Getting started consuming web services in a Ruby on Rails 3 application -

I have done minimal work in this way with PHP and pre-built libraries. Can someone lead me to some resources, best practices, or do I have a quick 101 text type of API to start working with them? Should I use gems? Update: I'm trying to use the Google Books API (non-standardized) specifically. Since there is no client library for this API, I am thinking that other Ruby / Rail developers are working with APIs that do not come with Ruby Library.

Like a link where I can learn something like this or maybe this is probably the name of this process, because I do not know how to search about this topic in Google. Thanks in advance! Can be completed with peer-to-peer discovery and connectivity you are describing Game Kit Framework Originally I thought it works only through Bluetooth, but after watching it immediately, it seems that WiFi is also supported. Hope it helps!
