Third Party Services

Google (Google OAuth + Google Drive API)

What it is used for:

• Connecting your WordPress site to Google (OAuth)
• Listing/searching files and folders from Google Drive
• Opening/downloading files via Google-hosted URLs

When data is sent:

• When an administrator clicks Connect Google and completes authorization
• When anyone views a page that contains the [sg_doc_library] shortcode (your WordPress site fetches file/folder metadata from Google to render the library)
• When a visitor uses Search / Open / Download inside the library
• When the plugin refreshes an expired access token (if you have connected with offline access)

What data is sent:

• During OAuth authorization (admin action): client ID, redirect URI, state, requested scope, and an authorization code
• During API calls to Google Drive: an OAuth access token (in an Authorization header), Google Drive file/folder IDs, and search terms entered by the user (if search is used)
• During Open/Download (visitor action): your WordPress site returns a redirect URL and the visitor’s browser is sent to a Google-hosted URL containing the file ID (for example docs.google.com export links or drive.google.com download links)

Data flow / conditions:

• Google Drive API requests are made server-to-server (from your WordPress site to Google) using the OAuth token stored in your WordPress database.
• The visitor’s browser is only sent directly to Google when the visitor clicks Open or Download.

Endpoints contacted:

• https://accounts.google.com/o/oauth2/v2/auth
• https://oauth2.googleapis.com/token
• https://www.googleapis.com/drive/v3

Visitor browser destinations (when using Open/Download):

• https://docs.google.com/
• https://drive.google.com/

OAuth scope:

• https://www.googleapis.com/auth/drive.readonly

Stripe (Donate link)

What it is used for:

• Optional donations via a Stripe-hosted checkout page

When data is sent:

• Only when an administrator clicks the Donate button in the plugin admin page

What data is sent:

• The plugin itself does not send payment details. Clicking Donate opens a Stripe-hosted page in your browser. Stripe then receives the data needed to load and process the checkout (such as your IP address, browser/user agent, and any information you enter on the checkout page).

Plugin settings

Google OAuth

Client ID
The OAuth 2.0 Client ID from your Google Cloud project. Find it under APIs & Services > Credentials > OAuth 2.0 Client IDs in the Google Cloud Console.

Client Secret
The OAuth 2.0 Client Secret from your Google Cloud project. It is stored encrypted (AES-256-CBC) in the WordPress database. Leave the field blank to keep the existing stored secret when re-saving settings.

Redirect URI
A read-only field showing the URI you must register as an Authorized Redirect URI in your Google Cloud Console OAuth client. Copy it with the Copy button and paste it into Google Cloud Console before clicking Connect Google.

Connect Google / Disconnect
After saving your Client ID and Client Secret, click Connect Google to start the OAuth authorization flow. Once the authorization is complete, the status shows Connected. Click Disconnect at any time to remove the stored OAuth token.

Libraries

Name
A label for your own reference to identify this library in the admin. It is not visible to visitors on the frontend.

Public Folder Share URL
The sharing URL of a Google Drive folder. The folder must be shared with “Anyone with the link can view” in Google Drive before it will work with this plugin.

Access
Controls who can browse this library:

• Public: Anyone, including non-logged-in visitors.
• Logged-in users: Only authenticated WordPress users.
• Specific roles: Only users with the selected WordPress roles.

Allowed roles
Only shown when Access is set to Specific roles. Check all WordPress user roles that should be allowed to view the library. Visitors not matching a selected role will see an access denied message.

Hide Open button
When enabled, the Open button is hidden in the file list. Visitors cannot open files in a new browser tab directly from the library.

Hide Download button
When enabled, the Download button is hidden in the file list. Visitors cannot download files directly from the library.

Remove header from frontend
When enabled, the breadcrumb navigation and the search bar at the top of the library are removed from the frontend display. Useful when you want a minimal, non-navigable file list.

Icon is preview of file content
When enabled, Google Drive preview thumbnails are loaded as file icons instead of generic file-type icons. This provides a visual preview of each file’s contents, but may slightly increase page load time for large folders.

Frontend language
Sets the display language for this library’s UI elements (buttons, status messages, labels). Defaults to the WordPress site language if left on Default. Change this per library if you need a different language than the site default.

Root folder label
Custom text displayed as the label for the top-level breadcrumb in the file explorer. Leave empty to use the plugin’s built-in default root label (typically “Root” or its translation).

Allowed file extensions
A comma-separated list of file extensions to show in the library, e.g. pdf,docx,xlsx. Leave empty to display all file types from the Google Drive folder. Extensions are matched case-insensitively.
