I'm trying to create a google apps script project where is required to access by anyone (people with google account) and executed by the same user (user accessing the web app). I've published the app as "web app" and it work with the given url.
Since i need to this web app as a web service using ajax, the browser console return an error of unauthorised access (No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'x' is therefore not allowed access.) this doesn't happen if the web app is published as "Executed by my" and "access by anyone, even anonymous"
anyway, i'm following the instructions in Google Sign-In for Websites and it said i need to access in google developer console to get credential for the project but my google apps script are not displayed in the project list.
