Push notification appears after one user messages another user using firebase and xcode - xcode

If I were to make a messaging app which would involve a user recieving a notification after being messaged by another user, how could i go about setting up the notifications in such a way where they are sent after the message is sent by the user who sent it. If someone could point me in the right direction that would be awesome thank you.
P.S. I am using cloud messaging

How to make Slack app send a private message via an incoming webhook to someone specific?

I created a Slack app that sends a series of interactive messages to a channel. In my Slack API dashboard, I see that I can create and remove hooks. Right now the hook url that I have set up in my code is the one for the Slackbot channel.
But the problem is that such a message only gets sent to me.
I want to send the Slackbot messages to Alice in situation A, and to Bob in situation B. Not just to myself, the guy who configured the app.
What's the best way to do this?
I would suggest that you should not use hooks for this. A more sane way to do this right would be via chat.postMessage Web API method which is documented here!
This is because hooks are tied to specific conversations and that approach quickly hits a wall on what it can really achieve, especially messaging different people. Once you start using the web API it's pretty simple. Just ask for the scope during app installation (remember to add that scope in your dashboard), subscribe to the event in your API dashboard and then you are good to go.
Everytime you send a message via that method, Slack will send you a payload which you can use for testing and logging etc.
You can see all the different ways to message programmatically inside Slack here.

Laravel notification facebook driver get fb_messenger_user_id

I want to give users the ability to get notifications via the facebook messenger. However, I don't really know how to get the fb_messenger_user_id from a user.
I can get a personalized ID for the chat if a user starts chatting with my bot, but with this, I can't really verify which user that is. Is there something I've overseen? Something like a button similar to the "login with facebook" button?
Also, as far as I understand the docs, I am only allowed to send messages in a time frame of 24h after the last message from the user.
Can someone tell me how to use the facebook notifications properly?
As a side note: I am planning to implement botman into my existing app. I don't know how much this affects the notifications.

how to detect received push notification when app is closed

Is there anybody knows that if I received a push notification when my app is fully closed, but then I go back to open the app how can I detect this received notification and make certain changes pertain to this notification?
Thanks very much in advance.
I found out a way:
Just detect the Badge numbers, and set it as a user default in app delegate.
In other view controllers, you can perform stuffs depends on the badge numbers, which you can track from NSUserDefault.

Use of Raw Notifications in WP7

I read the implementation of three types of notifications possible in WP7 app - Tile, Toast and Raw Notifications. I understand the use of Tile and Toast Notifications but I fail to understand how a Raw notification will be used in real world application. Can someone please help me understand.
If someone can help me understand the implementation wrt. an existing application like KIK messenger or WhatsApp Messenger, it will be great!
Regards,
Bhavik.
Raw notifications provides the ability for your application service to push data to the application while it is in the foreground without the need for your application to poll the appplication service.
For instance, meaning if you have the Messages application open, and you get a new Message, it'll show a notification (toast), without the Messages application having to poll for it.
