> I have a common piece of JS code that needs to be called from a number of rules, that I have tested and working in the OH3 UI Scripts interface. I just can’t work out how to actually call the script from a rule.

A library or a Script (as shown in the Script page in MainUI). If the latter, you can’t find the ID because it’s not a Rule so it doesn’t have an ID. If the latter, why not the former? See [OH 3 Examples: Writing and using JavaScript Libraries in MainUI created Rules](https://community.openhab.org/t/oh-3-examples-writing-and-using-javascript-libraries-in-mainui-created-rules/108526).

If you have a Script (i.e. it’s defined through the UI and appears in the list on the Script page, I don’t know how much I can help without more information.

I’ve circled the UID of the Create Rule Example in the screen shot above. That’s the ID you need to use.
