Report request

Service version: 1
Last edit: 2022.09.01

Purpose

Geofencing Reports are the central part of our Geofencing service. Each Geofencing Report contains information about provided position's surrounding fences that exist in the selected project.

This endpoint provides:

  • A short summary containing a unique project id, the position for which the Geofencing Report is generated, and a radius used to create the Geofencing Report expressed in meters.
  • A list of fences that the request point is inside of, sorted by distance in ascending order.
  • A list of fences that the request point is outside of, sorted by distance in ascending order.

Request data

HTTPS method: GET

  • Constants and parameters enclosed in curly brackets { } must be replaced with their values.
  • Please see the following Request parameters section with the required and optional parameters tables for their values. The generic request format is as follows.

GET URL request format

GET
GET URL request format
https://{baseURL}/geofencing/{versionNumber}/report/{projectId}?key={Your_API_Key}&point={longitude,latitude,altitude}&objectId={objectId}&range={range}

GET curl command request format

GET
GET curl command request format
curl 'https://{baseURL}/geofencing/{versionNumber}/report/{projectId}?key={Your_API_Key}&point={longitude,latitude,altitude}&objectId={objectId}&range={range}'

HTTPS method: POST

It's the same type of Geofencing Report as the standard one: Geofencing API Report. If a user uses this POST version, it will detect and save transitions of the provided object.

Important note:

Before a customer can send a position in the report they must give consent for the storing of historical positions .

If consent is given, this endpoint writes the provided position to positions history. To accurately calculate transitions, this endpoint uses the freshest, previous, position from history, regardless which API recorded it.

Request parameters

The following table describes the parameters that can be used in a request.

  • Required parameters must be used or the call will fail.
  • Optional parameters may be used.
  • The order of request parameters is not important.

Required parameters

Description

baseURL
string

The base URL for calling the API.
Value: api.tomtom.com

versionNumber
string

The service version number.
Value: 1

key
string

An API Key valid for the requested service.
Value: Your valid API Key.

point
array (of floats)

A location (in coordinates) for which the Geofencing Report is requested.
Value: An array of floats:

  • longitude

  • latitude

  • altitude (optional)

latitude
float

The latitude coordinate of the point in degrees with a precision of 6 digits after the decimal point.
Value: A latitude coordinate
Unit: degrees
Range: <-90,90>
Reference: See WGS84 datum (World Geodetic System)

longitude
float

Longitude coordinate of the point in degrees with a precision of 6 digits after the decimal point.
Value: A longitude coordinate
Unit: degrees
Range: <-180,180>
Reference: WGS84 datum (World Geodetic System)

altitude
float (optional)

The altitude coordinate of the point expressed in meters, with a precision of 0.1 meter.
Value: An altitude coordinate
Default value: 0
Unit: meters
Range: <-500,15000>
Reference: WGS84 datum (World Geodetic System)

Optional parameters

Description

projectId
string

The unique project id used to generate the Geofencing Report.

  • If no project id is provided, but an object with a default project is provided, that default project is used for this request.

  • If no project is provided and the object has no default project, a HTTP 400 error is returned with that information.

  • If a project id is provided then it takes precedence over object's default project.


Value: A UUID
Default value: The object 's default project if it exists.

objectId
string

The object unique id used to generate a Geofencing Report. If no project id is provided, but the object has a default project, that default project is used for this request.
Value: A UUID

range
float

The radius of a circle around the provided point. This is used to decide whether fences, that do not contain the point, are close enough to report. It does not affect fences that contain the point. If this parameter's value is 0 or not included, only the closest fence is included in the outside element of the response.
Default value: 0
Other value: A circle's radius
Unit: meters
Range: <0,100000>

timestamp
string

The date and time of the position being recorded by the user.
Default value: server timestamp of the request
Value: ISO 8601 format timestamp (YYYY-MM-DDThh:mm:ss)

Response data

The Geofencing Report contains:

  1. A short summary containing:

    • A unique project id.
    • A position generated for the Geofencing Report.

    • A radius used to create the Geofencing Report, expressed in meters.

  2. A list of fences that the request point is inside of, sorted by distance in ascending order. If the object is not inside any fences, the list is empty. If not, each fence entry contains:

    • A unique fence id.
    • A fence name.

    • The distance from the request point to the nearest point on the fence border, represented as a negative value.

    • Coordinates of the nearest point on the fence border.

  3. A list of fences that the request point is outside of, sorted by distance in ascending order. As long as there is at least one outside fence in the requested project, the list contains at least one entry. Each fence entry contains:

    • A unique fence id.
    • A fence name.

    • The distance from the request point to the nearest point on the fence border, represented as a positive value.

    • Coordinates of the nearest point on the fence border.
