Can you call a rest endpoint from a custom listener?

Question

I have a fragment(button) that calls a rest endpoint, this works great and is pretty simple. The Rest Endpoint queries data and returns the result which updates the issue. This works great, for certain conditions we want to setup a listener to automatically initiate the logic defined in the rest endpoint, struggling with how to reference this.

Within a listener is it possible to call an already defined rest endpoint script instead of re-doing it? What format is it expecting to pass a string parameter such as an issue key?

This seems like it should be an easy reference I'm missing, perhaps it's not possible to reference the endpoints from the listeners?   Thanks

@BaseScript CustomEndpointDelegate delegate

doSomething(issue.key)

The above will error and adding {} after it will create a child reference within the existing script and also update the permission of the endpoint to anonymous.

this doesn't solve the problem calling a restricted Scriptrunner REST Endpoint from a workflow event while it is an anonymous user...

So the first step is to access your script editor

http://192.168.0.17:8080/plugins/servlet/scriptrunner/admin/scriptEditor

Then you can create a folder to organize your code, in my example I created a helper folder.

Then you can add here the code that does all the heavy work and you would like to share it with your Listener and Rest endpoint, in my case my code will return all components from a project key, and it can filter by what the user is typing ( I had this from a previous question),

Here you can find my code:

Then you can use this code importing your new class in your Rest endpoint , workflow condition/validator/post-function or Listener, simple example here how to import and run in Console:

And you can then reuse in your Listener in the same way, below is how I did in my example:

Notice that I've used a singleton pattern so all usage will use the same object, but feels free to test and do as you need. This way to can leave the REST endpoint for the integration you are looking for and if you need to access the shared code you can import and do it through JAVA API instead of calling a rest function.

Let me know if you have any question on that and if that helps you
