Answer 1

The code to do this is fairly straightforward - in your webhook fulfillment you'll need a Firebase database object, which I call fbdb below. In your Intent handler, you'll get a reference to the location you want to change and make the change.
In Javascript, this might look something like this:
app.intent('value.update', conv => {
var newValue = conv.prameters.value;
var ref = fbdb.ref('path/to/value');
return ref.set(newValue)
.then(result => {
return conv.ask(`Ok, I've set it to ${newValue}, what do you want to do now?`);
})
.catch(err => {
console.error( err );
return conv.close('I had a problem with the database. Try again later.');
});
return
});
The real problem you have is what user you want to use to do the update. You can do this with an admin-level connection, which can give you broad access beyond what your security rules allow. Consult the authentication guides and be careful.

I am actually working on a project using Dialogflow webhook and integrated Firebase database. To make this posible you have to use the fulfilment on JSON format ( you cant call firebasedatabase in the way you are doing)
Here is an example to call firebase database and display a simple text on a function.
First you have to take the variable from the json.. its something loike this (on my case, it depends on your Entity Name, in my case it was "tema")
var concepto = request.body.queryResult.parameters.tema;
and then in your function:
'Sample': () => {
db.child(variable).child("DESCRIP").once('value', snap => {
var descript = snap.val(); //firebasedata
let responseToUser = {
"fulfillmentMessages": [
{ //RESPONSE FOR WEB PLATFORM===================================
'platform': 'PLATFORM_UNSPECIFIED',
"text": {
"text": [
"Esta es una respuesta por escritura de PLATFORM_UNSPECIFIED" + descript;
]
},
}
]
}
sendResponse(responseToUser); // Send simple response to user
});
},
these are links to format your json:

And finally this is a sample that helped a lot!!

after searching out i find guide which can help on this :
we need to first create chat bot on dialogflow/ api.pi
Then need to train our bot and need to use webhook as fullfillment in
response.
Now we need to setup firebase-tools for sending reply and doing
changes in firebase database.
At last we need to integrate dialogflow with google assistant using google-actions
Here is my sample code i used :
`var admin = require('firebase-admin');
const functions = require('firebase-functions');
admin.initializeApp(functions.config().firebase);
var database = admin.database();
// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
//
exports.hello = functions.https.onRequest((request, response) => {
let params = request.body.result.parameters;
database.ref().set(params);
response.send({
speech: "Light controlled successfully"
});
});`
