Request

  • A JSON request object has to be send in the body of the post request which provides all available information of the real estate that should be valuated. It follows a list of all possible keys in the JSON request object.
  • All keys marked in bold are mandatory. Depending on the type of the real estate (key realEstateType) the key floor has to be set if it is an APARTMENT, otherwise (in case of a house) the key siteArea has to be set. This keys are marked with a i.
  • Furthermore, either a coordinate or an address has to be provided. In both cases all fields within that object have to be set and will not be accepted if any of them is empty or has a wrong format. That means that if you provide a address, you also have to provide the street, houseNo, zip and city.
  • Please note that the keywords are case sensitive, e.g. END_TERRACE_HOUSE will be recognized, but end_terrace_house not.

If status 400 shown (BAD REQUEST) then it is furthermore possible that the geocoding was not possible for the given address or coordinate and therefore no or no unique neighbourhoodId could be determined. In this case the HTTP status code is 400 (Bad Request) with a detailed error message in the body. If you don't want to receive a 400 there is the possibility to get a 204 (No Content) if the flag showGeocodingErrors is set to false.
