post

https://geofencing.hereapi.com/v8/geofence/modify

Modify geometries using an HTTP POST request. After receiving the response, there is a delay of several seconds to compile, store and make the modified geometries available in the service. Note: The level (tile grid size) of the layer can only be changed by re-uploading the whole layer, not as a modification operation.

Query Params

layerId

string

required

Unique identifier for the layer in the format {app_id}.{mapName}.{layerName}. app_id: app_id of the project modifying the layer; mapName: the map into which the layer is uploaded, default = upload the layer into the app_id's default map; layerName: Name of layer to modify, the maximum length of a layer name and the permitted characters can be looked up in the service via resource 'v8/maps/serviceconfiguration'.

action

string

required

Action can be append, update or delete.

Geometries are identified by their unique geometry_id column value.
For an append operation, new geometries in requestBody must not already exist in the layer, and they will be added.
For an update, geometries in requestBody must already exist, and these will be replaced.
All column values must be specified, not only the changes.
For update and delete operation, attribute columns names, sequence order and type must remain unchanged.
For delete operation, the geometries must exist and will be removed. Only the geometry_id column is required for this operation.

wktQuote

string

Defaults to "

Specify the quote character to use. Specifying NONE disables quotes.

ownerAppId

string

Owner app_id that was used to upload a layer. It is mandatory when a granted app_id is used to access the layer.
