## URI Request Parameters
The request does not use any URI parameters.
## Request Body
The request accepts the following data in JSON format.
** [CellTowers](#API_GetPositionEstimate_RequestSyntax) **
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](API_CellTowers.md) object
Required: No
** [Gnss](#API_GetPositionEstimate_RequestSyntax) **
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](API_Gnss.md) object
Required: No
** [Ip](#API_GetPositionEstimate_RequestSyntax) **
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](API_Ip.md) object
Required: No
** [Timestamp](#API_GetPositionEstimate_RequestSyntax) **
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](#API_GetPositionEstimate_RequestSyntax) **
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](API_WiFiAccessPoint.md) objects
Required: No
## Response Syntax
```
HTTP/1.1 200
GeoJsonPayload
```
## Response Elements
If the action is successful, the service sends back an HTTP 200 response.
The response returns the following as the HTTP body.
** [GeoJsonPayload](#API_GetPositionEstimate_ResponseSyntax) **
The position information of the resource, displayed as a JSON payload. The payload is of type blob and uses the [GeoJSON](https://geojson.org/) format, which a format that's used to encode geographic data structures. A sample payload contains the timestamp information, the WGS84 coordinates of the location, and the accuracy and confidence level. For more information and examples, see [Resolve device location (console)](https://docs.aws.amazon.com/iot/latest/developerguide/location-resolve-console.html).
## Errors
For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).
** AccessDeniedException **

HTTP Status Code: 403
** InternalServerException **
An unexpected error occurred while processing a request.
HTTP Status Code: 500
** ResourceNotFoundException **
Resource does not exist.
** ResourceId **
Id of the not found resource.
** ResourceType **
Type of the font found resource.
HTTP Status Code: 404
** ThrottlingException **
The request was denied because it exceeded the allowed API request rate.
HTTP Status Code: 429
** ValidationException **
The input did not meet the specified constraints.
HTTP Status Code: 400
