403 on Google Action push notification request - jwt

Question

I'm trying to perform a push notification for Google Actions Intent.
Thus far, I've followed the instructions here: https://developers.google.com/actions/assistant/updates/notifications#send_notifications
This is my resulting code:
const {google} = require('googleapis');
var request = require('request');
const key = require('./bot.json');
module.exports = async function (context, myQueueItem) {
context.log('JavaScript queue trigger function processed work item', myQueueItem);
let jwtClient = new google.auth.JWT(
key.client_email, null, key.private_key,
['https://www.googleapis.com/auth/actions.fulfillment.conversation'],
null
);
jwtClient.authorize((err, tokens) => {
// code to retrieve target userId and intent
let notif = {
userNotification: {
title: [message],
},
target: {
userId:[obtained from permission request],
intent: [name of intent],
// Expects a IETF BCP-47 language code (i.e. en-US)
locale: 'en-US'
},
};
request.post('https://actions.googleapis.com/v2/conversations:send', {
'auth': {
'bearer': tokens.access_token,
},
'json': true,
'body': {'customPushMessage': notif},
}, (err, httpResponse, body) => {
console.log(body);
console.log(httpResponse.statusCode + ': ' + httpResponse.statusMessage);
});
});
};
//module.exports(console, "Test");
This results in a 403 from the notification service. Is this because of the user id, intent name or jwtoken that was generated?

Answer 1

Following are the steps we need to check before sending the push notification
Check your Google permission settings
In order to test the Action, you need to enable the necessary permissions.
Go to the ‘Activity Controls' page (https://myaccount.google.com/activitycontrols).
Sign in with your Google account, if you have not already done so.
Ensure that the following permissions are enabled:
a.Web & App Activity
b.Device Information
c.Voice & Audio Activity
2.Target intent name should be added into the Implicit invocation field.
with enabled push notification.
3.use the same email id in your google assistant which you had used for login in GCP.
