Client SDK Reference

Comprehensive reference of OneSignal's SDK methods

Some methods below require the OneSignal SDK Versions:

  • Android 4.0.0+
  • iOS 3.0.0+
  • React Native 4.0.0+
  • Flutter 3.0.0+
  • Cordova/Ionic 3.0.0+
  • Unity 3.0.0+

See Mobile SDKs API Migration Guides to upgrade the OneSignal SDK or the old SDK Reference.

Initializing OneSignal

These methods serve as a reference and are just a single step in the set up process. Make sure to follow the steps for your particular configuration here:

//See Android SDK Setup for details https://documentation.onesignal.com/docs/android-sdk-setup
OneSignal.initWithContext(this);
OneSignal.setAppId(ONESIGNAL_APP_ID);
//See iOS SDK Setup for details https://documentation.onesignal.com/docs/ios-sdk-setup
OneSignal.initWithLaunchOptions(launchOptions)
OneSignal.setAppId("YOUR_ONESIGNAL_APP_ID")
//See iOS SDK Setup for details https://documentation.onesignal.com/docs/ios-sdk-setup
[OneSignal initWithLaunchOptions:launchOptions];
[OneSignal setAppId:@"YOUR_ONESIGNAL_APP_ID"];
OneSignal.Default.Initialize("your_app_id");
/* This is for Expo Bare Workflows. If using a managed workflow,
see the Expo set up guide (https://documentation.onesignal.com/docs/react-native-expo-sdk-setup)*/

//Place code in your index.js/main.js
OneSignal.setAppId("YOUR-ONESIGNAL-APP-ID");
//Remove this method to stop OneSignal Debugging 
OneSignal.shared.setLogLevel(OSLogLevel.verbose, OSLogLevel.none);

OneSignal.shared.setAppId("YOUR_ONESIGNAL_APP_ID");

// The promptForPushNotificationsWithUserResponse function will show the iOS push notification prompt. We recommend removing the following code and instead using an In-App Message to prompt for notification permission
OneSignal.shared.promptUserForPushNotificationPermission().then((accepted) {
    print("Accepted permission: $accepted");
});
window.plugins.OneSignal.setAppId("YOUR_ONESIGNAL_APP_ID");

iOS Push Prompting

iOS Apps have a native Alert Prompt that must be displayed and the user must authorize permission for your app to send them push notifications. iOS also supports Provisional Push Notifications.

You can display this Alert using the OneSignal SDK in 2 ways:

OneSignal.promptForPushNotifications(userResponse: { accepted in
  print("User accepted notifications: \(accepted)")
})
[OneSignal promptForPushNotificationsWithUserResponse:^(BOOL accepted) {
  NSLog(@"User accepted notifications: %d", accepted);
}];
var response = await OneSignal.Default.PromptForPushNotificationsWithUserResponse();
if (response == NotificationPermission.Authorized) {
    // user accepted
}
OneSignal.promptForPushNotificationsWithUserResponse(response => {
  console.log("Prompt response:", response);
});
OneSignal.shared.promptUserForPushNotificationPermission().then((accepted) {
    print("Accepted permission: $accepted");
});
OneSignal.promptForPushNotificationsWithUserResponse(function(accepted) {
    console.log("User accepted notifications: " + accepted);
});
window.plugins.OneSignal.promptForPushNotificationsWithUserResponse(function(accepted) {
    console.log("User accepted notifications: " + accepted);
});

External User Ids

OneSignal creates and stores device & channel level data under a unique OneSignal Id called the player_id. A single user can have multiple player_id records based on how many devices, email addresses, and phone numbers they use to interact with your app/site.

You can combine player_id records in OneSignal under a unique User Id called the external_user_id.

See the External User Ids guide for more details.

If you have a backend server, we strongly recommend using Identity Verification with your users. Your backend can generate an identifier authentication token and send it to your site.

