In this release, we are making a significant shift from a device-centered model to a user-centered model. This means that instead of identifying devices, we now focus on identifying individual users. This update is part of a larger effort to shift towards a user-oriented omni-channel messaging system.
To facilitate this change, the externalId approach for identifying users is being replaced by the login and logout methods. In addition, the SDK now makes use of namespaces such as User, Notifications, and Slidedown to better separate code.
This guide will walk you through these and other important changes in the version 16 update.
Under the new model, the concept of a "player" is being updated to include three new concepts: users, subscriptions, and aliases.
Users own subscriptions and are identified by aliases which are used to point to users using different alias schemes.
Subscriptions refer to the way in which a user can receive various communication methods offered by OneSignal, including push notifications, SMS, and email.
Aliases are identifiers that point to users and are made up of an alias label and id. Users can have multiple aliases. Consider the need to identify a user with your own application's unique identifier as well as identifiers from other integrated applications.
The SDK will use external_id as the default alias label for the public OneSignal.login("1234") method.
Alias Example:
"aliases": [
{
"label": "external_id",
"id": "1234"
},
{
"label": "my_alias",
"id": "5678"
}
]
// WebSDK-specific example
{
external_id: "1234",
my_alias: "5678"
}From:
importScripts("https://onesignal.com/sdks/OneSignalSDKWorker.js");To:
importScripts("https://onesignal.com/sdks/web/v16/OneSignalSDK.sw.js");Update any usages of OneSignal.setExternalId to OneSignal.login or OneSignal.logout
From:
OneSignal.setExternalId("myId");To:
OneSignal.login("myId");Use OneSignal.logout(); instead anywhere you have OneSignal.setExternalId(""); or are setting it to null.
Update your code to use the new API. The following namespaces are on the OneSignal object.
Example:
OneSignal.User.addAlias("my_alias", "1234");All user functions are synchronous.
