OneSignal has support for custom tags, to categorize and segment your users. Tags are name-value pairs of strings. More info at https://documentation.onesignal.com/docs/data-tags.

You may get and set these tags programmatically using javascript, or alternatively expose a native UI where users can toggle pre-specified tags on/off. 

Javascript method

Get tags

window.location.href = 'gonative://onesignal/tags/get?callback=functionName';

//functionName will get called with an object like:
{
 success: true,
 tags: {
   tag1: "value1"
 }
}
//If there is an error retrieving tags, success will be false.

Set tags

var tags = {
 name1: 'value1',
 name2: 'value2'
};

window.location.href = 'gonative://onesignal/tags/set?tags=' + encodeURIComponent(JSON.stringify(tags));

//You may set value to an empty string to delete an existing tag.
