Custom Realworks integration development
Appfront builds custom Realworks integrations that automatically sync your property listings to your own estate agency website and write leads back to your CRM. Through the official Realworks API and webhooks, we connect listings, relations, match profiles and media, so your site always shows current stock and no lead gets lost. You manage your portfolio in one place and publish consistently everywhere.
What is a Realworks integration?
Realworks is a widely used estate agency software and real estate CRM platform in the Netherlands, closely linked to the NVM. Estate agents manage their property listings, relations and matching profiles in it, and publish their listings to Funda and other property platforms. For many offices, the Realworks CRM is therefore the central system where all listing and relationship data comes together.
In practice, a custom integration means: reading property listings from Realworks programmatically and displaying them on your own estate agency website, writing leads from forms back to your CRM, linking search profiles so that buyers and renters automatically see the right listings, and keeping media such as photos and floor plans in sync. Via webhook sync, your website stays up to date with every change, without any double entry.
Appfront builds in line with the official Realworks developer documentation and the OWASP ASVS security standard. We align listing synchronisation, lead write-back and error handling with how you actually work, so the integration grows with your office and remains reliable even at high listing volumes.
Listings always up to date
Property listings from Realworks appear automatically on your own website. Status changes, price updates and new listings are passed on immediately, so your site never shows outdated information.
Leads back into the CRM
We write enquiries submitted through contact and viewing forms directly back to Realworks as a relation or search request. Your agents work from a single source, without typing leads over by hand.
Matching that works
Matching profiles connects the right listing to the right buyer or renter. New properties are matched against existing saved searches, so prospects are notified quickly and with relevant options.
Our development process for Realworks integrations
We work to a proven methodology that removes uncertainty early and delivers a stable integration. From an initial analysis of your listings, relationships and website through to go-live and ongoing management, every step is aimed at an integration that your office can understand and trust.
We map out which listings and relationships from Realworks need to be connected, which leads and saved searches need to flow back to your CRM, and whether matching, media or marketing automation are involved.
We design the integration architecture, request the API key and developer ID, choose the right sync strategy and define an error-handling strategy.
Implementation with automated tests, structured logging and monitoring. You see working builds along the way.
Controlled go-live with data validation and a safety net, followed by ongoing management and further development.
What a Realworks integration delivers in practice
Every Realworks integration is tailored to your listings, relationships and adjacent systems. Below are the features we most often deliver for estate agents and property businesses that use Realworks as their central CRM.
Property listings to your website
Listings from Realworks are read and displayed on your own estate agency website, including features, price, status and location. We push changes through webhook sync so that the listings on your site always match the CRM.
Contact & lead sync
Leads from contact, viewing and valuation forms are written back to Realworks as a contact or search request. Statuses and follow-up stay in sync, so your agents work from one central source.
Linking matching profiles
Search profiles from Realworks are linked to new and existing listings. When a property matches a saved search, the match can automatically trigger a notification or property alert to the right prospect.
Media & photos
We bring across photos, floor plans and brochures from Realworks and display them optimised on your website. Image sizes, order and captions stay in sync with the listing in the CRM.
Marketing automation
New and updated listings trigger property alerts, newsletters or campaigns in your marketing tool. This way, searchers automatically receive suitable listings, powered by current data from Realworks.
BI dashboards
We make listing, lead and time-on-market data available to BI tools for clear reporting. You can see trends by branch, agent or property type, for example through our Power BI integration.
Typical use cases in practice
A Realworks integration looks very different from one organisation to another. We see a number of recurring patterns, and for each we have a working setup that pays close attention to listing synchronisation, lead write-back and the right matching and media logic.
Estate agency firms
NVM and independent estate agents who manage their property listings centrally in Realworks and want to show them on their own website. Listings, prices and statuses stay in sync, and leads from forms flow back into the CRM. See also our API integrations.
Property management
Property managers and letting organisations with larger portfolios who want to structure their listings, relationships and changes. We connect Realworks to portals and internal systems and keep properties and contact details reliably in sync.
