The document discusses exploring Google APIs using Python and JavaScript. It covers an overview of using Google APIs, including accessing APIs through the Google Developers Console and Google API client libraries. It demonstrates accessing Google APIs through Python code examples for both simple and authorized access. The document also provides an overview of Google Apps Script, how it operates in the JavaScript environment, and code demos for accessing Google APIs through Apps Script.

● Overview
● Getting started
● Python
● Live demo(?)
● Wrap-up

5. Part I: Google APIs overview

6. BUT
... wait, there’s more...

8. Part II: Getting Started with Google APIs
Developers Console (devconsole)

13. OAuth2 scenarios
● Varies on application type (where apps located)
○ Web (server) applications
○ Installed (mobile & desktop computers) apps
○ Service accounts (cloud/server-to-server)
○ Client-side (JavaScript) apps
○ Limited-input devices (game consoles, printers, cameras, etc.)
○ developers.google.com/identity/protocols/OAuth2
○ TODAY: command-line script == "Installed"

16. Part III: Using Google APIs with Python
developers.google.com/discovery/libraries
Open source client
libraries for many
languages, not just

17. SIMPLE
AUTHORIZED
API access
Simple API access

18. General OAuth2 process
● Goal: valid access token == 3rd-party API data access
● How OAuth2 works (in general)
○ Step 1: Create OAuth2 credentials in DevConsole
○ Step 2: Send credentials to get access & refresh tokens
○ Step 3: Use access token to make authorized API calls
○ Step 4: Access tokens expire; use refresh to get new one
● developers.google.com/identity/protocols/OAuth2
● Others will be similar (with slight differences)
Authorized API access

19. SIMPLE
AUTHORIZED
Which do you choose?
Part IV: Demo (live would make it interesting)

20. Searching Google+ for social posts
Searching YouTube for videos

21. Listing your files in Google Drive
Use of multiple APIs supported
Simple, authorized, or a mix of both types of APIs; re-uses HTTP client; also see goo.gl/cdm3kZ

22. Write your own or see
github.com/googledrive/zipextractor (JS)
Build a Node.js customized reporting tool with our
Sheets API codelab at g.co/codelabs/sheets (JS)

23. Check out our Node.js Markdown-to-Google Slides
sample app demoing the Slides API

24. Part V: Wrap-up

25. Reference
● Google Developers Console
○ console.developers.google.com
● Google APIs Client Library for Python (2 & 3)
○ pip{,3} install -U google-api-python-client
○ developers.google.com/api-client-library/python
■ .../python/guide/{django,google_app_engine} # special
● Other languages
○ developers.google.com/discovery/libraries
Reference
● Blog + video Resources
○ SETUP & BOILERPLATE
■ goo.gl/RbyTFD (new Google APIs project setup)
■ goo.gl/KMfbeK (common Python boilerplate code review)
○ GOOGLE APIs
■ goo.gl/ZIgf8k and goo.gl/EySSQV (Google Drive API)
■ goo.gl/pFYUQ2 (Gmail API)
■ goo.gl/KuYMiq (Google Calendar API)
■ goo.gl/N1RPwC and goo.gl/U6Oljn (Google Sheets API)
■ goo.gl/o6EFwk (Google Slides API)

26. Alternative 1
● Google Apps Script
○ What is it?
■ Executes as JavaScript in Google's cloud
■ Think “built-in” services vs. traditional API usage
■ Convenient access to G Suite/Google Apps data
■ Can also access other Google+external services
■ developers.google.com/apps-script
○ Video resources
■ goo.gl/1sXeuD (Apps Script intro)
■ goo.gl/oAzBN9 (Google Maps & Gmail APIs)
■ goo.gl/YuwZ0E (YouTube [Data] API)
■ goo.gl/xSzGl4 (Google Forms)
Alternative 2
● What about my favorite HTTP request library?
○ requests
■ python-requests.org
○ So can I use 'requests' to talk to Google APIs?
○ Answer: YES, but...
■ Not many examples out there
■ I found one at gist.github.com/ymotongpoo/1907281
■ BUT look at it, ~80% of code is auth{entic,oriz}ation
■ Client Library hides most of it from you
■ Summary: yes you can, but it'll be a DIY effort

27. Alternatives for other Google APIs
● Most, not all, Google APIs work with standard Client Library
● Other APIs/platforms have their own
○ Google AdWords
■ developers.google.com/adwords/api/docs/clientlibraries
○ Google Maps (Web Services)
■ developers.google.com/maps/web-services/client-library
○ Google Cloud Platform
■ cloud.google.com/python/apis
○ Firebase platform (Android, iOS, Web, C++, Node.js, Java)
■ firebase.google.com/docs/libraries

29. Another Google secret?
+JavaScript
-API “flavor”
+built-in “flavor”
-OAuth2 (you)

30. JS
Not your daddy’s JavaScript

31. Not Node.js either
!=

32. Apps just the beginning
Apps Script powers add-ons

33. Other Google services
But wait, there’s more...
Google Apps services
Admin SDK
Calendar
Contacts
Docs
Drive
Forms
Gmail
Google+ Domains
Groups
Maps
Sites
Sheets
Tasks
Other Google services

Analytics
BigQuery
Fusion Tables
goo.gl
Mirror (Glass)
Prediction
Translate
YouTube
Other services

Automation(i.e., mail merge)

35. Enterprise workflow(i.e., team OoO calendars)
Types of Apps Scripts
● Standalone scripts
○ Script.google.com
○ Google Drive > Create > Script
● Add-ons (Docs, Sheets, Forms) & document-bound scripts
○ Tools > Script editor
○ Add-ons > Get/Manage add-ons
● Simple web apps & Sites-bound gadgets
○ More > Manage Site > Apps Scripts > Add new script

36. Your first Apps Script project

37. OAuth2 flow

42. Confidential & Proprietary
Summary
● We’ve created great technology but can’t build everything(!)
● APIs: our tech available for your apps to integrate with; free?!?
● Access using favorite dev tool via Google APIs Client Library
○ Python, JavaScript (client + Node.js), Java, C#/.NET, Go, Dart, Ruby, PHP
○ Also mobile samples in docs: Android (Java), iOS (Swift, Objective-C)
● Alternative: Google Apps Script
○ More like “built-in” services vs. traditional API usage (above)
○ Convenient access to G Suite/Apps data & other Google+external services
● Build the next great thing!
