I'd like to monitor a users gmail account for new messages and take an appropriate action. Is there a way to fetch the history events for just new messages but NOT for things like starring an email or changing its labels, etc.?
So I ended up using messages.list and storing the timestamp of the most recent message. Then on subsequent calls to messages.list I'd supply a query of "after:theMostRecentTimestampIKnowOf" to find new messages since the last time we synced.
Another route I've seen done, is if you have the ability to add a filter (e.g. user's can do that, or use the Google Admin SDK for Google Apps users, or do it through HTML/DOM hacking) then you can simply setup a filter to apply a label to all new messages. Then just messages.list(labelId=THAT_LABEL) when you do your polling (and remove it after you process them).
There is not any ability now to filter history based on change type, though it's something that would be nice to provide at some point.

I'm designing a custom team tab using React that calls third party API, I need after executing the API successfully, user gets notified . What is the best way to achieve this? I used Bot in my project, but not sure how can I call it from my custom tab class. I'm aware of the existence of proactive messaging, is it the only way to do it? If it is, a pointer on how to implement it to a custom tab would be appreciated.
If you're wanting to message the user 1-1 (like in the personal app), then proactive messaging is definitely what you need (inside a Team, there are other options), and considering you have the bot already in place that's perfect. The only thing you might be missing are the details required to send the actual proactive message (the best time to get them is when the bot is first installed by the user). In particular, you need ConversationId and ServiceUrl.
With regards the concept of Proactive Messaging, basically once the bot is installed, and you have the required values, you can -send- the message from any backend code at all. That can include, for example, custom tab's backend api. You need to identify the user, which you can do using the Teams Context (it's not the safest way but it's the easiest), and then look up the values in your own backend store (e.g. database or whatever) to get the ConversationId and ServiceUrl, then just message the user in your backend.
I am creating an AdminUI for my users where I set all the permission. As part of the requirements, every time that a user logins on my IdentityServer I need to set some default permissions, but those are handle on my Admin application. Which is the best way to raise an event to let that application that a user was created on the IdentityServer?
The simplest is i think to create a simple WebApi in IdentityServer that returns the latest users and then let the other application poll this API every X seconds. In that way the system is cleanly decoupled. Perhaps expose the data as a a RSS XML document or a JSON list of items.
There is a built in eventing model in IdentityServer that you could use and push notifications to the Admin application. But push is a bit more complicated to get right, especially how to deal with all the failre/error cases.
I's suggest to add a custom event sink to process UserLoginSuccessEvent or any other event you need, here is list of all builtin events. Find their code here.
In the custom sink as suggested in the other answer you can call an API on admin app to inform it about changes.
Here is a sample for custom sink.
I think to keep two applications decoupled you better to setup a service-bus for simple implementation a sub/pub mechanism. when any user complete registration(or any other actions),then as mentioned in another answer handle the events and add message. admin UI should subscribed before to receive these messages with some information to create a user related data.
I'm building an app using MEAN Stack (something like Facebook). So a user can login to my app using different browsers and I want for example, if there user will add a new message to the MongoDB, I want to update his messages in the other sessions. The same of he will remove a massage. At the same time, there maybe logged in different users from different browsers and I want to notify the user with his update in the other sessions.
Does Socket.io supports such an option? And what is the best way to do it?
Thanks.
Yes socket.io do support that. Here is an example made by socket.io themselves: https://github.com/socketio/socket.io/tree/master/examples/chat
You should be looking for socket.on() which are the listeners for an event on the server side and look into socket.emit() which are the senders of the events. the .emit()could be added into an function which are triggered on a button click for example.
Depending on you needs, if you're going to send the message to every user using your app then you could use this above code. But if you only wants to send to a specific list of persons you should look into something called Rooms (http://socket.io/docs/rooms-and-namespaces/#rooms).
This does exactly what it sounds like, it emits the messages to the specific room where users have been added to when they connect to your application.
What is Synchronizing client with gmail ? Can anybody give a detailed explanation, because i want to have a better understanding over this concept.
For example, if your client keeps any local cache of the Gmail mailbox data like the Message.Id and labels, or headers, or the entire email. Then in order to update your client you're synchronizing it with Gmail--pulling new updates down to your client. In cases of clients designed for offline use, then synchronizing may also mean pushing local updates back up to the server (e.g. label updates made by client while "offline" that get applied at some later point). That's the general definition of synchronizing.
For the Gmail API specific case, Gmail has a backend mailbox-wide history Id. Any change that affects that account in any way gets a history identifier and most (but not all) history changes affect the state of email messages. Like adding a new message, changing the labels on a message, or deleting a message. Clients of the Gmail API can poll the history Id and find out what's changed since the last time they synchronized and pull down updates to maintain their sync.
I want to be notified of changes to users or groups in sling's userManager as they happen. For example, when a new group is created, I need to create a new node with the same name under /content. When a new user is created, I want to give them write-permissions for /content/foo. And similar tearDown steps when objects are deleted.
I tried registering a EventHandler (org.osgi.service.event.EventHandler), with event.topics set to "*" (all topics), but this captured only resource changes and not userManager changes because users and groups are synthetic resources (I think)
I tried using a org.apache.sling.api.request.SlingRequestListener, but the SlingRequestEvent did not come with any info that would help me distinguish the request (or I didn't know how). Also, I am not sure if this is can even be used for callbacks that need to be called AFTER the request is processed.
I have used Filters for a different issue and I tried applying them for this purpose too. But they have their limitations - My filter is called BEFORE the request, so it's not possible to know if the request will result in SUCCESS before deciding to take action.
Any suggestions on how to listen and respond to changes in sling's user and group models?
In https://issues.apache.org/jira/browse/SLING-977 Ian Boston suggests using a SlingPostProcessor service to be informed of calls to the user management's POST servlets.
I haven't tried it myself, and if you do it you might anyway miss changes that are done via Sling's user management APIs - but that might be good enough depending on your use case.
Apart from that I don't think there's currently a surefire way of being notified of such changes. To implement that in Sling we'd need to wrap the org.apache.jackrabbit.api.security.user.* objects (Group, User, UserManager) to send events when they're changed. Certainly doable but would require changes to that Sling bundle.
