I'm trying to sync all calendars in my exchange server with my app, and for that, I am using PHP-EWS: jamesiarmes/php-ews!

After some research, I found 2 options to consider:

  1. Push notifications - I've worked with something similar before, in this case, I should know how it works!

  2. Streaming notifications - I've never worked with this before and I don't understand it, do I need to check from x to x time if there are any notifications for the created channel?

Can you help me choose between the two of them since I don't understand the streaming notification to 100%?

  • There are three kinds of synchronization with EWS. Have a look on [Getting notifications - what are my options?](https://learn.microsoft.com/en-us/exchange/client-developer/exchange-web-services/notification-subscriptions-mailbox-events-and-ews-in-exchange#getting-notifications---what-are-my-options) This should give you an overview on how the different methods work. Maybe then you can choos a method. – LuCio Jul 30 '18 at 14:18
  • @LuCio, I've seen that page before, I mentioned 2 options to consider because I think that the third option "Pull notifications" isn't appropriate for my user case! I need to know if "Streaming notifications" keeps asking what is new to the server! i don't understand that part, thanks for your help. – Christophe Soares Jul 31 '18 at 15:22
  • If your version of Exchange supports it, have you considered using the REST API or Microsoft Graph instead? They have superseded EWS. I think you'll have an easier time with notifications on those. – Richard Fuller Jul 31 '18 at 20:31
  • Yes, i considered the Rest API or Microsoft Graph , but after speaking with someone from Microsoft they say the my case don't support it! Thank you lot again – Christophe Soares Aug 01 '18 at 16:39

With streaming notifications, your client opens a long running HTTP request to the server and the server sends events in the HTTP response over a long period. This can be done without additional software in the client.

With push notifications, you give the server a URL to send notifications to as HTTP requests. This requires that the client have an HTTP server running and an application to process events.

I believe EWS only supports streaming notifications. I'm not sure what that PHP library supports.
