I am building a Windows Phone 8.1 application and want to add push notifications from Windows Azure. I am creating the channel by using CreatePushNotificationChannelForApplicationAsync, after which I take the resulting URI and store it in the Azure database. When trying to send a push notification by using push.wns.sendToastText01, I get the following error in the Azure logs:
Error in script '/table/Message.insert.js'. Error: 400 - An invalid tag 'https://db3.notify.windows.com/?token=AwYAAAC3tTi3W5ItZ0hWdZ3FLmELt%2flHcwpsM...' was supplied. Valid tag characters are alphanumeric, _, #, -, ., : and #.
I noticed that the channel URI contains the '%' which does not appear among the valid characters, yet that is the URI that gets generated in the client application. Am I using a wrong method for sending push notifications or is there something else I am missing?
Edit: I am using Node.js for backend in Azure.
request.execute({
success: function() {
push.wns.sendToastText01(channelUri, {
text1: "Google Plus Friend Tracker",
text2: item.content,
param: '/ChatPage.xaml?friendGoogleId=' + item.author_id
})
}
});
Looking at the wns object documentation, the first parameter would be the tags that you are sending to. Since you're providing a channel in the code above, you are getting the error specified.
The backend does not need to provide the channel URI, as this was associated with the Notification Hub via the client-side registration action. If you are broadcasting the message, you would just provide null as the tag value. Otherwise, you can use the tags that were specified when you registered the channel URI.
For more about the process, see the "Get started with push" tutorial. There is also an example of using a tag (user ID) in the "Send push notifications to authenticated users" tutorial. For more on tags in general, the Notification Hubs breaking news tutorial is also good.

I hope you are doing fine :)
I have the following problem/problems.
I have created a dummy (robot) user. In Azure AD there is an App Registration with some Power BI delegated permission services.
I want to automate the deletion of a push dataset via a HTTP request.
For this, I need to authenticate against that App Registration from Azure AD. With postman, everything worked perfectly, I got the token as a response.
Then, I tried to make the same request using the HTTP connector in PowerAutomate.
I get the following error
{"error":"invalid_request","error_description":"AADSTS900144: The request body must contain the following parameter: 'grant_type'.\r\nTrace ID: e6d68953-ce1c-4217-856c-ae3aada82e00\r\nCorrelation ID: f50db4d9-d5bb-4396-af11-214717721f43\r\nTimestamp: 2022-10-26 19:12:48Z","error_codes":[900144],"timestamp":"2022-10-26 19:12:48Z","trace_id":"e6d68953-ce1c-4217-856c-ae3aada82e00","correlation_id":"f50db4d9-d5bb-4396-af11-214717721f43","error_uri":"https://login.microsoftonline.com/error?code=900144"}
The connector looks like this->
I have tried other ways as well.
The following error ->
{"error":"invalid_grant","error_description":"AADSTS50126: Error validating credentials due to invalid username or password.\r\nTrace ID: fec65949-0701-4727-af3b-2c2b8eb73a00\r\nCorrelation ID: 42c6c04b-98be-477d-8d36-52a01a473a40\r\nTimestamp: 2022-10-26 19:23:50Z","error_codes":[50126],"timestamp":"2022-10-26 19:23:50Z","trace_id":"fec65949-0701-4727-af3b-2c2b8eb73a00","correlation_id":"42c6c04b-98be-477d-8d36-52a01a473a40","error_uri":"https://login.microsoftonline.com/error?code=50126"}
I get from the the next HTTP connector inputs. I tried creating a query out of the previous json. It says the username or password are invalid but I logged in successfully for a number of times with those exact credentials. That I am sure of.
The dummy inputs in the picture are used to avoid the real ids, username and password.
This worked for me ...
Add a header setting Content-Type to application/x-www-form-urlencoded and add the URL form encoded content string like thus ...
client_id=<CLIENT_ID>c&grant_type=password&username=<USERNAME>&password=<PASSWORD>&scope=User.read
If you're using the password grant type approach, you shouldn't need a client secret, just the client ID.
I have been trying to get push notifications working using firebase. So far I have got as far as successfully sending an empty message "tickle". The problem is adding the message payload seems to have no affect on what the client receives. That is the service worker just sees it as another empty message.
I started by going through googles guide here - https://developers.google.com/web/ilt/pwa/introduction-to-push-notifications
After going through how to send an empty message it says the message payload must be encrypted and suggests using an existing library to do it. To quote - "As with anything related to encryption, it's usually easier to use an actively maintained library than to write your own code".
I tried to use web-push-php which is one of the libraries recommended by googles guide. After having trouble with that i discovered web-php-push doesn't actually support firebase.
Looking on here i find examples that look really simple and don't event encrypt the message payload. It is simply sent in plain json. Doing this has no affect and the receiving end still thinks it's an empty message. See my code below.
I am at a complete loss with this and i'm confused why googles guide says the message data must be encrypted but there are countless examples on SO where it is just send in plain json text.
This is what i am posting from my server to the end point.
