Finish and Save Your Settings

Be sure to Save your configuration at the bottom of the plugin once you've added these keys.

Step 5. Add your first user

Visit your website and you should see the OneSignal Slide and Subscription Bell on your site. You may need to clear any cache plugins you have and refresh the page.

Subscribe to push notifications and check your OneSignal Dashboard Audience > Users to see your user data.

Make sure push notifications are enabled in your device settings. Then head over to Messages > New Push to Send your first Push Notification from OneSignal.

Step 7. Send Push From Your WordPress Site

Notifications can be sent automatically when you publish a post from the WordPress "Posts" tab. You can send push anytime from the OneSignal.com Dashboard or API. See Sending Push Messages.

Simply create your post as usual and under "OneSignal Push Notifications" check Send notification on post publish.

If your post is a different post type, you might see "Send notification on forum publish". If you are updating instead of creating, you might see "Send notification on post update". Each of these options should successfully send a notification on the described action.

Welcome Notification

Welcome notifications are an optional way to thank users after subscribing to your site. Users will see a welcome notification as soon as they subscribe. You can edit or disable them in the Configure section of your plugin.
