According to this page https://developers.google.com/maps/reporting-and-monitoring/reporting?hl=en#usage-tracking-per-channel
there is opportunity to use param channel for tracking usage of api.
How I should to set this param (channel) for tracking usage of api? Or this functionality not working in Routes API?
When I set param channel in request
curl -X POST -d '{
"origin":{
"location":{
"latLng":{
"latitude": 37.419734,
"longitude": -122.0827784
}
}
},
"destination":{
"location":{
"latLng":{
"latitude": 37.417670,
"longitude": -122.079595
}
}
},
"travelMode": "DRIVE",
"routingPreference": "TRAFFIC_AWARE",
"departureTime": "2023-10-15T15:01:23.045123456Z",
"computeAlternativeRoutes": false,
"routeModifiers": {
"avoidTolls": false,
"avoidHighways": false,
"avoidFerries": false
},
"languageCode": "en-US",
"units": "IMPERIAL"
}' \
\-H 'Content-Type: application/json' -H 'X-Goog-Api-Key: YOUR-API-KEY' \
\-H 'X-Goog-FieldMask: routes.duration,routes.distanceMeters,routes.polyline.encodedPolyline' \
'https://routes.googleapis.com/directions/v2:computeRoutes?key=YOUR-API-KEY&**channel**=3'
I get response with message "Invalid JSON payload received. Unknown name "channel": Cannot bind query parameter. Field 'channel' could not be found in request message."
