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)

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

API key (public data) vs. OAuth2 access (private data)

5.
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)

6.
● Manage your projects
● Obtain application credentials
● En-/disable Google APIs

List (first 100) files/folders in Google Drive
from __future__ import print_function
from apiclient import discovery
from httplib2 import Http
from oauth2client import file, client, tools
SCOPES = 'https://www.googleapis.com/auth/drive.readonly.metadata'
store = file.Storage('storage.json')
creds = store.get()
if not creds or creds.invalid:
flow = client.flow_from_clientsecrets('client_secret.json', SCOPES)
creds = tools.run_flow(flow, store)
DRIVE = discovery.build('drive', 'v3', http=creds.authorize(Http()))
files = DRIVE.files().list().execute().get('files', [])
for f in files:
print(f['name'], f['mimeType'])

Migrate SQL data to a Sheet
# read SQL data then create new spreadsheet & add rows into it
FIELDS = ('ID', 'Customer Name', 'Product Code',
'Units Ordered', 'Unit Price', 'Status')
cxn = sqlite3.connect('db.sqlite')
cur = cxn.cursor()
rows = cur.execute('SELECT * FROM orders').fetchall()
cxn.close()
rows.insert(0, FIELDS)
DATA = {'properties': {'title': 'Customer orders'}}
SHEET_ID = SHEETS.spreadsheets().create(body=DATA,
fields='spreadsheetId').execute().get('spreadsheetId')
SHEETS.spreadsheets().values().update(spreadsheetId=SHEET_ID, range='A1',
body={'values': rows}, valueInputOption='RAW').execute()

BigQuery: querying Shakespeare words
TITLE = "The top 10 most common words in all of Shakespeare's works"
QUERY = '''
SELECT LOWER(word) AS word, sum(word_count) AS count
FROM [bigquery-public-data:samples.shakespeare]
GROUP BY word ORDER BY count DESC LIMIT 10
'''
rsp = BQ.query(body={'query': QUERY}, projectId=PROJ_ID).execute()
print('n*** Results for %r:n' % TITLE)
for col in rsp['schema']['fields']: # HEADERS
print(col['name'].upper(), end='t')
print()
for row in rsp['rows']: # DATA
for col in row['f']:
print(col['v'], end='t')
print()

What can you do with this?
Accessing maps from
spreadsheets?!?
goo.gl/oAzBN9
This… with help from Google Maps & Gmail
function sendMap() {
var sheet = SpreadsheetApp.getActiveSheet();
var address = sheet.getRange("A2").getValue();
var map = Maps.newStaticMap().addMarker(address);
MailApp.sendEmail(EMAIL, "Map", map.getMapUrl());
}

Resources for Higher Education
● Education grant program
○ Teaching grants (per-course basis)
■ $50USD for students
■ $100USD for faculty & TAs
■ You'll barely use any of it… key: no need to give Google a credit card
○ Research grants
■ Larger amounts, granted for longer period of time
○ Turnaround time: 3-4 business days
● Teacher center
