Our app is supposed to track the statistics of the user’s account (after his approval) for demonstrating it to our app’s user. To provide that, we need to get real-time notifications when:
- somebody unfollows our user;
- our user follows another user;
- another user follows our user;
- our user unfollows somebody.
Our app will be located on 2-3 servers and would be able to maintain several thousands of our users. That means that we can’t use User Stream API and also it’s unavailable to make the request for Site Stream API for now.
We’re interested in Account Activity API service, but we noticed the limit of 50 subscribers for a single app. We’re planning to have much more subscribers after the app launch.
So, we’re curious if it is possible to implement the recieving of the notifications listed above from the big amount of users using several servers?
Also, is it possible to refresh our database real-time to show our users following/unfollowing statuses using Account Activity API?
Finally, is it correct that we can’t obtain the information about unfollowers via User Stream API or with another method?
Thank you in advance,
