How to add to my url formula button that changes a checkbox to ""true"

you are not in the right place,

You need to go to the Application home page
Settings (gear)
App Properties
Require Application Tokens (normally checked) (what does this mean?)
     Go to the Manage Application Token page to assign a token to this application (only required for API calls).
