Can someone tell me on how we can send an email or notification once the push adapter is completed. It's urgent. Is this possible?
There is no OOTB feature like this. ER is welcome.
What you could try to do at the moment is to check job status via web services and then use external tool to send an email.
It looks like https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=wsn should do the magic.
The implementation of workaround isn't officially supported and requires POC...
