Script Listener is run by REST Endpoint

[Dan27]

Hello,

I would like to run a script listener through REST Endpoint.

I want to put the listener URL in the rest endpoint code here:

document.getElementById("fConvert").action = "/rest/scriptrunner/latest/custom/PublishMail"; 

In this code, the URL reference to another REST Endpoint.

How can I know the URL of the listener ?

Thanks!