POST https://fcm.googleapis.com/fcm/send Authorization: key=[my server
key] Content-Type: application/json {"priority":10,"to":"[subscriber
id]","notification":{"body":"test body","title":"test title"}}
Here is my event listener in my service-worker.js
self.addEventListener('push', function(e) {
var body;
if (e.data) {
body = e.data.text();
} else {
body = "No message "+JSON.stringify(e);
}
var options = {
body: body
};
e.waitUntil(
self.registration.showNotification('Launtel Residential', options)
);
});
When i run the post request above the push notification occurs and triggers the service worker 'push' event as expected but no message data is present. e.data returns null. The 'e' object always just contains a flag set to true. e.isTrusted==true
I'm having an issue with FCM on flutter. I have implemented messaging from my server so I'm storing my phone token for each user.
The thing is that when a user logs in for the very first time everything works properly, messages are being sent and user gets notified.
If I do not use the app during the weekend, on Monday I try to send a message by doing some actions on my app but messages are not being sent. I can see my token stored properly in my database.
I'm using firebase_messaging 2.1.0 for flutter.
This is how I get my token
_fireBaseMessaging.getToken().then((token){
_myPhoneToken = token;
});
1-I know token may change when:
App deletes Instance ID
App is restored on a new device
User uninstalls/reinstall the app
User clears app data
But none of this happens.
Any advice on how to handle this scenario? thanks in advance.
UPDATE
Provided you have setup the FCM sdk the right way (but you said that it works the fist time you install the app, so I guess so).
Provided that you are sure that the device_token you are using is the one of the device on which you are expecting to receive the notification (check if it's still the same), you should get on this device your notification quite soon if you use "priority" : "high".
{
"to" : "device_token",
"priority" : "high",
"notification" : {
"sound": "default",
"body" : "Test Notification body",
"title": "Test Notification title"
}
}
This method call
_firebaseMessaging.getToken().then((String token)
return always the new token even if it has been updated. So if you print this out on your device and you send a notification on this token without error, there's no reason why you should not get the token if the device has a valid internet connection active.
It's true that the device token can change during time. If you uninstall and reinstall the app, you can see the token will change and if you try to send a notification on the old one, you will get an error.
If instead the token will change during application lifetime, you can be notify on your server side by listening:
_firebaseMessaging.onTokenRefresh.listen((newToken) {
_fcm_token = newToken;
// send the new fcm to your server
});
So first of all I suggest you to be able to send a notification to a device with Postman. Check if the token you are using is still the one on the device. Then you can try to uninstall and reinstall the application and try to use the old token. You will get an error. Then try to send to the new one, and you should get your notification.
Then wait for some days and try again, check if the token has changed or not and if it's not changed you should be able to send the notification without problems with the same token.
Also be aware that data message on Android if the app is terminated are still not supported.
Some networks/router/mobile can cut the connection between firebase library and firebase server due to inactivity (5min without message). This cut may be detected by the library up to 30min (FCM heatbeat interval).
These are some links discussing this issue:
https://github.com/firebase/quickstart-android/issues/307
Android: Delay in Receiving message in FCM(onMessageReceived)
I contacted firebase support but they told that since the issue is caused by external part they cannot fix it (I suggest decreasing heartbeat interval ...)
I fixed it in android using an interval job which apply these instructions:
context.sendBroadcast(new Intent("com.google.android.intent.action.GTALK_HEARTBEAT"));
context.sendBroadcast(new Intent("com.google.android.intent.action.MCS_HEARTBEAT"));
You may write this specific code for Android side and should find something similar for ios side.
I'm using FCM for my push messages. Its great, however I've a client that needs to be able to remove a push message once its sent - (in case of mistakes / typos etc).
I know you can get the message id from when the Topic is queued to send messages, just wondering if there is a way to then use that ID to expire those messages remotely. i.e. to delete the message.
There is currently no way to delete/remove a message from the server side/console. The message_id is just an identifier that the message was sent successfully to the FCM server.
What is usually used for this scenario is the tag parameter (see my answer here) where an existing notification with the same tag gets replaced with the newer one.
There are scenarios where you might want a replacing notification to notify the user rather than silently update. Chat applications are a good example. In this case you should set tag and renotify to true.
write this code on your sw.js
const title = 'Notification 2 of 2';
const options = {
tag: 'renotify',
renotify: true
};
registration.showNotification(title, options);
You can test demo on here by clicking in renotify button
I'm successfully using Bluemix Push to send notifications via the REST interface to an iOS app with a simple string alert message. That works fine.
Now I would like to send a more complex message where alert is a dictionary and has a sibling "category" element per The Remote Notification Payload.
Is this possible with Bluemix Push? Whenever I try to deviate from the basic structure, I get "Bad Request - Invalid JSON".
After much head-scratching, I finally picked up a hint from https://www.ng.bluemix.net/docs/services/mobilepush/t_advanced_notifications.html#t_push_badge_sound_payload and figured out that since the category field is unique to APNS, what I needed to send is
"settings" : {
"apns" : {
"category" : "myCategory"
}
#DSchultz_mo I was having issues to find the documentation but I finally found it, so if you go to https://mobile.ng.bluemix.net/imfpushrestapidocs/#/ you can use swagger to register your device and send notification and the magic button is in model there is more details for sendMessageBody
