Is it possible to write REST API plugin for cloud?

[Rich Scire]

We have a REST plugin for Jira Server and I need to migrate that to the cloud. Is it possible to write a plugin that creates a new REST endpoint?

Sort of.

Cloud apps do not plug directly into the Jira Cloud "server", they either live alongside it, or they are external to it.  Whichever way you do it though, their only access to Cloud is via Cloud's REST API.

So, the short answer is a technical "no" - you can't write apps that provide REST endpoints directly in Cloud.  But you can write apps that provide their own REST endpoints and talk to Cloud about what arrives on those.
