 The Azure Maps [GET Geofence] and [POST Geofence] API allow you to retrieve proximity of a coordinate relative to a provided geofence or set of fences. This article details how to prepare the geofence data that can be used in the Azure Maps GET and POST API.

+The data for geofence or set of geofences, represented by the `Feature` Object and `FeatureCollection` Object in `GeoJSON` format, is defined in [rfc7946]. In Addition to it:
 
 * The GeoJSON Object type can be a `Feature` Object or a `FeatureCollection` Object.
 * The Geometry Object type can be a `Point`, `MultiPoint`, `LineString`, `MultiLineString`, `Polygon`, `MultiPolygon`, and `GeometryCollection`.
 * All feature properties should contain a `geometryId`, which is used for identifying the geofence.
 * Feature with `Point`, `MultiPoint`, `LineString`, `MultiLineString` must contain `radius` in properties. `radius` value is measured in meters, the `radius` value ranges from 1 to 10000.
-* Feature with `polygon` and `multipolygon` geometry type does not have a radius property.
+* Feature with `polygon` and `multipolygon` geometry type doesn't have a radius property.
 * `validityTime` is an optional property that lets the user set expired time and validity time period for the geofence data. If not specified, the data never expires and is always valid.
-* The `expiredTime` is the expiration date and time of geofencing data. If the value of `userTime` in the request is later than this value, the corresponding geofence data is considered as expired data and is not queried. Upon which, the geometryId of this geofence data will be included in `expiredGeofenceGeometryId` array within the geofence response.
-* The `validityPeriod` is a list of validity time period of the geofence. If the value of `userTime` in the request falls outside of the validity period, the corresponding geofence data is considered as invalid and will not be queried. The geometryId of this geofence data is included in `invalidPeriodGeofenceGeometryId` array within geofence response. The following table shows the properties of validityPeriod element.

-Following is a sample request body for a geofence represented as a circle geofence geometry in `GeoJSON` using a center point and a radius. The valid period of the geofence data starts from 2018-10-22, 9AM to 5PM, repeated every day except for the weekend. `expiredTime` indicates this geofence data will be considered expired, if `userTime` in the request is later than `2019-01-01`.
