URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in JSON format.

CellTowers

Retrieves an estimated device position by resolving measurement data from cellular radio towers. The position is resolved using HERE's cellular-based solver.

Type: CellTowers object

Required: No

Gnss

Retrieves an estimated device position by resolving the global navigation satellite system (GNSS) scan data. The position is resolved using the GNSS solver powered by LoRa Cloud.

Type: Gnss object

Required: No

Ip

Retrieves an estimated device position by resolving the IP address information from the device. The position is resolved using MaxMind's IP-based solver.

Type: Ip object

Required: No

Timestamp

Optional information that specifies the time when the position information will be resolved. It uses the Unix timestamp format. If not specified, the time at which the request was received will be used.

Type: Timestamp

Required: No

WiFiAccessPoints

Retrieves an estimated device position by resolving WLAN measurement data. The position is resolved using HERE's Wi-Fi based solver.

Type: Array of WiFiAccessPoint objects

Required: No