The OneSignal SDK setExternalUserId method should be called when the user logs into the app/site and within the callback of the setEmail and setSMSNumber methods to link the records together.

let externalUserId = "123456789"; // You will supply the external user id to the OneSignal SDK

OneSignal.push(function() {
  OneSignal.setExternalUserId(externalUserId);
});
String externalUserId = "123456789"; // You will supply the external user id to the OneSignal SDK

// Setting External User Id with Callback Available in SDK Version 4.0.0+
OneSignal.setExternalUserId(externalUserId, new OneSignal.OSExternalUserIdUpdateCompletionHandler() {
    @Override
    public void onSuccess(JSONObject results) {
        try {
            if (results.has("push") && results.getJSONObject("push").has("success")) {
                boolean isPushSuccess = results.getJSONObject("push").getBoolean("success");
                OneSignal.onesignalLog(OneSignal.LOG_LEVEL.VERBOSE, "Set external user id for push status: " + isPushSuccess);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }

        try {
            if (results.has("email") && results.getJSONObject("email").has("success")) {
                boolean isEmailSuccess = results.getJSONObject("email").getBoolean("success");
                OneSignal.onesignalLog(OneSignal.LOG_LEVEL.VERBOSE, "Set external user id for email status: " + isEmailSuccess);
            }
        } catch (JSONException e) {

🚧

Warning - Android SDK Data Synchronization

The OneSignal Android SDKs leverage cacheing on external_user_id and Data Tags.

If setting external_user_id through the Edit device API Endpoint, then use the same endpoint to remove the external_user_id upon the user logging out of the app.

The removeExternalUserId method will not work unless the external_user_id is set first with the setExternalUserId method on Android.

This is only applicable on the OneSignal Android Mobile App SDKs.


Tags

Data Tags are custom key : value pairs of string or number data you set on users based on events or user data of your choosing. See Data Tags Overview for more details on what tags are used for.

See Data Tag Implementation for SDK Method details.


User Data

Methods to get the OneSignal Player ID, subscription status, prompt status and push token.

Use addPermissionObserver or addSubscriptionObserver to react to changes. For example, update your server when the user becomes subscribed or unsubscribed, and to get the OneSignal Player Id.

If you need to store the OneSignal Player Id within your backend, you can make a REST API call directly from the observer's callback. The OneSignal observer fires only when there is a change (including not firing even if the app has been restarted). This helps ensure you are not making unnecessary network calls to your backend on each app restart if nothing changed.

Getting User Properties

🚧

getDeviceState()

If getDeviceState() is called too early it will be null or no available. Use to load your UI to the correct state. Such as showing a toggle button to enable notifications.

Notification Permission Statuses

Name

Status

0 - Not Determined

The user hasn't yet made a choice about whether the app is allowed to schedule notifications.

1 - Denied

The application is not authorized to post user notifications.

2 - Authorized

The application is authorized to post user notifications.

3 - Provisional

The application is provisionally authorized to post noninterruptive user notifications. See iOS Customizations

4 - Ephemeral

For App Clips. The app is authorized to schedule or receive notifications for a limited amount of time.

User Data Change Events

Handling Notification Permission Changes

The onOSPermissionChanged method will be fired on the passed-in object when a notification permission setting changes.

This includes the following events:

  • Notification permission prompt shown (iOS)
  • The user accepting or declining the permission prompt (iOS)
  • Enabling or disabling notifications for your app in the App Settings and after returning to your app

Instance is given to your onOSPermissionChanged method, which provides what the value was ("from") and what the value is now ("to").

Any object implementing the OSPermissionObserver and/or the OSSubscriptionObserver protocols can be added as an observer. You can call removePermissionObserver to remove any existing listeners.

OneSignal uses a weak reference to the observer to prevent leaks.

public class MainActivity extends Activity implements OSPermissionObserver {
  protected void onCreate(Bundle savedInstanceState) {
    OneSignal.addPermissionObserver(this);
  }
  
  public void onOSPermissionChanged(OSPermissionStateChanges stateChanges) {
    if (stateChanges.getFrom().getEnabled() &&
        !stateChanges.getTo().getEnabled()) {
         new AlertDialog.Builder(this)
             .setMessage("Notifications Disabled!")
             .show();
      }
   
      Log.i("Debug", "onOSPermissionChanged: " + stateChanges);

Handling Subscription State Changes

The onOSSubscriptionChanged method will be fired on the passed-in object when a notification subscription property changes.

