Is it possible get notification on application level on client side in iOS(and Android) whenever some changes happens like new file/folder added or removed on Box.net? Please confirm if SDK supports this behaviour, if not then is there any way to implement this behaviour on client side.
Thanks.
You should be able to get notifications about events happening in a user's account by using the /events endpoint:
http://developers.box.com/docs/#events
Essentially, you'll need to authenticate as the user via OAuth2 and issue an OPTIONS request to the /events endpoint to get a realtime server URL. You should set up a long poller to poll that realtime server, and when it issues a response that notifications are available, issue an authenticated GET request to /events?stream_type=....
Both the iOS SDK and the Java/Android SDKs should support this.

I am implementing Web Push Notification in an application and I have successfully registered the client app with GCM. I have the subscription object that contains the endpoint that looks like this.
"https://android.googleapis.com/gcm/send/dV4lSfI5J6Q:APA91bEU28F9YG5qNr3xSjvYlH2Mh1GPgiqMaRcjandHbpfqnVyAeZxqoE31OXYq4yzW2_vrkn74YHdgsITZP_6SELO8-xHf1hylquJefJdY85-Xx9AWTAPP9H6kfq7CKp23dsoQHbH
I read and found out that we need to use a third party library like web-push to send push using this endpoint to the clients because the payload needs to be encrypted according to spec. My objective is to send notifications to all my users, web + mobile, at once, using Firebase Console's Notification feature.
Is there a way to send push to web clients using Firebase console or to convert the GCM endpoint to an FCM token?
Update: If I try to use Firebase console to send push the token generated above, I get the following error.
As per testing this out, for some reason, registration tokens for Web are not working or allowed in the Firebase Console. Only tokens for Android and iOS do:
The request could still proceed where the console would show that it is sent/complete, but there wouldn't be any messages received.
EDIT: In case it helps others who find this, the fact that Gaia clears cookies after Chrome restart is known behavior. They recommend the use of Chrome login. See more here.
The core question: how do I fetch Google OAuth access tokens in the background from a Chrome extension without using the getAuthToken method in the chrome.identity API? This method forces users to login to Chrome, which isn't ideal for our app. There's also no way I can find to retrieve OpenID Connect ID tokens using the native methods exposed in the identity API.
Currently, I'm fetching tokens using the launchWebAuthFlow method from the chrome.identity API. This method launches an "Identity API Scope Approval UI" window in which the user makes the initial OAuth grant. This window (referred to as "gaia") has its own session / cookie data, separate from a browser session.
After the initial OAuth grant, the extension periodically retrieves access tokens in the background, and subsequently fetches data from Google APIs (e.g. Drive). This works well. When a user quits and re-opens Chrome, however, fetching access tokens fails - gaia loses its session cookies when Chrome restarts, so running the launchWebFlowAuth method doesn't complete because Google can't authenticate the user (unless we prompt the user to login in the Identity API Scope Approval UI again). Others seem to have had the same issue.
Google Sign-In would be ideal, but it doesn't work in Chrome extensions (I'm getting the same "Invalid cookiePolicy" error as the author of that issue).
Any advice on how to best handle this use case would be very much appreciated!
I need advice after looking a lot about receive push/toast notifications regardless of the status of the application (closed or open).
The application communicates with a NodeJS API.
The idea is that a user logs in once to the application and then can receive notifications (depending on his account): i the user restarts his system for example, at startup he receives notifications without having to open the application (like the Mail application for example).
Most tutorials on MSDN use Azure and I don' use this. I would like to know if you have tips or links (tutorials, ...) for doing this in an UWP (or WinRT) application.
Thanks in advance for your help.
Regards
You can send push notifications from your NodeJS api via Windows Notification Service. This service has nothing to do with azure but when using Azure Notifications Hub it will be easier to get it implemented, but again this is not required;
In essence:
- register your app in dev center
- obtain a client id and client secret to use WNS in the dev center
- When your app launch it obtains a push notification channel uri and sends this to your backend. Your backend need to save all the URI's for the different devices
- When you have a notification select the uri's of the devices you want to send the push notification to
- post a xml message (based on what you want to update, tile, toast, badge or raw) to the URI's. To be able to post you need to authenticatie with the client id and client secret

I’m developing chrome push notification for my web site and doing the development in localhost (local machine) environment. Sending push notification is success with specific endpoint which I got when I subscribe the notification first time. I use same endpoint for all push messages.
Here sometime push notification got failed due to endpoint mismatch. When I see in chrome console (debugging mode) there was different endpoint.
