id

Learn how to use the id function in Notion formulas.

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.

id()
id(page)

page.id()
Code language: JavaScript (javascript)

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.

/* Page URL: <https://www.notion.so/thomasfrank/id-c5d67d15854744869cc4a062fb7b1377> */
id() /* Output: c5d67d15854744869cc4a062fb7b1377 */

prop("Related Pages").first().id() 
/* Output: c5d67d15854744869cc4a062fb7b1377 */
Code language: JavaScript (javascript)

This example database uses the id() function and string concatenation to return the URL of each page within the database.
