The ontokenrefresh will be called as they're regenerated, but they're expected to be pretty long lived. I also need to know the effective lifetime of Firebase tokens. I cannot use the provided answer of "pretty long lived. My use case: User installs app which provides a local service. App saves its FCM token to backend's database. Service is not yet available in user's area so app is unusable.

Weeks or months later, when service is launched in their area, backend gets the FCM token from the database and sends a notification to the user informing them. The user taps on the notification and opens the app. Or the user sees the badge on the app and opens it. I need to know if the user will receive a notification using an FCM token that is weeks or months old and an app that has not been opened in weeks or months.

I need to know the answer for both Android and iOS.

Tokens can be refreshed at any time, so it isn't safe to guess at their lifetime. Instead, use the onTokenRefresh callback so that you are notified when a new token is created.

New issue. Jump to bottom. When is the expiry of a token generated using FCM? Copy link Quote reply. This is not an issue.

I don't see any documentation regarding the expiry of an FCM token anywhere. I am getting the token like this. This comment has been minimized. Sign in to view. But don't clarify about time expiration. The token can expire after determined time?

Let me rephrase the same question that has been asked by almost everyone on this thread and did not yet get an answer into a slightly different form: Can you provide clear documentation as to whether Firebase might invalidate a token on their backend, and if so, when, or whether it only happens?

Or is it always client-managed? Is there a way to test whether a token is still valid? What are recommended approaches to token lifetime management? How to best deal with that, without ending up storing tons of invalidated registration tokens?The quickstart example provides sample code for both languages. Relevant areas of the guides provide code examples, both with and without method swizzling enabled.

This section covers tasks you may have completed if you have already enabled other Firebase features for your app. If you don't already have an Xcode project and just want to try out a Firebase product, you can download one of our quickstart samples.

The code snippet below is an example how I can get the FCM token, but since this is depreciated, what is the recommended way? I have seen android specific code in Java that looks similar to this as the "new way", but I can't seem to translate this into Xamarin.

But it's the Preview version, so it's maybe not very stable. As "FirebaseInstanceId. Token" became obsolete, for getting the token you can use the following: 1. Implement in your class Android. IOnSuccessListener - if you also extend Java. GetMethod "getToken". Invoke result. It works perfectly. But does it just ignore or bypass a warning? I found another way but since this is not documented, probably it is just luck and it doesnt' work :P.

Anyway, the problem is that OnNewToken is not called on each app start and sometimes you loose the token and want to know what the token is at the moment. At this point it is easy! Just port it to Xamarin, use the c format and The sender ID is the number in your google-services. Or you can find it in the dashboard, under settings cloud messaging:. Now, you can put the code somewhere in your code.

For example in the FirebaseService.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

From the documentation, it says: A previously valid registration token can be unregistered for a variety of reasons, including:. We didn't notice issue until recently. Previously, the token refresh seems to happen once a month or so. Now it happened really frequently. What changes? The token gets invalidated really quickly. The user shouldn't be expected to open the app everyday.

From my logs, it got invalidated after 2 days. Can you share your project ID? This looks like a backend issue and may require looking at your Firebase project information.

Instead of emailing me directly, you should file a support ticket so we can keep all your debugging-related nonpublic information in one place the ticket can link to this GH issue.

Apologies for the misdirection, I realize this is really obtuse after asking you to file a separate issue. Thank you! This is really bad. I sent it out a week ago, but no update there.

I also tried to update to the latest SDK and the token still gets invalidated after 3 days without opening the app after the token was generated. Looks like your tokens are being replaced, while still valid, by new tokens. Can you send a currently valid token? This way we can check what's causing it to be refreshed while still valid.

Not sure yet. It looks like your app is sending up frequent requests to register a new token, though this may not be the root cause of the issue since your app has always been doing this and this has only been an issue recently. I tried calling this multiple times, but the delegate returns the same token.

If the app is open and new token is generated, It will send the new token to the backend, so it's not an issue. The app is not active when the token gets invalidated, so there shouldn't be any request made. Maybe I can try debug it on my end too.

Should I? From the docs, "Either at startup, or at the desired point in your application flow, register your app for remote notifications". Let me check and I'll get back to you on the second question. Looks like there's nothing wrong going on in your code. Are you able to reproduce this with the Messaging quickstart repo?

Can you tell me what triggers the token to be refreshed?Method swizzling available with FCM simplifies your client code. FCM swizzling affects how you handle the default registration token, and how you handle downstream message callbacks. Where applicable, this guide provides migration examples both with and without method swizzling enabled. In the Firebase consoleselect Add project. A new GoogleServices-info. Select Continue and follow the detailed instructions for creating an xcworkspace file for your app and connecting to Firebase on startup.

