There are a couple of Notion hacks that I can think of off the top of my head that require a Notion Token v2. The first, is required in order to create a Notion-based website and the other to use Chilipepper , a form embed for Notion. Here is how to find your v2 token.
Use Google Chrome, and sign into your Notion workspace.
Right click anywhere inside the page and select "Inspect."
Locate "Application" and select "Cookies." Here you should be able to find "token_v2." Copy the property next to it called "Value."
