More details on your User Auth Key below.
Your OneSignal App ID or just App ID, is the main identifier we use to differentiate your app from all other OneSignal apps. You will use this in all your SDK initialization codes and API calls. The App ID should not be treated as private.
Do not share this key
Treat your REST API Key as though it is a password - do not add it to your app code or public repositories (e.g. github) and do not share it with anyone.
Your App Auth Key, which is your REST API key for app-specific operations (getting users of an app, modifying users, getting notifications, sending notifications) listed in the Keys & IDs section, add an HTTP header with the key
Authorization and the value
Basic REST_API_KEY, where you should replace
REST_API_KEY with your actual APP REST API key.
Visit Settings -> Keys & IDs.
On the right side where tip text is displayed, click "reset your API Key". It is above the icon that says "Read our documentation".
The keys for all your apps are also available all together within the Account section.
You may disable your app to prevent new and scheduled notifications from being delivered.
You will still receive new subscribers if you disable the app. You must remove or comment out the OneSignal code to stop new subscriptions.
Apps you manually disable can be instantly re-enabled at any time.
Your User Auth Key which can be found in Account manages operations outside of an app (e.g. creating an app). Click on the account dropdown on the top right of your dashboard and scroll down to the User Auth Key section. It is past the section that displays each of your app's auth keys.