This includes the following events:

  • Getting a push token from Google or Apple
  • Getting a player/user id from OneSignal
  • OneSignal.disablePush is called
  • User disables or enables notifications

The instance is given to your onOSSubscriptionChanged method which provides what the value was ("from") and what the value is now ("to").

Any object implementing the OSPermissionObserver and/or the OSSubscriptionObserver protocols can be added as an observer. You can call removePermissionObserver to remove any existing listeners.

OneSignal uses a weak reference to the observer to prevent leaks.

public class MainActivity extends Activity implements OSSubscriptionObserver {
  protected void onCreate(Bundle savedInstanceState) {
    OneSignal.addSubscriptionObserver(this);
  }
  
  public void onOSSubscriptionChanged(OSSubscriptionStateChanges stateChanges) {
    if (!stateChanges.getFrom().getSubscribed() &&
        stateChanges.getTo().getSubscribed()) {
         new AlertDialog.Builder(this)
             .setMessage("You've successfully subscribed to push notifications!")
             .show();
        // get player ID
        stateChanges.getTo().getUserId();
      }
   
      Log.i("Debug", "onOSSubscriptionChanged: " + stateChanges);
  }
}

setLanguage Method

Language is detected and set automatically through the OneSignal SDK based on the device settings. This method allows you to change that language by passing in the 2-character, lowercase language code. See Supported Languages.

//Requires SDK 3.16.0+
OneSignal.setLanguage("es");
//Requires SDK 3.6.0+
OneSignal.setLanguage("es")
//Requires SDK 3.6.0+
[OneSignal setLanguage:@"es"];
OneSignal.Default.SetLanguage("es");
//Requires SDK 4.2.0+
OneSignal.setLanguage("es");
//Requires SDK 3.2.0+
OneSignal.setLanguage("es");

Privacy

setRequiresUserPrivacyConsent Method

For GDPR users, your application should call this method before initialization of the SDK.

If you pass in true, your application will need to call provideConsent(true) before the OneSignal SDK gets fully initialized. Until this happens, you can continue to call methods (such as sendTags()), but nothing will happen.

OneSignal.setRequiresUserPrivacyConsent(true);
//to require the user's consent before the SDK initializes
OneSignal.setRequiresUserPrivacyConsent(true);
//to require the user's consent before the SDK initializes
[OneSignal setRequiresUserPrivacyConsent:true];
OneSignal.Default.RequiresPrivacyConsent = true; // before init
// Will delay initialization of the SDK until the user provides consent
OneSignal.setRequiresUserPrivacyConsent(true);
await OneSignal.shared.setRequiresUserPrivacyConsent(true);
//will delay initialization of the SDK until the user provides consent
// Ionic 5 Capacitor may need to use (window as any).plugins.OneSignal
window.plugins.OneSignal.setRequiresUserPrivacyConsent(true);
//will delay initialization of the SDK
//make sure to call before init()
OneSignal.SetRequiresUserPrivacyConsent(true);

Consent Granted

If your application is set to require the user's privacy consent, you can provide this consent using this method. Until you call provideUserConsent(true), the SDK will not fully initialize, and will not send any data to OneSignal.

