For now creating new googledrive api + verify them so hard,
you need to input video how api's works, plus give full source code to the google team and last, you should input all required and optional form on console.
If one or more form is empty you likely get rejected
here the example of verified screenshoot
if you not get this screenshoot. you will not able to login (ummm you still can login through but you will have "app not verified" page before you login)
(screenshoot for api using on sharer.nesia.my.id) - ordinary googledrive sharer script after yuudrive lol
so for now (2021) i will strongly suggest to you to make your own direct download from googledrive that doesn't require user to login, so you didn't need to go into verify process that take a lot time, and ended rejected.
if you ask how to verify googledrive api through google console, then you will difficult to follow any tutorial regarding that, because for now, the detail and requirements added more and more, so yeah... i will strongly suggest to make your own googledrive downloader that download from serverside proxy or more like
rifky.nesia.workers.dev or
sharer.my.id (my project)
booth two of them didn't require any action or login from users
users can only click download button on the website
going through safelink (if you have) or can directly go to download page
worker or
sharer
so that's all my suggest to you, i hope you understand my point,
The era is change, your download link should be change also, rather than using old script, you must search the new ones on this babiato, if the alternative didn't found, you can search on github, there's a lot of it....
my sharer.my.id also appear after i search a lot of script on github and i have idea to create my own sharer without user's action such as login
and if you run a webdownload like... film, music, or software...
i strongly suggest you to have multiple download link,
minimum 4
and i suggest for you to have 2 or 3 of that 4 link is hosted by you,
on my case i have
sharer (normal sharer), Sharer without login, direct download googledrive worker, and multiup mirror
so if some of the link broke, i can change it to new ones without limiting the download to the user,
when i change the link, they can still download from other link
that's all... thanks
