PI Notifications can send messages to a web service (as well as email). It appears only to be able to send to a SOAP web service. We need to send notifications to a Restful web service. How is this possible?
Unfortunately, the Web Service delivery channel does not support REST web services, so a custom delivery channel would need to written.
To add on to Jason's comment, please note that Notifications 2016 R2 (due out very soon!) will not support custom delivery channels just yet.
A small update on this question.
PI Server 2017 supports REST delivery endpoints!
The documentation describes how to do it.