public void onUserTappedProvidePrivacyConsent(View v) {
  //will initialize the OneSignal SDK and enable push notifications
  OneSignal.provideUserConsent(true);
}
@IBAction func userTappedProvideConsentButton(_ sender : UIButton) {
  //this will complete the initialization of the SDK
    OneSignal.consentGranted(true); 
}
- (IBAction)setEmailButtonPressed:(UIButton *)sender {
  //this will complete the initialization of the SDK
  [OneSignal consentGranted:true];
}
OneSignal.Default.PrivacyConsent = true;

if (OneSignal.Default.PrivacyConsent) {
    // user provided consent
}
function userTappedProvideConsentButton() {
  // Will initialize the SDK and register for push notifications
  OneSignal.provideUserConsent(true);
}
// the SDK will now initialize
await OneSignal.shared.consentGranted(true);
// Ionic 5 Capacitor may need to use (window as any).plugins.OneSignal
window.plugins.OneSignal.userProvidedPrivacyConsent((providedConsent) => {
  //if providedConsent == true, it means the SDK has been initialized and can be used
});
PrivacyConsentButton.TouchUpInside += delegate
{
  //the SDK will now be initialized
    OneSignal.UserDidProvidePrivacyConsent(true);
};

Location Data

setLocationShared Method

Disable or enable location collection (defaults to enabled if your app has location permission).

Note: This method must be called before OneSignal initWithLaunchOptions on iOS.

OneSignal.setLocationShared(false);
OneSignal.setLocationShared(false)
[OneSignal setLocationShared:false];
OneSignal.Default.ShareLocation = true;
OneSignal.setLocationShared(false);
await OneSignal.shared.setLocationShared(false);
// Ionic 5 Capacitor may need to use (window as any).plugins.OneSignal
window.plugins.OneSignal.setLocationShared(false)
OneSignal.SetLocationShared(false);
//Our Web SDK does not track location, you can setup the browser to track this and tag the user with the latitutde and longitude

isLocationShared Method

Return a boolean that indicates location shared state (defaults to true if your app has location permission).

boolean locationShared = OneSignal.isLocationShared();
let locationShared = OneSignal.isLocationShared()
BOOL locationShared = [OneSignal isLocationShared];
var locationShared = OneSignal.Default.ShareLocation;
// Ionic 5 Capacitor may need to use (window as any).plugins.OneSignal
window.plugins.OneSignal.isLocationShared(function(shared) {
});

promptLocation Method

Recommended: use OneSignal's In-App Message Soft-Prompt before displaying the Native Alert. Details: Location Opt-In Prompt.

Prompts the user for location permissions to allow geotagging from the OneSignal dashboard. This lets you send notifications based on the device's location. See Location-Triggered Notifications for more details.

Make sure you add location permissions in your AndroidManifest.xml and/or info.plist.

// Make sure you add one of the following permissions
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
//These are examples of how you may setup the app. See Apple's Guide on this: https://developer.apple.com/documentation/corelocation/requesting_authorization_for_location_services
// Example plist image: https://i.imgur.com/OZDQpyQ.png

<key>NSLocationUsageDescription</key>
  <string>Your message goes here</string>
<key>NSLocationWhenInUseUsageDescription</key>
    <string>Your message goes here</string>  
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
  <string>Your message goes here</string>
<key>NSLocationAlwaysUsageDescription</key>
    <string>Your message goes here</string>
<key>UIBackgroundModes</key>
    <array>
        <string>location</string>
        <string>remote-notification</string>
    </array>

On Android, you need to add the location dependency

dependencies {
  ...
  implementation 'com.google.android.gms:play-services-location:YOUR_PLAY_SERVICES_VERSION'
}

Finally, don't forget to call the prompt location method

OneSignal.promptLocation();
OneSignal.promptLocation()
[OneSignal promptLocation];
OneSignal.Default.PromptLocation();
// Calling promptLocation
OneSignal.promptLocation();
await OneSignal.shared.promptLocationPermission();
// Ionic 5 Capacitor may need to use (window as any).plugins.OneSignal
window.plugins.OneSignal.promptLocation();
OneSignal.Current.PromptLocation();

Push Notifications

Notification Events & Payload

OneSignal Provides methods for handling notifications received and clicked/opened events. Details and discussion on implementation and Notification Payload in SDK Notification Event Handlers.

To send notifications to users, we recommend using the Create notification REST API docs, or Messages Dashboard.

postNotification Method

Recommended for scheduling notifications in the future to the current user.

