Hi there,

I have successfully setup my first _Discourse_ forum having force SSO login.

I would like to have this forum integrated in mobile app as well, for better impressions and was looking for Cloud Messaging options around. As Discourse has only push notifications, I have figured out the **webhook** way, which will send notifications to my external server, which will handle GCM/FCM calls.

It was successful with the integration, but I would like to prevent sending notifications to the same user who had posted/replied. I can identify the user if email address or SSO external ID is passing along with webhook requests (username trim from _@_!).

Can someone provide a solution to get posted user’s email/SSO external ID in webhook?

Thanks in advance.

I have a solution here, not straight forward, but I feel it should work.

**Step 1**

1. Create another webhook which will be triggered on _ **User Event** _
2. Disable _email editable_ option for users
3. When the webhook triggers, take user email address and update user’s forum ID in user database.

**Step 2**

1. When user login in the mobile application, get user’s FCM/GCM ID
2. Update FCM/GCM ID user database
3. When topic/post event trigerrs  
**a)** Send to all users through _topics_ subscription, mention user’s FCM/GCM ID in data payload and skip showing the notification to that user  
**OR**  
**b)** Get users who are eligible to get notifications (having mobile app) except the one who has posted/replied and send to others (This is not a scalable solution, I suppose)

Any other suggestions or straight forward methods/approach available?
