GDrive requires several steps to configure.

You will start at the API credentials manager:\\
[https://console.developers.google.com/projectselector/apis/credentials]\\
\\
You first need to make a project.  My example calls this CrushFTP-Test.\\

\\
Next select create credentials, and choose the Web Application type.\\

\\
It will warn you if you don't have an "OAuth Consent" screen configured, so go there and configure that screen too.\\

\\
When configuring the credential, you have to tell Google the domain you will be originating from when creating the auth token, so this is the URL you use for server administration.  Just the protocol://dns_or_ip:port   Don't have a trailing slash or it will complain.\\
You also need to put in the redirect URL of where google is going to send you back to after approval.  This needs to follow the syntax in the example.  Specifically your domain needs to end with:\\
{{{
?command=register_gdrive_api
}}}

\\
And one last important step, you need to enable the GoogleDrive API for your account fi its not already.\\
[https://console.developers.google.com/apis/library/drive.googleapis.com/]\\
[attachments|enable_api.png]\\
\\
Now that the API is enabled, and your credentials are setup, and your redirect domains are configured, you can use the credentials in CrushFTP to get your google auth token and get access.\\
In the User Manager, add a new remote VFS item type and set the protocol to be "GDrive".\\
Take your google client_id and secret and combine them together with a ~ as separator:\\
{{{
client_id: 725111111110-7kaimtXXXXXXXXXXXXXXXXXXXXX64m4k.apps.googleusercontent.com
secret: fEsXXXXXXXXXXXXXXXXPggg7
}}}
results in:
{{{
725111111110-7kaimtXXXXXXXXXXXXXXXXXXXXX64m4k.apps.googleusercontent.com~fEsXXXXXXXXXXXXXXXXPggg7
}}}
That whole long garbage string becomes your "username" to GDrive://.\\
Copy and paste it into the user field.  Then click "Get Refresh Token" to finish the config.\\
