Our In-App JS Library allows you to leverage key functionalities whilst creating your In-App with our HTML Editor., such as tracking user actions, or prompting them for permissions. In summary, you can do:

Track Actions
Prompt for location and prompt for permissions for push
Tag Users
Send Outcomes
Close the In-App

The Basics

In order to work with our In-App JS Library you need to specify the following:

data-onesignal-unique-label - add this to the elements you are wanting to track, with a unique label. For example.

<button class="tag-user" data-onesignal-unique-label="my-tag-user-button">Tag User</button>

QuerySelector - call actions based on when a user has clicked or engaged with your in-app

document.querySelector(".tag-user").addEventListener("click", function(e) {
  OneSignalIamApi.tagUser(e, { fiz: "baz" });
});

FAQ

Does Tag Substitution work for HTML IAMs?

Tag substitution will work for most HTML elements but will not work within script tags.
Regular liquid syntax, like this will work: <div>Hi there {{ name | default: 'you' }}!</div>
Here, the name OneSignal tag will be replaced with the device's value for that tag, with ‘you’ being the default value if that tag isn’t set.

Tag substitution will work for:

text displayed to the end user (text within a div, p, li, etc)
in <style> tags i.e. body { background-color: "{{ favorite_color | default: '#fff' }}"; }
HTML element attributes which take a url:
- elements with an href attribute
- elements with a src attribute
- action attribute on <form>
- data attribute on <object>

Tag substitution will NOT work within <script> tags

Tag substitution does not work when using the "Send Test Message" button. You will need to test with a test user segment.
