WoningMe Developer API

The Dutch rental API: query listings by city and radius, get webhooks on new matches

Listings from hundreds of rental agencies across the Netherlands, unified into one API, covering both social housing (housing-association listings) and private rentals. Save a search once. Then pull matching listings on demand, or let us push an HMAC-signed webhook to your server the moment a new one appears.

Search-scoped, not open-ended

Define a saved search once, with a city and radius_km, and every request runs against it, returning only the listings that match your search preferences. Filter by housing segment too: social housing (housing-association listings), private rentals, or both.

Signed webhooks, one retry included

Set a webhook_url on a search and we POST new matches with an X-WoningMe-Signature header (HMAC-SHA256) you can verify. A failed delivery gets one automatic retry after ~30 seconds, then shows up in your delivery history.

One API key, generated in your dashboard

Generate a key in your dashboard and you're authenticated in seconds. Put it in the X-Api-Key header and start making requests. Regenerate any time and the old key stops working right away.

Frequently asked questions

Is there a public API for Dutch rental listings?

Yes. The WoningMe Developer API is a REST API that gives you programmatic access to rental listings from hundreds of rental agencies across the Netherlands, unified into a single API you can query by city and radius, with optional webhooks for new matches.

Does the API cover social housing (housing-association) listings?

Yes. A search filter can match private-sector (vrije sector) listings, housing-association / public-sector (sociale huur) listings, mid-market rent (middenhuur) listings, or any combination of the three.

Is the WoningMe Developer API free?

Yes, full API and webhook access is free for every developer account until September 15, 2026, no credit card required to sign up. After that date, continued access requires an active subscription.

How do I get notified when a new rental listing matches my search?

Set a webhook_url on a search filter and WoningMe sends an HMAC-signed HTTP POST to it the moment a new listing matches, instead of you having to poll the API on a schedule.

Which Dutch cities does the rental API cover?

Coverage is nationwide across the Netherlands. A search filter is scoped to a city and a radius in kilometers around it, so you query exactly the area you care about.
