Are you trying to connect Block.io API via your Heroku app? You've found the right article. 


Here is an example of how to use block.io with a proxy:

https://github.com/BlockIo/gem-block-io/blob/master/examples/proxy.rb

You would need to modify that example as such:


proxy = URI(ENV["QUOTAGUARDSTATIC_URL"])

blockio = BlockIo::Client.new(:api_key => ENV['API_KEY'], :pin => ENV['PIN'], :version => 2, :proxy => {     
    hostname: proxy.host,
    port: proxy.port,
    username: proxy.user,
    password: proxy.password    
  }
)
