POI details and categories

Request POI details

To fetch details on a certain POI, use the Search.requestPOIDetails(options:completion:) API. It takes a POIDetailsOptions struct as input. The only required parameter is an identifier for the POI, which can be obtained in the SearchResultID of a SearchResult .

Only results of the POI type SearchResult are supported by the POI details request API.

You can request POI details in different languages. See the list of supported languages .

Specify the desired response language when creating POIDetailsOptions using a POIDetailsOptions.locale parameter.

If no language is specified, categories are returned in English.

onlineSearch.search(options: options) { [weak self] result in

    switch result {

    case let .success(poiSearchResponse):
11
        guard let result = poiSearchResponse.results.first,
12
              let resultID = result.searchResultID.id,
13
              let poiID = try? POIID(id: resultID, source: result.searchResultID.source) else {
14
            return
15
        }
16

17
        let poiDetailsOptions = POIDetailsOptions(
18
            poiID: poiID,
19
            locale: Locale(identifier: "en_GB")
20
        )

22
        self?.onlineSearch.requestPOIDetails(options: poiDetailsOptions) { result in
23
            switch result {
24
            case let .success(poiDetailsResponse):
25
                // handle success
26
                break
27
            case let .failure(error):
28
                // handle error
29
                break
30
            }
31
        }

33
    case let .failure(error):
34
        // handle error

onlineSearch.requestPOICategories(options: options) { result in
3
    switch result {
4
    case let .success(poiCategoriesResponse):
