Schedule long-running jobs
with Background Jobs

CLOUD MODULES
Easy third-party integration
with pre-built modules
Send email Take payments
Add SMS to your
app
Connect with any RESTful service
using Parse.Cloud.httpRequest

BACKGROUND JOBS
Schedule long-running jobs
For operations that need
to be performed regularly
or on command
Longer timeouts—
15 minutes
Trigger from the web
UI or REST endpoint

A SIMPLE JOB

A SIMPLE JOB
Parse.Cloud.job(”lowercaseallthethings”, function (request, status) {
// Set up to modify user data
Parse.Cloud.useMasterKey();
// Query for all users
var query = new Parse.Query(Parse.User);
query.each(function(user) {
// Set and save the change
user.set(”name”, user.name.toLowerCase());
return user.save();
}).then(function() {
ac tempor // vitae, Set the commodo job’s success a nisi. and Morbi error tincidunt statuses
felis lacus, nec
status.success(”All users now have lowercase names”);
congue }, tortor function(consectetur error) {
id. Lorem ipsum dolor sit amet,

}

Parse.enableLocalDatastore();
ParseQuery<ParseObject> query = ParseQuery.getQuery(“GameScore");
query.orderByDescending(“score”);
query.fromLocalDatastore();
query.findInBackground(new FindCallback<ParseObject>() {
...
});
Parse Local Datastore

Parse Config
Create and manage configuration variables for your apps from the Parse Dashboard

INSTALLATIONS
1 device + 1 install of your app = 1 Installation
Pushes are sent to
Installations
Add relationships to objects
of interest, e.g. users
ParseInstallation.getCurrentInstallation().saveInBackground();

PUSH TARGETING
Channels vs Queries
Target stable interest
groups with channels
Send pushes to ad-hoc or
changing groups by
pushing to queries
To push to a query, your
Installation class must point
to the class of interest

PUSH TO A CHANNEL

PUSH TO A CHANNEL
ParsePush push = new ParsePush();
push.setChannel(”PSGFans”);
push.setMessage(”The game starts now on channel 5!”);
push.sendInBackground();

PUSH TO A QUERY

PUSH TO A QUERY
ParseQuery pushQuery = ParseInstallation.getQuery();
pushQuery.whereEqualTo(”hasCheckedInToVenue”, true);
ParsePush push = new ParsePush();
push.setQuery(pushQuery);
push.setMessage(”The keynote is about to start!”);
push.sendInBackground();

CUSTOM EVENTS
Events + Dimensions
Create your own events
and track custom user
behaviour
Slice and dice your data
however you choose
Save additional
parameters with
dimensions

CUSTOM EVENTS
event: "signedUp"
dimensions: {
gender: "f",
source: "web",
friendsUsingApp: "35",
wasReferred: "true"
}

CUSTOM EVENTS

CUSTOM EVENTS
Map<String, String> dimensions = new HashMap<String, String>();
// Add key-value pairs to be saved alongside event
dimensions.put(”gender”,”f”);
dimensions.put(”source”,”web”);
// Consider using buckets to meaningfully segment events
dimensions.put(”friendsUsingApp”,”25-50”);
dimensions.put(”wasReferred”,”true”);
ParseAnalytics.trackEvent(”signup”, dimensions);

CUSTOM EVENTS
Knowledge is Power
Is the first level of my
game too hard?
Why aren’t people
completing purchases
in my app?
How successful was our
last push campaign?
