味道

Visit the Notion webapp and use your browser developer tools to see the network requests being made when you type in anything to the quick find search bar.

Here you'll see a request called search, check the request headers to copy the cookie value and check the request payload to copy your notionSpaceId.

Known issue: Some users have experienced issues with copying these values directly from developer tools, but have seen success by copying and pasting the values into TextEdit or a different text editor first, this probably "strips out" or removes any problematic formatting.
