This is a 15-20 minute tech talk designed for those who wish to use Google APIs, but don't know how to get started quickly. This session introduces developers to two distinct ways of accessing our APIs, the standard HTTP-based REST APIs or Google Apps Script, a customized JS environment which provides Google API access via objects. It concludes with some inspirational app ideas of what you can build using Google Cloud APIs (covering both GCP & G Suite).

Using Google (Cloud) APIs (meaning GCP & G Suite APIs) Wesley Chun Developer Advocate, Google Adjunct CS Faculty, Foothill College G Suite Dev Show goo.gl/JpBQ40 About the speaker ● Developer Advocate, Google Cloud ● Mission: enable current and future developers to be successful using Google Cloud and other Google developer tools, APIs, and platforms ● Videos: host of the G Suite Dev Show on YouTube ● Blogs: developers.googleblog.com & gsuite-developers.googleblog.com ● Twitters: @wescpy, @GCPcloud, @GoogleDevs, @GSuiteDevs ● Background ● Software engineer & architect for 20+ years ● One of the original Yahoo!Mail engineers ● Author of bestselling "Core Python" books (corepython.com) ● Teacher and technical instructor since 1983 (all ages) ● Fellow of the Python Software Foundation ● AB Mathematics & CMP Music, UC Berkeley; MSCS UC Santa Barbara
Agenda and Why ● Not enough cloud computing in engineering curriculum ● Need to prep next-generation cloud-ready workforce ● Using APIs should be a nativeskill of new grads ● Introduction to Google Cloud (APIs) ● Using Google (Cloud) REST APIs ● Using Google Apps Script ● Inspirational app ideas (both GCP & G Suite APIs) 1 Introduction to Google Cloud (APIs) GCP and G Suite

How to access Google APIs ● Two ways primarily ○ HTTP-based REST APIs (lower-level) ■ Need either simple API keys or OAuth2 client IDs ■ Any client library supported language ● Python, Java, JS, PHP, Go, Ruby, C#, Dart, etc. ○ Google Apps Script (higher-level) ■ Use APIs as objects in customized JS environment ● No need to code OAuth nor HTTP ■ Access 40+ Google APIs/services 2 Using Google (Cloud) HTTP-based REST APIs Short Python code snippets using GCP & G Suite APIs API key (public data) vs. OAuth2 access (private data)
The first word on Security Authentication ("authn") vs authorization ("authz") ● authn: you are who you say you are ○ login & passwd ○ handprint authentication ○ retina scan ● authz: okay, you are who you say you are, but can you haz data? ○ OAuth2 - mostly authz, but some authn ○ Mostly about 3rd-party access to data ○ Users must give YOUR app access to THEIR data ○ Most of the time when you see "auth", it refers to authz Developers Console (devconsole)
