Firebase new v1 api to send push notification

To send push notification we need

1. new url
2. access token
3. new payload structure

create_access_token.js

var { google } = require("googleapis");
var MESSAGING_SCOPE = "https://www.googleapis.com/auth/firebase.messaging";
var SCOPES = [MESSAGING_SCOPE];
function getAccessToken() {
	return new Promise(function (resolve, reject) {
		var jwtClient = new google.auth.JWT(
			"[email protected]",
			null,
			"put_your_private_key_from_json",
			SCOPES,
			null
		);
		jwtClient.authorize(function (err, tokens) {
			if (err) {
				reject(err);
				return;
			}
			resolve(tokens.access_token);
		});
	});
}

getAccessToken().then(function (result) {
	console.log(result);// copy this access token
});
