Why Google APIs!

•  Run on Google’s infrastructure •  Global network: Google has one of the largest and most advanced computer networks. •  Redundancy: Multiple locations across the globe provides strong redundancy. •  Cutting-edge Technology: Access to Google’s technology innovations faster. (e.g Spanner

and Flume)

•  Focus on your product •  Managed services: Let Google worry about infrastructure while you focus on your code •  Developer tools and SDKs: Google provides API client libraries, etc •  Console and administration: See and manage all of your applications from a single console

•  Mix and match •  Use Google APIs to quickly enable a wide range of functionality for your application. You

don’t need to build these from scratch, just take advantage of easy integration

RESTful in a nutshell!

The REST architecture is based on the following simple ideas

•  REST uses URIs to refer to and to access resources •  REST is built on top of the stateless HTTP 1.1 protocol •  REST uses HTTP commands to define operations HTTP commands have precise semantics

•  GET lists or retrieves a resource at a given URI •  PUT replaces or updates a resource at a given URI •  POST creates a resources at a given URI •  DELETE removes the resources at a given URI

Authorized Access to APIs with OAuth!

Google APIs Explorer?!

“The Google APIs Explorer is a tool that helps you explore various Google APIs interactively”

•  Credentials to access an API are not needed to use the APIs Explorer •  The APIs Explorer uses its own API key whenever it makes a request
