your_auth_key - What is it?

[liorphp]

$config = new Config('your_application_id', 'your_application_auth_key', 'your_auth_key');

What is the third parameter (your_auth_key)? Where should I get it from?

You can find it in Account & API Keys section in app.onesignal.com.

Click on the account menu in the right side of the header -> click Account & API Keys -> scroll down to User Auth Key.

Basically it allows you to manage your apps via API, while with the app_id and app_key you can only manage only provided application devices and notifications.

Also note that it's an optional configuration parameter and you can leave it out as null if you don't need to access to apps api.
