apns | Golang package for sending Apple Push Notifications | Notification library

I am sending push notification using php code and ios didn't get notification so whats the exact issue i don't know please help.

When I try to put an array as a parameter for cloud functions. In my code, the array shows up correct, but in the logs for the cloud function it shows up as undefined.

Array Result: ["user1", "user2"]

Cloud Function:

I am having absolutely no luck getting push notifications to work in iOS in a Xamarin Forms project.

In AppDelegate.cs, I am calling the following in the FinishedLaunching override:

My app is implemented in React Native and is using Firebase for notifications. We have webhooks on the web app that are triggered on certain events. Those webhooks then send a request to the respective Firebase Cloud Function. With information from the request's header they get the topic they must send the notification to; from the request's body it gathers the information to be sent as data to the device. They are sent as data notifications only, the handler (using the React Native FCM API) then shows a local notification already translated with i18n using the react-native-push-notifications package. Everything works fine until I hit the weird situation described below.

Everything was doing alright both on Android and iOS until I launched the app on Test Flight for internal testing and then it stopped working after some time on iOS. Eventually, I noticed that when more than one iPhone subscribed to the same topic it eventually lead to inconsistencies in the delivery of the data notifications. The first iPhone to subscribe to the topic usually worked, the others didn't, the first one most of the time eventually stopped working as well or sometimes it just kept working while the others still didn't. I used the Firebase Console to send some test notification to the subscribed devices and it they actually received it. I then changed my Cloud Functions' code to avoid sending any data and just send some example body and title and it turns out the problem was here. As soon as I send something through the data field in the admin.messaging.Message object to be sent as argument to the admin.messaging().send method, they aren't received by the iPhone devices subscribed to the topic (or it's received by one or two max, the first ones to currently subscribe to the topic. But they usually stop receiving them after a while as well).

This is really really weird and being so inconsistent makes it practically impossible to debug with my current knowledge. Some things to keep in mind:

• All Android devices still receive the notifications without a problem
• I've watched the iPhone's console through Xcode to see if there was some error when processing the notification, in case they were actually getting the notification but they it failed before it was shown to the user. But nothing is logged by the SpringBoard process, making me conclude the notifications aren't actually getting to the device
• I've manually sent notifications with cURL to APNs (with this guide). They were received fine
• All notifications without data, regardless of the iOS specific apn headers, payload, etc, are received

What can be the cause of the problem? Or there's something in my code causing this strange behavior (which I doubt, since it works fine on Android and works fine in iOS as well on specific scenarios), there's some type of bug on Firebase's side causing some notifications to not be sent or, finally, there's some error on Apple's APNs side causing this. Highly doubt the last one, if the fault lays on any exterior factor it probably should be on Firebase's handling of topics.

Really would appreciate some help. Thanks in advance. Sorry If I didn't gave enough information, I actually never had the need to do a question on Stack Overflow. I'll leave below an example of a cloud function as well.

I am new to certificate generation. We have our app(Xamarin.Forms-iOS) in production already and planned for another production release this month end.

Provisional profile and distribution profile are expiring by May end. And APNS certificate is going to expire by June end.

Note: All the above certificates are generated from team-members's system (CSR).

Can I re-generate provisional profile and distribution certificate this month from my system and release build to production? Will that affect existing app or something?

And during June, if I regenerate APNS certificate from my system and upload it to azure hub. Will the production app continues to work fine (receive push notification)?

Is there any dependency between CSR or APNS dependency with other certificate?

Note: I will be re-generating certificates from my machine for the same bundle identifier.

When we are sending a FCM data message with the Firebase Admin SDK to an iOS device we are getting the following exception.

I am sending cloud-messages to my app but Firebase-CF-Reports tells me that they would not be received:

But I know for sure that some devices do receive them. e.g. my own. So something is going wrong here in the reports.

I read about this problem here and here but I already have an analytics-label that I send with my cloud-message.

This is how I sent my notifications with java-admin-sdk:

I have a project which use VoiP pushes for calling and APNS pushes for simple notifications. APNS push comes, but VoiP doesn't come. When server tries to send me VoiP push by my VoiP token server throws exception "Invalid Token". Please, see my solution and let me know what I do worst.

I created two certificates (APNS and VoiP)

I added certificate to identify, but I can add just APNS

Next, I generated p12 keys and send to server for using them.

In UIApplicationDelegate I retrieve APNS token and send to server

I have set up the Ionic/Capacitor app to receive push notifications following the capacitor tutorial,

I went through all the tutorial successfully and I receive test notifications sent from FCM both in foreground and background

I can successfully register to a topic I can receive notifications sent to the topic I can receive notifications sent to the token (test mode)

Now I'm trying to send notifications from a different device, I just created a two test button to send notification in multicast to an array of tokens and another button to send notification to a given topic

In both cases from my device I receive the notifications in foreground, but not in background

I believe is something wrong with the format I'm using to send the notifications that is not correct in case of background (I can receive those from the FCM test tool)
