Answer 1

Worked for me...

Add this gem 'fcm' into your gemfile, run the command bundle install .

Create a method and paste this:

require 'fcm'

fcm = FCM.new(server_key) # Find server_key on: your firebase console on web > tab general > web api key

registration_ids= [device_keys] # Array of keys generated by firebase for devices 

options = {
        priority: "high",
        collapse_key: "updated_score", 
        notification: {
            title: "Message Title", 
            body: "Hi, Worked perfectly",
            icon: "myicon"}
        }

response = fcm.send(registration_ids, options)

You can find this fcm gem that allows you to send notification with Firebase Cloud Messaging.

require 'fcm'

fcm = FCM.new("my_api_key")
# you can set option parameters in here
#  - all options are pass to HTTParty method arguments
#  - ref: https://github.com/jnunemaker/httparty/blob/master/lib/httparty.rb#L29-L60
#  fcm = FCM.new("my_api_key", timeout: 3)

registration_ids= ["12", "13"] # an array of one or more client registration tokens
options = {data: {score: "123"}, collapse_key: "updated_score"}
response = fcm.send(registration_ids, options)

There is no need to use Gem, it does not work for my application. but I'm using React to use POST Method ( https://fcm.googleapis.com/fcm/send ) with the following header contents:

{
    server_key: web_api_key_on_console_web
},

body: {
    to: Mobile_token_created_by_phone,
    notification: {
        title: "Judul",
        body: "Isi pesan"
    },
}
