In this session, we will discuss how to measure and track users' actions in your app against key metrics and trends such as new vs. returning users, app revenue, user retention, and custom in-app behavior events. We will also show you how to leverage this data to bring them back to your app by sending automatic push notifications, SMS, and emails. AWS DevDay San Francisco, June 21, 2016.

12. Provider

Token Request
Amazon
SNS
Platform Application
“Token”
Platform Endpoint
- Upload Certificates, API Keys, etc.
Upload Token
- AKA “Create Platform Endpoint”
Platform Application Lifecycle

13. APNS
Signing Request
App Creation (developer.apple.com)
• BundleID
• Push Enabled
Certificate Creation
Provisioning Profile
Test Connection
Configuring Platform Applications
GCM
Components
• Google Developer Project
• Mobile App
• Backend Application (SNS)
Credentials
• Sender ID (aka “Project Number”)
• API Key (authorization)
• HTTP header or XMPP auth request
• AppID

14. Demo: SNS

15. Authorization
Cognito Identity
• Create Unique Identities
• Roles
• Authenticated
• Unauthenticated
• Temporary, limited
credentials
Cognito User Pools
• Fully managed User
Directory
• Federate with Identity
• Pass to API Gateway
• Sign-up/Sign-in Workflows

16. Fine-grained control
Send to Mobile Analytics
Sync Datasets across devices
Add Token to SNS
Add email/phone to SNS

18. Demo: Cognito

19. Native
Interrogates app lifecycle
• Background queue filled with
Session and Custom Events
• Session events batched & sent
Backgrounded time > AWSValueSessionResumeDelay
• Custom events sent anytime
• Best practice: use onPause,
onStop, onResume
SDK Session Management
Web
Configure default session length
Force event submission anytime
Window.localStorage ensures
persistence through browser/tab
exiting

20. Enhancing JavaScript Sessions
Debate: Apples vs. Oranges?
Modern browsers offer visibilitychange() event:
https://developer.mozilla.org/en-US/docs/Web/Events/visibilitychange
extendSession()
stopSession()

21. Delivery Status
Written to CloudWatch Logs
• 2-week graph of Sent vs Delivered
• Publishers can also write to
CloudWatch w/ custom metric
Tracking Metrics
Application Events
Publish to Topics
• Lambda, HTTP/S, etc.

22. Publishing to SNS

23. iOS
// if your app had to be launched. A particular key is set in options to
specify that a push notification was received-
application:didFinishLaunchingWithOptions:
// if you app was already running in the background
application:didReceiveRemoteNotification:
Metrics: Open on Push
Android

24. Demo: Custom Metrics

25. Personalization
Engagement is all about personalization
• Automatic push if they installed but never did action X
• Push to group of users (Topic) with a custom message
• “Discount today click here!”
• Push to individuals with customized messages
• "Hey John we noticed you looked at product X but didn't
purchase"

26. TODO: Lambda function reading DDB list of users that
looked at product X then send push notifications that they
might be interested in product Y
• This will be a good example showing you can push to
platform endpoints not just topics
• Will also show this with Lambda cron scheduling to
publish to SNS

27. Tying it all together: Request tracking
