Setup Integration in Ruby on Rails

To send slack notifications, we are going to use a gem called slack-notifier.

So just add it in your Gemfile:

gem 'slack-notifier', '~> 2.4' # Change it with the latest version

And run:

bundle install

Now run rails c in your terminal and type:

notifier = Slack::Notifier.new "WEBHOOK_URL",
           channel: "#random",
           username: "notifier"

notifier.ping "Hello random"
# => will ping the "#random" channel

To get more information about the gem, you can visit this url.

So go ahead and give it a try! And if you get stuck, don't hesitate to reach out.
