…fetch
UrlFetchApp.fetch(url, params);
This service allows scripts to access other resources on the
web by fetching URLs. A script can use the UrlFetch service
to issue HTTP and HTTPS requests and receive responses.
The UrlFetch service uses Google's network infrastructure
for efficiency and scaling purposes.

… for Google Docs and Sheets
Android add-ons are apps that can be called
from Google Docs or Google Sheets editor apps,
and are built by developers to enhance or extend
the capabilities of those editors.

27. “
Execution API...
The Execution API is a REST interface that lets a
third-party application call a function defined in
an Apps Script project and receive a response.
This API lets you expose the full utility of Apps
Script to any application, including Android and
iOS apps.

32. A simple data collection and email example
● Google Drive Storage Folders
● Google Sheet - Data Source
● Google Slides Template (Used to generate .PDF)
● Source Code
● Deployed Web App

33. Client Side: Making AJAX like call
<script>
function handleFormSubmit(formObject) {
google.script.run.withSuccessHandler(updateUrl)
.processForm(formObject);
}
</script>

34. Server Side: Getting the user’s email
// able to get email of who is using the form
data.engineer = Session.getEffectiveUser().getEmail();

35. Server Side: Adding a file from a form to Google Drive
// we get our Pics folder
var folder = DriveApp.getFolderById('0B6GkLMU9sHmLejN2R0xUaVJfVjA');
var formBlob = formObject.myPhoto;
// sending image file to our Google Drive folder
var imgFile = folder.createFile(formBlob);

36. Server Side: Writing data to a Google Sheet
// Reading a Google Sheet
var sheet = SpreadsheetApp.openById('1ANtlQPLPpC…vOIqR4wYayWdVZU4')
.getActiveSheet();
// writing the data to the sheet - each row []
var towrite = [formObject.name, … new Date(), imgFile.getUrl()];
// getRange(Integer row, Integer column, Integer numRows, Integer
numColumns) : Range
sheet.getRange(row+1, 2, 1, towrite.length).setValues([towrite]);

37. Server Side: Getting Slides as PDF and emailing as attachment
// Sending a copy of the cert as pdf
// https://developers.google.com/apps-script/reference/mail/mail-app
MailApp.sendEmail('m.hawksey@gmail.com', 'Attachment example',
'Certificate attached.', {
name: 'Automatic Emailer Script',
attachments: [DECK.getAs(MimeType.PDF)]
});

38. Server Side: Getting Slides as PDF and emailing as attachment
