For push notification in blackberry, i got application id from rim. It will valid only 4 months. For getting permanent application id what i do.
You have to contact the person who gave you the push credentials. And request them to upgrade your EVAL credentials to Production push credentials.

I have integrated FCM in my IOS application. I have added both Development and Production push certificate in the Firebase console. I have been developing the application for the last 1 year. Everything was working fine before 2/3 months back.
I installed the application in the device and received a token from firebase and when I tried to send the notification to this token. It is showing as InvalidRegistration/Not Registered. When I run my application, say for 3/4 times, I will get new push tokens which are also invalid ones and at last, I will get the valid push token.
I updated the Firebase, regenerated new push certificates but still the same issue. Is there anything I need to do in order​ to receive the valid push token and hence the notifications.
Please suggest.
You have two Certificates types, the old .p12 and the new p8 certificate.
The .p12 certificate is only valid for 1 year, the p8 a lot longer.
When you create your certificates, make sure that you upload your certificates to apple and Firebase.
I recommend to use the new p8 certificate.
I ran into a problem while integration "Registering a Device to Receive Push Notifications for a Pass" web service on my server for Apple Passes.
Link Below: https://developer.apple.com/library/content/documentation/PassKit/Reference/PassKit_WebService/WebService.html.
I've followed the following steps:
Able to successfully generate and distribute Apple Pass on iPhones through a downloadable link.
Once pass is downloaded, I'm adding that pass to Apple Wallet. While adding, Registration web service is called which must send my server a Device ID and Push Token, but I am getting these two parameters as nil.
However when I'm hitting the same URL on AdvanceRestClient(with dummy Device ID and Token), I do get the callback.
I wanted to know why I'm not getting device Id and Push token from iPhone??
I've successfully setup my hub to use an SSL certificate per app, but I'd really like to move to the token-based APNs Auth Key approach. I configured my hub with I believe all the right information from the p8 file. For Key ID, I put in the 10-character value from when key was generated. For App ID, I put in my Team ID. For Token, I put in the private key value from the p8 file.
Has anyone had any success with this? Here's what happens when I attempt to send a test message:
When set to sandbox and I do a test send to my device, I get a failed outcome of "The Push Notification System rejected the request because of an invalid credential".
When set to production and I do a test send to my device, I get a failed outcome of "The Token obtained from the Token Provider is invalid"
For production, I think that is because I'm sending to a local app build outside of TestFlight/app store, so it is expecting the "development" or sandbox aps-environment.
Not sure what other troubleshooting I can do.
TIA,
I figured out what was happening for me.
The App Name field in the Azure Portal is critical to how the message gets delivered. Even though an APNs Auth Key can be used across multiple apps, the notification still must set the topic to be for that particular app. It seems like Azure Notification Hubs take the App Name field and put it into the apns-topic. Once I had that set to my app identifier, it worked as expected.
Also as an FYI, here is the link to the official documentation

I am developing an iOS application with notification by Google Cloud Messaging Service.(GCM).
I have been made android applications with GCM so am willing to make an iOS app of GCM notification(Not using APNS).
Questions came out about APNS token and GCM Registration ID.
Question #1
every time iOS App launches it checks if APNS token changes or updates when it changed. when APNS changes, does iOS app request 'new GCM Registration ID'?
Question #2
If Question #1 is right, should I just send new GCM Registration ID to my push server?
Question #3
Does GCM Registration ID change even if APNS token has not been updated at all?
Question #1 every time iOS App launches it checks if APNS token changes or updates when it changed. when APNS changes, does iOS app request 'new GCM Registration ID'?
Based from this documentation, when GCM registration token refresh is initiated from server side, the client app must handle a tokenRefreshed message with the GCM registration client/server handshake.
Question #2 If Question #1 is right, should I just send new GCM Registration ID to my push server?
Device tokens can change, so your app needs to reregister every time it is launched and pass the received token back to your server. Check this related SO question.
Question #3 Does GCM Registration ID change even if APNS token has not been updated at all?
According to this SO question, the registration ID will not change when token hs not been updated. "The only known cause for registration ID change is the old bug of apps getting unregistered automatically if they receive a message while getting upgraded. Until this bug is fixed apps still need to call register() after upgrade, and so far the registration ID may change in this case. Calling unregister() explicitly usually changes the registration ID too."
We have a server to send notifications to our users on iOS and Android. Android works fine.
The problem is, when an user uninstalls and reinstalls our app. The app then requests a new push ID from GCM with its APNS ID(which is still the same) and sends us the new ID. Now we have 2 records to send notifications to. It looks like GCM just maps its generated ID to APNS ID in a simple N:1 relation.
If we had the same situation in Android and we now send our notifications to GCM, it would send the canonical ID in the first response, so we can react to that to not send a second notification. But with iOS it does not. The response looks like a normal, complete, successful request.
Did we miss something or didn't GCM implement canonical ids for iOS? I couldn't find any information regarding this problem.
A registration token is per device per installation.
Every time you uninstall and reinstall your app (either iOS or android), GCM will give you a new registration token.
It is a similar concept to Canonical IDs. If you get a Canonical ID, then you need to replace your old registration token in your server with the newly returned Canonical ID, as eventually the old registration token will stop working.
So, if you get a new registration token back when you uninstall and reinstall your iOS app (or Android app), you can simply compare the newly returned token with the old one. If the new token is different from the old token, then you can just replace the old one with the new one in your server so that you dont need to maintain 2 tokens in your server.
