Immoweb Listing Detail API Documentation

GET https://scrappa.co/api/immoweb/listing/{id}?id=21882350

Scrappa's GET /api/immoweb/listing endpoint returns the complete record for a single Immoweb listing.

What the detail record contains

Detail is a strict superset of the search projection, so this endpoint returns every field a search result has, plus roughly a hundred more. Beyond the basics you get the full Belgian construction-permit block (including flood zone classification, cadastral plan availability and first-refusal-right flags), energy certificate details including the Flemish renovation obligation, judicial-measure and flood-certificate flags, and VAT and cadastral-income flags on sale transactions.

Agency data comes inline with the listing, including the Belgian IPI registration number. Both the top-level modification timestamp and the publication-level timestamp are returned unreconciled, because they describe different events.

Contact details are removed

Business contact details present in the upstream record — agency email addresses and telephone numbers — are stripped before the response is returned. They are not part of this endpoint's data contract.

Language

Pass language as nl, fr or en to choose the address and title language. Bare two-letter codes only. Immoweb publishes human Dutch and French titles alongside a machine-generated default, so English responses also carry alternativeTitles in Dutch and French.
