-deleted events, with HMAC signature validation and timely acknowledgement within the required window. Failed processing is caught with retries and logging.
Listings sync to your website
Your SweepBright listings appear automatically on your own website, in the branding and structure you prefer. This includes filters by type, location and price, individual property detail pages, and proper handling of sold and let statuses.
Portal feeds
Alongside your own site, listings can also be sent to external property portals. We build feeds in the format each portal requires and keep them in sync with SweepBright, so you manage your portfolio in one place.
Lead capture back to the CRM
Contact forms and enquiries on your website are sent back to SweepBright via the Website API as contacts, linked to the right property. Leads land directly in the CRM, where your agents can follow them up.
Media and photo sync
Because the Website API returns temporary media URLs, we download and store images, floor plans and documents locally. Photos are optimised for the web, so your property pages load quickly and always show the right imagery.
Typical use cases in practice
A SweepBright integration looks different for every organisation. We see a number of recurring patterns, and for each we have a working setup that pays attention to webhooks, media storage and the presentation of properties and projects.
Estate agency
Residential estate agents who manage their listings in SweepBright and want to show them automatically on their own website. New listings, price changes and sold statuses flow through in real time via webhooks. See also our API integrations.
New-build and property developer
Developers publishing new-build projects with multiple units. We present the project as a whole as well as the individual units with their own price, status and availability, with a clear overview and detail view on your website.
Property management
Management organisations with a changing rental and letting portfolio that want to show their available properties online. The integration keeps availability and details in sync with SweepBright and sends enquiries back as leads.
Estate agency chain and franchise
Organisations with multiple branches that want to bring listings from a single SweepBright environment to a central website and to branch-specific pages. We build the feeds and filters so that each office displays its own listings within one consistent structure.
Technology we use
We build SweepBright integrations with the official Website API and webhooks, combined with the backend stack that suits you. The exact choice depends on your channels and your existing website, so that your own team or supplier can manage or further develop the integration.
Why choose Appfront for your SweepBright integration?
Appfront has extensive experience building API integrations for a wide range of organisations in the Netherlands. We always start with a thorough analysis of your existing systems and processes. An integration must not only work technically, but also add practical value to the way you work as an estate agent or property organisation.
For every integration, we write clear documentation and make sure your own team, or any future supplier, can understand and manage it. No black box, just transparent code and clear agreements on monitoring, alerting and maintenance.
You work with a dedicated point of contact who understands both the technical and the functional side. This keeps communication short, prevents misunderstandings and speeds up decisions when choices need to be made during development.

Security and privacy in SweepBright integrations
Property data almost always includes personal data, from owners, prospective buyers and interested parties. The SweepBright Website API works exclusively over HTTPS and authenticates via OAuth 2.0 with a Client ID and Client Secret, while every webhook message is signed with an HMAC signature that we validate. Appfront builds on this in line with the OWASP ASVS: credentials kept in secure vaults, permissions scoped per integration and strictly separated environments.
Because leads and property details fall under the GDPR, we document the data flows between SweepBright, your website and any portals, so your record of processing activities is complete and you can demonstrate compliance with the GDPR. We rotate the Client Secret periodically and store media responsibly within the applicable retention periods.
More on our security approach: information security policy and CVD policy.
- GDPR-compliant data processing and data minimisation
- Encryption in transit (TLS) on every API call
- OAuth 2.0 with scoped permissions and secret rotation
- HMAC validation of incoming webhooks
- Audit logs with traceable data flows
- Automatic retries and dead-letter queues
- Monitoring and alerting for anomalies
- Documentation for your record of processing activities
Frequently asked questions about SweepBright integrations
Answers to the questions we are asked most often about SweepBright integrations.
A SweepBright integration is a technical link between SweepBright, the mobile-first property CRM for estate agents, and another system, such as your own website, a portal feed or an internal system. Using the SweepBright Website API and webhooks, properties (estates) are synchronised in real time: as soon as you publish a property, your integration receives a webhook and retrieves the current details, descriptions and media. An integration can be simple (showing properties on your own website) or extensive (multilingual feeds, lead capture back into the CRM and synchronisation with external property portals).
A SweepBright integration suits estate agencies and property organisations that manage their listings in SweepBright and want to publish them automatically on their own website or on portals, without double entry. Because the Website API works through webhooks and may only be queried after a webhook event, an integration is particularly strong when you want real-time updates: a new listing, a price change or a sold status appears on your site almost immediately. For one-off exports without live sync, an integration is less necessary.
A straightforward integration, displaying listings from SweepBright on your own website via the Website API, with webhook handling and media storage, can go live within a few weeks. More complex scenarios, such as multilingual feeds, syncing to several portals, lead capture back into the CRM and custom presentation of developments and individual units, typically take longer. After an intake meeting, we give you a realistic estimate based on your situation.
We work with the official SweepBright Website API (REST/JSON) and webhooks, combined with the backend stack that suits you: Node.js, Python, PHP, .NET or Go. Authentication runs via OAuth 2.0 with a Client ID and Client Secret. We validate webhook events (estate-added, estate-updated, estate-deleted) using the HMAC signature in the X-Hook-Signature header. Because media URLs are temporary, we download and store images, floor plans and documents locally rather than requesting them live.
The cost depends on the complexity of the data flows, the number of channels to connect (your own website, portals, internal system), the desired presentation of listings and developments, and the amount of custom business logic. Multilingual support, lead capture back into the CRM and ongoing maintenance also affect the total investment. We always provide a clear quote after a no-obligation analysis of your situation.
Yes. The SweepBright Website API works exclusively over HTTPS and authenticates via OAuth 2.0 (Client ID and Client Secret), while webhooks are signed with an HMAC signature that we validate. Appfront builds in line with the OWASP ASVS: credentials in secure vaults, scoped permissions per integration and separate environments. Because properties often contain personal data of owners and prospects, we document the data flows so that your record of processing activities is complete and you can demonstrate GDPR compliance.
Yes. Appfront regularly takes over existing integrations, even those originally set up by another party. We review the webhook handling, the API integration, the media storage and the error handling, document the current setup and propose improvements. From that point on, we can handle adjustments, extensions and monitoring, including timely rotation of the Client Secret.
SweepBright is a mobile-first property CRM that suits estate agencies and property organisations that want to manage their listings on the go. Typical users include residential estate agents, new-build and property developers who publish units within projects, property managers, and estate agency chains or franchises with multiple branches.
