Alexa Geographic location - aws-lambda

Question

I am trying to get geographic location in an Alexa skill.
I have enabled location services in the Alexa console and I have authorized the skill to send geographic location.
The message I receive is the following:
{
"context": {
"Extensions": {
"available": {}
},
"System": {
"application": {
"applicationId": "..."
},
"device": {
"supportedInterfaces": {},
"deviceId": "..."
},
"apiEndpoint": "https://api.eu.amazonalexa.com",
"user": {
"userId": "...",
"permissions": {
"scopes": {
"alexa::devices:all:geolocation:read": {
"status": "GRANTED"
}
},
"consentToken": "..."
}
},
"apiAccessToken": "...",
"unit": {
"unitId": "..."
}
}
},
"version": "1.0",
"session": {
"application": {
"applicationId": "..."
},
"user": {
"userId": "...",
"permissions": {
"scopes": {
"alexa::devices:all:geolocation:read": {
"status": "GRANTED"
}
},
"consentToken": "..."
}
},
"new": true,
"sessionId": "..."
},
"request": {
"requestId": "...",
"locale": "it-IT",
"intent": {
"name": "MyIntent",
"confirmationStatus": "NONE"
},
"type": "IntentRequest",
"timestamp": "2021-01-28T07:39:53Z"
}
}
As you may see, the geographic location is GRANTED but the Geolocation field described here is completely missing.

Answer 1

You're correct on geolocation not being available for most Echo devices. Stationary devices only provide the registered address, not geographic coordinates.

You can, however use a "geocoding" service to convert most addresses to coordinates. For example Google Maps has a geocoding API.
