1. Masuk ke https://console.cloud.google.com/
2. Create new project
   
3. Masuk OAuth Consent Screen
   
4. Disini aku pilih eksternal, alasan karena ndak bisa klik internal
   
5. Aku settingannya sebagai berikut
   
   
   Note: disitu ndak bisa diisi localhost atau subdomain, jadi langsung TLD nya, (bukan subdomain). App name diisi dengan id dari project yang dibuat tadi, untuk nyari ID nya, bisa lah dicari. Hehe
6. Aku gak tau, ngaruh atau ndak. Tapi disini aku nambahin emailku
   
7. Kalau udah selesai, sampai summary. Tinggal back to dashboard
8. Masuk ke menu credentials
9. Create credentials, lalu pilih OAuth Client ID
10. Setingannya aku gini, ohh yah untuk redirect. Usahakan sama dengan yang dibuat di OAuth Consent Screen tadi
    
11. Muncul popup kan yah, itu langsung di klik download aja, lalu rename jadi credentials.json
    
12. Buat Projek Baru, isinya file index.php diatas. Lalu tambahkan package google apiclient:
    composer require google/apiclient
13. Pindahkan file credentials.json tadi, satu level dengan file index.php
14. Enable API google drive, disini https://console.cloud.google.com/flows/enableapi?apiid=drive.googleapis.com
15. Jalankan script tadi, dan jeng2. Harusnya berhasil
16. php index.php
17. Kalau error, kabar2
