One way to find a record ID, outside of an API response, is to grab it from your Builder. You can do so by navigating over to your records in the Builder.
Although this is easiest done with Chrome, similar steps can be taken from most browsers. From the object, make sure you’re looking at your records and then right click near the checkbox on the record's row you're working with, then click on Inspect Element.
You’ll see a console window open up. From that window, find the table row element for that specific record and notice the ID is a long string of characters. This is the unique record ID that can then be used in your custom code.
