Ionic 3 app notificate user


Hello everyone,

I develop a mobile application with Ionic Framework who consist to build relationship between many users. In this application i want to send notification to specific user when another user post new messages or new comments like Facebook, Twitter or Instagram.

Also, i want to send notification to all of my users when one of them post new article.

Can you help me to solve this issue ?

Best Regards,



You can use to send push notifications.


Hello @leonardoss thank you for your reply, i explore and with this service, all messages can be send using onesignal dashboard and not in my application.

For example, if user X send me message, i want to have notification about this message without go to onesignal dashboard.


No, you are wrong, OneSignal have an Rest API, you need to: When user click in button, you will call this api to send notification with a simple http request. You need to read the docs again :wink:

OneSignal’s server API can be used to:

  • Programmatically deliver notifications from your server or device to another device *

  • Add, update, and fetch data for your users without using our mobile or web SDKs.

  • Export User or Notification data from OneSignal.


Really ?? :grinning:

I need to read One Signal Api documentation for more details. Thank your for your advice, it’s very helpfull


No problems dude, just read about this api and you will be able to send a notification between devices, if you have a server with some backend code, consider to call onesignal api from your server and not directly from the app. I think you already have an server to handle app data and user login and etc… In this backend, create a new method that receives userId and calls OneSignal to send it to user you want.


Hello @leonardoss,

Thank you.
