## Description

MPSIndex helps service businesses and B2B companies turn structured customer and
partner feedback into visible business proof.

This plugin is a lightweight connector for the MPSIndex hosted service. It provides
real WordPress functionality without copying the MPSIndex application into WordPress:

 * Explicitly connect one WordPress site to an MPSIndex account.
 * View a simple list of MPSIndexes owned by the connected account.
 * Copy a shortcode for a completed, displayable MPSIndex.
 * Render the MPSIndex as a responsive, server-rendered card on a post or page.
 * Open MPSIndex to manage the account or invite customers.
 * Disconnect and revoke the site’s connector credential.

Use a shortcode copied from **MPSIndex > My MPSIndexes**:

    ```
    [mpsindex id="your-index-id"]
    ```

The default card size is medium. Optional responsive sizes are available without
a design builder:

 * `[mpsindex id="your-index-id" size="small"]`
 * `[mpsindex id="your-index-id" size="large"]`

An MPSIndex account is required. The external service offers a Basic account and
paid plans. The Basic account can use the default single-card display when the connected
account and MPSIndex are eligible. Plan rules, limits, billing, invitations, and
index management remain in the MPSIndex service; this plugin does not lock or unlock
PHP features.

The plugin has no hidden tracking, advertising, automatic backlinks, remote executable
code, or admin nags. It does not contact MPSIndex merely because it was installed
or activated.

#### External service

This plugin connects to `https://app.mpsindex.com` to authorize the WordPress site
and retrieve MPSIndexes owned by the connected account. The connection is necessary
for the plugin’s account list and shortcode display features.

No external request is made on installation or activation. A site administrator 
must select **Connect MPSIndex**, then explicitly approve the exact site on MPSIndex.

During connection, the plugin sends:

 * The WordPress site URL and callback URL.
 * A random state value and PKCE code challenge used to protect the connection.
 * A short-lived authorization code and PKCE verifier during the server-to-server
   exchange.

After connection, the plugin sends a site-bound, revocable connector token in server-
to-server requests. It retrieves limited account metadata (display name, plan, and
status) plus display data for the account’s own MPSIndexes, such as an opaque index
ID, provider name, score, date, company name, logo URL, website URL, evaluated areas,
and footer text. Invited customer email addresses and the MPSIndex account login
token are not sent to this WordPress plugin.

Responses are cached locally for up to five minutes. The connector token is stored
as a non-autoloaded WordPress option and is not placed in a page’s HTML. If an account-
provided logo URL is displayed, a visitor’s browser requests that image from its
stated URL.

### Privacy

The plugin suggests service-specific wording in **Settings > Privacy** so site administrators
can include it in their privacy policy. See the **External service** section for
the exact data flow and links.

The plugin itself adds no analytics or tracking and does not create an automatic
public backlink.

## Installation

 1. Upload the plugin folder to `/wp-content/plugins/` or install it through the WordPress
    Plugins screen.
 2. Activate **MPSIndex – Customer Feedback & Business Proof**.
 3. Open **MPSIndex** in the WordPress admin menu.
 4. Select **Connect MPSIndex** and approve this site on MPSIndex.
 5. Copy a shortcode from **My MPSIndexes** into a post or page.

## FAQ

### Do I need an MPSIndex account?

Yes. If you do not have one, the plugin provides a link to create an account on 
the MPSIndex service.

### Does the plugin collect reviews inside WordPress?

No. Customer invitations, structured feedback, account management, and billing stay
in the MPSIndex service. The plugin connects, lists the account’s own MPSIndexes,
and displays eligible completed indexes.

### Can a Basic account display an MPSIndex?

Yes, when the connected account is active and the completed MPSIndex is eligible
for the service’s default basic display. The service remains the source of truth
for current plan limits and capabilities.

### Does the plugin send data before I connect?

No. Installation and activation do not contact MPSIndex. External communication 
begins only after an administrator explicitly starts the connection.

### What happens when I disconnect?

The plugin asks MPSIndex to revoke the site credential, then removes the local credential
and cache state. It does not delete or alter the MPSIndex account or its indexes.

### What happens when I uninstall?

The plugin removes its local options and cached data. Uninstall does not make an
external request, so use **Disconnect** first if you also want the remote credential
revoked.