FCM is initialized as part of overall Firebase app initialization. You must follow different steps to migrate registration token-related code depending on whether or not you disable swizzling. The token refresh notification is invoked whenever the SDK generates a token, including the first time.

With FCM, client apps listen for the relevant notifications by adding observers for each of them. Note that the new FCM version of gcm-http.

Notification messages contain a predefined set of user-visible keys.

Data messages, by contrast, contain only your user-defined custom key-value pairs. Notification messages can contain an optional data payload. Maximum payload for both message types is 4KB, except when sending messages from the Firebase console, which enforces a character limit. Use scenario How to send Notification message FCM automatically displays the message to end-user devices on behalf of the client app. Notification messages have a predefined set of user-visible keys and an optional data payload of custom key-value pairs.

May have optional data payload. Always collapsible. Add optional data payload by providing Custom data. Data message Client app is responsible for processing data messages. Data messages have only custom key-value pairs. Use notification messages when you want FCM to handle displaying a notification on your client app's behalf.

Use data messages when you want to process the messages on your client app. FCM can send a notification message including an optional data payload.

In such cases, FCM handles displaying the notification payload, and the client app handles the data payload. For testing or for marketing and user re-engagement, you can send notification messages using the Firebase console.

To programmatically send notification messages using the Admin SDK or the FCM protocols, set the notification key with the necessary predefined set of key-value options for the user-visible part of the notification message. The user can expect to see a message with the title "Portugal vs. Denmark" and the text "great match! Denmark", "body":"great match!

Notification messages are delivered to the notification tray when the app is in the background.You generate these tokens on your server, pass them back to a client device, and then use them to authenticate via the signInWithCustomToken method. To achieve this, you must create a server endpoint that accepts sign-in credentials—such as a username and password—and, if the credentials are valid, returns a custom JWT.

Once authenticated, this identity will be used when accessing other Firebase services, such as the Firebase Realtime Database and Cloud Storage. You can create a custom token with the Firebase Admin SDK, or you can use a third-party JWT library if your server is written in a language which Firebase does not natively support. Custom tokens are signed JWTs where the private key used for signing belongs to a Google service account. There are several ways to specify the Google service account that should be used by the Firebase Admin SDK for signing custom tokens:.

They can be downloaded from the Firebase Console. This method of initialization is suitable for a wide range of Admin SDK deployments. The main drawback of this approach is that it requires you to package a service account JSON file along with your code. Also note that the private key in a service account JSON file is sensitive information, and special care must be taken to keep it confidential. Specifically, refrain from adding service account JSON files to public version control.

If your code is deployed in an environment managed by Google, the Admin SDK can attempt to auto-discover a means to sign custom tokens:.

The App Identity service signs data using a service account provisioned for your app by Google App Engine. If your code is deployed in some other managed environment e. The discovered service account ID is then used in conjunction with the IAM service to sign tokens remotely.

If the Firebase Admin SDK has to discover a service account ID string, it does so when your code creates a custom token for the first time. The result is cached and reused for subsequent token signing operations. The auto-discovered service account ID is usually one of the default service accounts provided by the Google Cloud Platform:. Just like with explicitly specified service account IDs, auto-discoverd service account IDs must have the iam. You may have to use the IAM and admin section of the Google Cloud Platform Console to grant the default service accounts the necessary permissions.

See the troubleshooting section below for more details. To maintain consistency between various parts of your application, you can specify a service account ID whose keys will be used to sign tokens when running in a Google-managed environment. They uniquely identify service accounts in Firebase and Google Cloud Platform projects. Service account IDs are not sensitive information and therefore their exposure is inconsequential. However, to sign custom tokens with the specified service account, the Firebase Admin SDK must invoke a remote service.

At a minimum, you need to provide a uidwhich can be any string but should uniquely identify the user or device you are authenticating. These tokens expire after one hour. You can also optionally specify additional claims to be included in the custom token. After you create a custom token, you should send it to your client app.

The client app authenticates with the custom token by calling signInWithCustomToken :. If the authentication succeeds, your user will be now signed into your client app with the account specified by the uid included in the custom token.

If that account did not previously exist, a record for that user will be created. In this case, the uid will be the one that you specified when generating the custom token. If the custom token contains additional claims, they can be referenced off of the auth.

If your backend is in a language that doesn't have an official Firebase Admin SDK, you can still manually create custom tokens. First, find a third-party JWT library for your language. Here are some example implementations of how to create custom tokens in a variety of languages that the Firebase Admin SDK does not support:. Using php-jwt :. Using ruby-jwt :. After you create the custom token, send it to your client app to use to authenticate with Firebase.