Why chrome browser is changing endpoint? In this case how do we handle this scenario and update the new endpoint in the db?
sample endpoint:
https://android.googleapis.com/gcm/send/AWERdvfdfdsfdobRH4zlXGuyeuie3543uTBuP6air5dzZfltNa-FKF6K6S-9P5SdfbCbyvn9RdsfsdvU1XwSBwIrekjdK6_i4Cg-5rZAj8UvL1s-Bbr61yvvt_y2Hg9RdsyV
when i check next time, above endpoint got changed as like below
https://android.googleapis.com/gcm/send/reytryMkQwtY:YTUNMdsjjfhsdf349851VS6McDE7s_GITe_djsgfdkjghcdfdfgdftrkddfdsXiwX1vP_XclmDqrKPOAMJDfsYYXdhMX164694Q&ksdhfksdfhkjfhksdcndsk
Thank you.
The push notification endpoint is dependant on the service-worker. When a service-worker is unregistered and created again, the PushManager.getSubscription() method will indeed return null. You then need to call subscribe() again, which will return a new endpoint.
If you server tries to send a push notification to the first endpoint after the service-worker was unregistered, you will get a NotRegistered (for Chrome) or a Gone (for Firefox) error. So make sure to register the new endpoint as soon as the app loads or the device may become unreachable.
Note that this does not seem to affect service-worker updates.
Either I'm dense, or the docs assume I already know what they're telling me, but I need some clarification on doing authentication for a box.com app. I really don't understand whate's going on. As I read it:
the app running on the user's machine sends a request to Box, including all the little secrets (Which aren't all that secret any more if the user knows how to read the code).
The user is directed to the Box login page, which then sends the user to my server (with no page specified) attaching an authentication code.
The app somehow magically gets that code back from my server and sends a request to Box for the access token.
Box sends the access token to my server?
The app again magically gets the access token from my server and sends its APT requests.
Obviously I got lost somewhere.
And, why do I have to have a server involved in the process? The article on making a JavaScript app refers to a direct request for a token. Is there documentation on that somewhere?
You register your application on Box
After registration you receive clientId and clientSecret once on Box website
You hardcode your credentials somewhere in your application
First time your application needs to access Box API it should redirect user to https://www.box.com/api/oauth2/authorize, specifying your clientId, clientSecret and redirectURI as parameters. About redirectURI see below.
The box.com website opens. User enters his own credentials in the web form on box.com
User allows your application to access his files via API on the box.com website
Box redirects user back to you application using redirectURI specified before. One of the parameters to this request is "code". This is a very short-lived (30 seconds) access code that is only aligable for obtaining real access token.
During next 30 seconds your application should make another call to Box API to next URL: https://www.box.com/api/oauth2/token, specifying the previously obtained code. If everything was correct, your application receives an access_token, a refresh_token and "expires" values.
Now your application can make requests to Box API, specifying access_token every time
access_token expires in number of seconds, specified in "expires" field. It should be about 3600 seconds or 1 hour. Each time your application sees that access_token has expired, it should make another request to Box with the refresh_token and obtain a fresh access_token for another 1 hour.
refresh_token itself expires in 14 days
Note: if you develop a desktop application, then you should open browser for user on the step 4, redirectURI should be something like http://127.0.0.1:8080/Callback and you should run a small webserver just to catch the redirect with the code as in step 7.
Box requires that you specify a redirect_uri in your application's profile, and it must be an HTTPS URL.
As a result, it is not possible to use box with what google's oauth2 documentation calls "Client Side" or "Installed" applications, only "Web Server Applications" are allowed. Web Server applications do not have the secret leaking problem, because only the server knows the secret. You can pass the access token from your server to javascript on the client after
the oauth transaction is complete, if you want the client to make api requests directly.
In your question you are not totally clear in what you are actually trying to produce.
I however suspect that you are trying to write a client application what needs to authenticate to box using the OAUTH2 solution they have delivered in API V2.
If this is for an IPhone for example BOX has a great example of how to handle it.
In a WinForm application you would need to capture the resulting code sent back by box in the browser1.isnavigating event.
Windows console application you register a custom URI registration to collect the code.
Neither of these need to be registered in the API developers Application on box as you would pass the redirect required in the request to box.
If this does not point you in the right direction and your writing a .NET app then post again and I will try to clarify a little more.
Box requires some form user interaction which is short sighted in my opinion but try a web service that simulates a user interaction which then you can save/pass the token to your application to sync up with the Box "Cloud".
