As an app marketer, you could surely use some superpowers. As experts in push
notifications, we can grant you one: the ability to modify your app’s content
based on how users react to your pushes. Sounds like magic? It’s actually pure
technology you can master on your own, using Pushwoosh Custom Data Builder with
Data Keys.
To begin with…
What is Custom Data?
It is configurable data that you can send encoded in a push notification to your
chosen user segments. When they engage with your message,
Custom Data
changes the appearance of your application for them.
How can you manage your app with Custom Data?
1. Reward users who engage with push notifications
Each time a user opens a push you send them (and each time they don’t),
Pushwoosh can track it. Use this knowledge to your advantage: make dedicated
offers to those who engage with your communications.
For example, you can provide users who opened your push with a special three-day
trial. And with another push with Custom Data, you can suggest a seven-day
trial to a different user group.

Using this approach, you can segment your audience by their engagement, test
different offers against each other, and strengthen your bonds with the most
active recipients.

2. Test a new section/module in your application
With Custom Data, you can open a new feature for beta testing. Select a target
group and send them a push notification announcing the added functionality. If a
user clicks on the message, they will access the section you opened exclusively
for them.
3. Update your application proactively
In some cases, you may need to update your application on users’ devices without
waiting for them to take any action at all.
A
Silent Push
with Custom Data is perfect for this. You can send it to your entire userbase or
choose a specific user segment. The push will get opened automatically. It will
launch your application in the background mode and update its content within a
minute. No action required from your users.
Couldn’t you do all of these with Custom Data before?
You certainly could:
- If you were tech-savvy or had a developer always at your service.
Custom Data was only sent in the JSON format, and to organize it, you had to
follow some strict rules.

- If you were impeccably attentive.
Custom Data is case-sensitive, and when you use it, you have to pay extra
attention to capitalization, not to mention the hyphen vs. dash dilemma.
It sounds like a no-brainer, but in the rush of the editorial, many news and
sports media struggle to enter each and every character correctly.
All in all, Custom Data puzzled quite a few of our customers with no technical
background. We decided to ease things up for marketing, content, and even
development teams, so now…
Custom Data is made simple and error-free
Pushwoosh has introduced the Custom Data Builder to help users fill in the
fields with correct Custom Data and even preview the ultimate push they are
going to send.
- Get your developer preset the possible parameters as Data Keys.

- Let a marketing manager, content writer, or editor use Custom Data
Builder to enter Custom Data in the notification.
They don’t have to figure out the JSON code — they switch to the simple mode
instead.

They don’t have to type in any case-sensitive parameters — they choose from the
preset values instead.

The resulting text looks more comprehensible to a non-tech-savvy professional.
The risk of an error is minimum, and the time needed to work with Custom Data is
reduced too. Complex actions needed for app management are now a task you can
share with any member of your marketing or editorial team. See for yourself:
