How to invoke REST from JIRA Script Runner Behaviour

Question

Hello

I am following Adaptavist Script Runner documentation to add a behaviour in ServiceDesk (but I guess it would be the same for JIRA core),

and I would like to query a REST endpoint to retreive information to append into custom field description, parameter comes from another form field, reporter in my use case.

I have found no REST endpoint client invocation code snippet except in the specific "select list conversions" example.

What is the best way to invoke a custom REST endpoint to retrieve a single value as a behaviour ?

I expect my behaviour script to call a REST endpoint (whatever it is) and process JSON return... but I have found no example or scriptlet about it - and I am not comfortable with Groovy to guess how to do it.

By the way, I gave up my REST endpoints designed to be registered in "select list conversion" (not available in ServiceDesk yet) and move SQL queries directly into behaviour scripts.

But I am still interested in behaviour script example to invoke REST method and parse JSON anwser.

Do you need help with the REST or the Behaviour?

Behaviour works in service desk portal -https://scriptrunner.adaptavist.com/latest/jira/behaviours-servicedesk.html

You want the customer to enter the rest request and then he will see the result with behaviour ?

Please explain more about the process