Proptech builders
Builders of property portals, property search apps and valuation or mortgage tools that need listings and matching profiles from Realworks. We deliver a robust, documented integration that your product can build on with confidence.
Web agencies for estate agents
Agencies that build estate agent websites and want a reliable Realworks integration underneath their sites. We handle listing sync, lead write-back and media integration, with clear documentation so you stay in control of management.
Technology we use
We build Realworks integrations using the official Realworks API and webhook sync, combined with the backend stack that suits you. The precise choice depends on your website, portals and marketing tools, so that your own team can manage or further develop the implementation.
If you want to publish listings from your own system via the NVM exchange system, see our page on a TIARA integration.

Security and privacy in Realworks integrations
A Realworks integration always handles relationship and personal data: contact details of buyers and sellers, search requests and leads from forms. Appfront builds to the Realworks security best practices and the OWASP ASVS. That means, among other things: API keys and tokens held in secure vaults, webhook signature validation, scoped permissions per integration and regular audits of the listing and lead flows.
We document the data flows between Realworks, your website and your marketing tools, and apply data minimisation so that only the necessary fields are exchanged. This keeps your record of processing activities complete and helps you demonstrate compliance with the GDPR. Audit logs make every data flow traceable.
More on our security approach: information security policy and CVD policy.
- GDPR-compliant processing of relationship and personal data
- Data minimisation for listing and lead fields
- Encryption in transit (TLS 1.2+) and at rest
- Role-based access and least-privilege principles
- 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 Realworks integrations
Answers to the questions we are asked most often about Realworks integrations.
A Realworks integration is a technical link between the Realworks CRM and another system, such as your own estate agent website, a property search portal, a lead form or a marketing tool. Through the Realworks API, property listings are read from the CRM and published on your site, leads and search requests are written back to the CRM, and match profiles and media such as photos and floor plans stay in sync. An integration can be simple (showing listings on your website) or extensive (lead sync, matching, marketing automation and BI dashboards).
Realworks suits NVM-affiliated estate agents and property firms in the Netherlands that manage their listings, relations and match profiles centrally and publish them to Funda and other property platforms. It aligns closely with the NVM and Funda standards for property listings. If you operate internationally or in a different property segment, another CRM or platform may be a better fit; we will work with you to determine which approach best suits the way you work.
A simple integration, such as showing Realworks property listings on your own website, is usually live faster than an extensive one. Scenarios involving lead sync back to the CRM, match profiles, media synchronisation, marketing automation and BI dashboards take longer. After an introductory meeting, we map out the scope and give you a realistic estimate.
We work with the official Realworks API and webhook sync, combined with the backend stack that suits you: Node.js, Python or PHP. Authentication runs via an API key and tokens, linked to your branch number and developer ID. We call the endpoints for objects, relations and media, and take the Funda and NVM standards for property listings into account so that publication stays consistent.
The cost is determined by the complexity of the data flows, the number of systems to connect, the required synchronisation frequency and the amount of custom work in the business logic, such as matching, media processing or marketing automation. Ongoing management, monitoring and support also affect the total investment. We always provide a clear quote following a no-obligation analysis of your situation.
Yes. A Realworks integration processes relationship and personal data of buyers and sellers, so we build to the OWASP ASVS standard: API keys and tokens in secure vaults, webhook signature validation, scoped permissions per integration and strict data minimisation. We document the data flows between Realworks, your website and your marketing tools so that your record of processing activities stays complete and you can demonstrate GDPR compliance.
Yes. Appfront regularly takes over existing Realworks integrations, including those originally set up by another party or web agency. We review the API integration, listing synchronisation, lead write-back and error handling, document the current setup and propose improvements. From that point on, we handle changes, extensions and monitoring, including timely rotation of API keys and tokens.
Realworks suits estate agencies, property managers, proptech builders and web agencies that build estate agent websites. Typical use cases: synchronising property listings to your own site, writing leads from forms back to the CRM, linking match profiles to buyers, displaying media and floor plans, and publishing listings via the Funda and NVM standards. For parties outside NVM estate agency or in other property segments, we will look at whether another platform is a better fit.
