    }
    {:reply, welcome_message}

Add the handler to supervisor

defmodule MyApp.Application do
  use Application

  def start(_type, _args) do

    children = [
      worker(MyApp.Handler, ["/webhook/viber", 8000])
    ]

    opts = [strategy: :one_for_one, name: MyApp.Supervisor]
    Supervisor.start_link(children, opts)
  end
