id

The id() function returns the current row’s page ID, or the page ID of a specified page. This page ID is a unique string.

The page ID can also be found at the end of a Notion page’s URL (before any query strings starting with ?).

id() outputs a string that is guaranteed to be unique for each page in a database. It is possible for all other properties – including Name – to contain the same value in multiple rows.
