A 43-byte Base64 URL-safe encoded string used for the authentication of the client application. As a logged in user, you can generate it at https://developer.here.com/projects. API Keys never expire but you can invalidate your API Keys at any time. You cannot have more than two API Keys for one app at the same time.
You must include an
|app_id||Yes||A URL-safe encoded string obtained during the application registration. If you use the app ID/app code option as an authentication method, for further details see Acquiring Credentials.|
|app_code||Yes||A URL-safe encoded string obtained during the application registration. If you use the app ID/app code option as an authentication method, for further details see Acquiring Credentials.|
|layer_id||Yes|| Layer ID identifying the layers to be searched. Can also be a comma separated list of layers. Layer names are not case sensitive. The maximum length of a layer name and the permitted characters can be lookup up in the service via |
|geom||No||full or none. Specifies the geometry representation in the result. Default = full. |
Columns value for the geometry are available as defined variables.
When specified, only geometries where expression evaluates to true will be returned.
Example: filter=RATING > 3 && NAME != 'MyPlace23' && NAME.startsWith('Food')
Parameter value must be url encoded when using special characters.
This filter expression is applied after the spatial filtering, hence only to few geometries. Only for the
To avoid service overload, filter expressions must not exceed 100 characters of text and their execution on the result must not exceed 100 ms execution time.
|start_geometry_id||No|| To paginate huge responses, this parameter specifies the lowest geometry id to be returned. If geometry ids are not known, then retrieve the first page using zero, and to retrieve subsequent pages then request highest geometry of current page + 1 (it doesn't matter whether this geometry id actually exists or not). Use this parameter together with |
The maximum number of geometries in the response. If more geometries satisfy the search/filter criteria, they will be suppressed.
It is undefined, which of the matching geometries are returned, unless this parameter is used together with
|callback||No||Specifies the function used to wrap the JSON response.|
|meta||No||Send with value=1 to get the response geometries framed with meta information like layer and tile id. Default = no meta data.|
