Receive notification when user cancels MS Store subscription? - windows

I'm currently research if there any way to get notify our server when subscription status had change (expired or cancelled manually). I had read two related articles:
https://learn.microsoft.com/en-us/windows/uwp/monetize/change-the-billing-state-of-a-subscription-for-a-user
https://learn.microsoft.com/en-us/windows/uwp/monetize/enable-subscription-add-ons-for-your-app
For now the only way I see, is to check status on purchase validation via Azure, which happens on login in my case (which is not notification obviously), disadvantages of this approach that there would be a ton of notification from each user who logon, even if there no any changes in subscription.
Another possible options (I guess) is to send notification using WNS or Azure, according to articles:
https://learn.microsoft.com/en-us/windows/uwp/design/shell/tiles-and-notifications/windows-push-notification-services--wns--overview
https://learn.microsoft.com/en-us/azure/notification-hubs/notification-hubs-windows-store-dotnet-get-started-wns-push-notification
I see it's possible to send direct notifications to cloud service, but I can't find any information on how to subscribe to user subscription changes, is it even possible?

How to get message events published on a Web API endpoint and feed it to bot framework v4 (C#, .Net Core Bot)?

I am using a third party API to provide Agent Handover (human chat) capabilities to my v4 based bot. The API requires a call back hook/ endpoint where it can send the messages/events back from the agent, and I have to get messages from it and display to users. When ever a new chat session is established a new session id is generated. And thus Session Id is passed back in all messages and events. Essentially they are sending events as Fire&Forget with a retry on failure.
For now I had implemented an eventstore (in Cosmos dB) to store events/messages and then poll Cosmos periodically display message back to user and mark them processed.
Is there any way to make it more real time or pub-sub kind of analogy?
I would like to know if some one have already implemented scenario like this. What should be the way to respond the incoming messages from agent to bot user.
Please suggest.
I would recommend creating a client using the Direct Line API to handle routing messages between the third party agent handover and the bot. Then in the bot you can pair the third party Direct Line conversation references with the user's conversation reference to forward the messages accordingly with proactive messages. For more details take a look at this Stack Overflow question.
Hope this helps!

Slack App API - Can I subscribe to and monitor all #username mentions for the current user?

When someone mentions a specific username by their handle in Slack, the user typically gets notified about that mention by Slack. I would like to make a Slack app that subscribes to those notifications for the current user. Any time a user gets notified that they were directly mentioned, I'd like to be informed of that in my app, along with the contents of that message.
I've looked through the API docs for quite a while and I can't seem to find support for this functionality. Am I missing something? Can this be done?
There is no event in the Slack Event API that handles mentions of users (although if you create a slack bot you can handle mentions of the slack bot's user with the app_mention event).
You can still listen for the message event and manually look through the text for any #UserMentions and handle them there. Note that this will only work for channels that the Slackbot has been granted access to.

Design Slackbot service to send automated messages

It is my very first time to write a slack bot and i am wondering how to design it.
The bot supposed to be available and respond to end-users' messages immediately.
The thing is that I need that the bot will also send schedules messages to registered users with automation results.
Use case example:
A user sends a message to the bot and registered to a service that
will check for changes in X. On a specific interval, my backend will
call an automation that checks for those changes and will send a
message to the user with the results.
What will be the best practice for this scenario?
Here is a basic outline.
1. Basic setup
Slack app with bot user
Database
Scheduler (e.g. local CRON service, or web-cron like cron-job.org)
2. Registration
Use Events API to listen to messages from users send via mention (app_mention) or direct message (message.im)
You app needs to store the received "registration" from each user in a database
Respond to user request directly if needed with chat.postMessage
3. Scheduled response
Scheduler calls your app
Your app check if responses are due with a database query
If yes: App sends responses to users via chat.postMessage (but not more than one message per sec due to rate limiting)

How do I receive only the messages that are direct messages to my bot user?

I have successfully setup my slack bot app, have enabled events etc. I want to receive any direct messages that the members of my slack team send to my bot. For this, I have only enabled Bot Events and No Team Events like below
However, I do not get any event on my webhook on this setting.
If I enable message.im event under Team Events, then I start getting events. But then, I get every message that the user (who has installed the app) sends to any other user in the team.
How do I get only the messages that are sent to my bot user?
Update 1
Based on this SO question I created a private channel with the bot user. Even then, the messages in the private channel do not arrive in my webhook with the above event subscriptions.
Update 2
After reinstalling the app, it seems to be working fine. I have only used it for few minutes after the reinstall so far. I will keep posting here how it goes. It would still be interesting to know what went wrong where.
It is normal behavior that your script receives all messages (for every channel your bot is a member of), not only the messages sent directly to your bot. At this time you can not filter further in the event configuration. So you need to filter out any unwanted message in your script handling the event.

Regarding uable to trigger Paypal REST API webhook events from developer sandbox

What is wrong with my Paypal sandbox account process
to receive webhook notifications? We are unable to receive webhook event on
my URL.
URL working with "Webhooks simulator". Please let me know what
should I do for receive webhook event on above URL.
Webhooks simulator sends sample payloads for the events you configured. It does not send a notification on triggering of an actual event.
If you are getting notification via Webhooks Simulator, it means the URL configured by you is able to intercept POST requests.
Now for the "Paypal sandbox account unable to process to receive Webhook notifications" part, please check if the transaction is actually created at https://developer.paypal.com/developer/dashboard/sandbox/ . If the transaction you are looking for is not present there, there won't be any notification generated. In case transaction is present there and still you are not getting any notifications, please share debug id.
Here is a silly thing that I overlooked in the documentation and only found out after contacting support.
After you've followed the approval url and gave your approval, dit you execute the payment with the REST API?
https://developer.paypal.com/docs/api/payments/#payment_execute
Webhooks are only called after you've executed the payment.
The confusing part is; there is no webhook being called, when a user approves or cancels a payment. There is only a redirect back to a return url or cancel url. So you either need to monitor the redirect back to your site and trigger the execute call then, or find another way (like polling the payment) to see the status change before calling the execute call.
