For implementation with Ruby, you can use the Gem of a third-party vendor. The Gem is available here. Please note that this has not been tested by us.

require "ruby_sms"
sms = RubySms.new(api_key: "1234123", user: "user@email.com")
response = sms.send(message: "your message", to: "+49178223", delay: false)
if response.success? 
  puts "Sms deliverd " 
else
  puts response.errors
end
