How can I fetch transaction updates ?

[arefm]

Hey.

I want to subscribe to my transaction updates. like the total confirmations. I tried to use the txConfirmationSubscribe method which is used by Copay. it returns a success result but I don't know how can I listen to events. I also try the bitcore peer-to-peer message methods and received the inv and address messages. but I didn't receive any tx messages.

would you please help me to understand the tx updates subscription concept and how it works exactly?

Thanks a lot.