🚧

User Targeting Warning

You can only use include_player_ids as a targeting parameter from your app. Other target options such as tags and included_segments require your OneSignal App REST API key which can only be used from your server.

See the Create notification REST API POST call for a list of all possible options.

clearOneSignalNotifications Method

Android only. iOS provides a standard way to clear notifications by clearing badge count. There is no specific OneSignal API call for clearing notifications.

OneSignal.clearOneSignalNotifications();
OneSignal.Default.ClearOneSignalNotifications();
OneSignal.clearOneSignalNotifications();
//Currently not available
// Ionic 5 Capacitor may need to use (window as any).plugins.OneSignal
OneSignal.clearOneSignalNotifications();
OneSignal.Current.ClearOneSignalNotifications();
OneSignal.ClearAllNotifications()
//Not available

disablePush Method

The user must first subscribe through the native prompt or app settings. It does not officially subscribe or unsubscribe them from the app settings, it unsubscribes them from receiving push from OneSignal.
You can only call this method with true to opt out users from receiving notifications through OneSignal. You can pass false later to opt users back into notifications.

// Android SDK version 4.x.x
OneSignal.disablePush(true);

//Android SDK version 3.x.x
OneSignal.setSubscription(false);
// iOS SDK 3.x.x use
OneSignal.disablePush(true)

// iOS SDK 2.x.x use
OneSignal.setSubscription(false)
// iOS SDK 3.x.x use
[OneSignal disablePush:true];

// iOS SDK 2.x.x use
[OneSignal setSubscription:false];
OneSignal.Default.PushEnabled = false;
// RN SDK 4.x.x use
OneSignal.disablePush(true);

// RN SDK 3.x.x use
OneSignal.setSubscription(false);
// Flutter SDK 3.x.x use
await OneSignal.shared.disablePush(true);

// Flutter SDK 2.x.x use
await OneSignal.shared.setSubscription(false);
// Ionic 5 Capacitor may need to use (window as any).plugins.OneSignal
window.plugins.OneSignal.disablePush(false);
OneSignal.SetSubscription(false);
OneSignal.SetSubscription(false)
OneSignal.setSubscription(false);

EnableVibrate & EnableSound Methods

These methods were designed for Android but stopped working in Android 8+ due to a breaking change. To customize going forward, use Android Notification Categories (Channels).

unsubscribeWhenNotificationsAreDisabled Method

Only available on Android Native SDK. If notifications are disabled for your app, unsubscribe the user from OneSignal.

Use case: if notifications are disabled for your app and you still want background notifications to work, pass in false.

OneSignal.unsubscribeWhenNotificationsAreDisabled(false);
REMOVED - Stopped working in Android 8+ due to a breaking change. 
To customize going forward, use Notification Categories (Channels).

setLaunchURLsInApp Method (iOS)

This method can be used to set if launch URLs should be opened in safari or within the application. Set to true to launch all notifications with a URL in the app instead of the default web browser. Make sure to call setLaunchURLsInApp before the setAppId call.

OneSignal.Default.SetLaunchURLsInApp(true); // before Initialize

Parameter Type

Description

Bool

Boolean indicates if launch URLs should be opened in safari or within the application.


In-App Messages

In-App Messages do not require any code to get started, but if you would like to setup custom triggers to display the In-App Message under certain conditions and track IAM lifecycle events, we have SDK methods for you!

See our In-App Message SDK Methods for details.


Email

OneSignal's Mobile and Web SDKs provide methods for collecting emails, logging out emails, and tracking email subscription changes.

See the Email SDK Methods guide for more details.

If you have a backend server, we strongly recommend using Identity Verification with your users. Your backend can generate an Email authentication token and send it to your app.


SMS

OneSignal's Mobile and Web SDKs provide methods for collecting phone numbers, logging out phone numbers, and tracking sms subscription.

See the SMS SDK Methods guide for more details.

If you have a backend server, we strongly recommend using Identity Verification with your users. Your backend can generate an SMS authentication token and send it to your app.
