Then you can create Google Drive folders and upload files in it!

2. How it works? What can I do with GG Drive?

How does it work?

WP File download will generate a root folder on your Google Drive with the site name.

All the folders and sub-folders added in WP File Download will be synchronized under this folder (WP File Download - {sitename}). And vice versa, all your files and categories from that root folder on Google Drive will be synchronized to your WP File Download dashboard on Wordpress.

What are the sync directions?

It works in both directions! You can add a file from Google Drive and see it in WP File Download or add a file in WP File Download and see it in Google Drive. It also means you can manage WordPress files from your desktop using Google Drive sync software. That’s crazy! Yes we know ☺

Also if you erase a file from Google Drive you have to empty trash to erase it from Google Drive.

Get rid of the error: error: "invalid_scope when connecting WP File Download with Google Drive"

Google has recently introduced a new security layer that forces apps to be verified. If you've created the app with your Google account and then you log in from WordPress with the very same account you won't see this error.
This error will only appear if you've created an App with a Google account and trying to connect to Google from WordPress with another account.

In this case, you need your app to get approved by Google following this process: https://support.google.com/code/contact/oauth_app_verification

3. Create a Google Drive App

The Google Drive integration is distributed as a separate Add-on. You need to install this add-on (plugin) additionally to WP File Download. The addon includes integration for Google Team, Dropbox, OneDrive, Amazon S3 and Nextcloud too.

First, you need a Google dev App to connect your website to Google Drive. Go to https://console.cloud.google.com/ and navigate to the top-left, click Burger Menu > IAM & Admin > Create a Project.

Then set up a project name (no accent)

Then wait a few seconds for the project creation…

If it's the first time you're using the Google Drive API, you should go to Navigation menu > APIs and Services > Library to activate it.

From the left menu, click on “Navigation menu > APIs & Services”

Then on the left menu “Credentials”, on the main panel click “ + Create Credentials” >> OAuth client ID.

If it's the first time you use this, a warning appears: "To create an OAuth client ID, you must first configure your consent screen" you should click on "Configure consent screen" button or go to APIs & Services >> OAuth consent screen. Then following the Project configuration.

1. App Information: App name, User support email

2. Audience: Internal is often for accounts in an organization or team and External is for personal accounts.

Internal: your app is limited to Google Workspace (known as G Suite) users within your organization. You will not need to submit your app for verification.
External: your app will available to any user with a Google account but your app should be public and verified.

3. Contact Information: fill your email address

4. Finish: Agree with Google API Services

Finally, click the "Create" button. After processing, you will be redirected to the OAuth Overview page. Then, click on "Create OAuth client" button.

Now, the most important step.

Select “Web application” and add a name of your choice.
Authorized JavaScript origin: https://your-domain.com (replace by your domain name, no slash, no www.)
Authorized redirect URIs: https://your-domain.com/wp-admin/admin.php?page=wpfdAddon-cloud&task=googledrive.authenticate
(replace it with your domain name, or you can copy it directly from the plugin settings for accuracy)

Then… voilà! You have your ID and Secret to add to the WP File Download configuration.

And, navigate to Audience tab, if it's currently Testing, you should click on "Publish app" button to change the status. The publishing status should be Production.
