<h3>External Services</h3>
<p>Mercantor connects to Google services that you explicitly authorize in order to publish and monitor your Merchant Center listings.</p>
<h4>Google Merchant Center API</h4>
<ul>
<li><strong>Endpoint</strong>: https://merchantapi.googleapis.com</li>
<li><strong>Purpose</strong>: Creates, updates, and inspects Google Merchant Center product listings on your behalf.</li>
<li><strong>Data sent</strong>: Product identifiers, titles, descriptions, image URLs, pricing, availability, shipping settings, and other product attributes required by Google. Customer or order information is never transmitted.</li>
<li><strong>When data is sent</strong>: During the guided connection flow and whenever automated or manual sync jobs run.</li>
<li><strong>Authentication</strong>: OAuth 2.0 using the <code>https://www.googleapis.com/auth/content</code> scope. Access and refresh tokens are stored securely in your WordPress database and can be revoked from the Mercantor settings page.</li>
<li><strong>Terms of Service</strong>: https://policies.google.com/terms</li>
<li><strong>Privacy Policy</strong>: https://policies.google.com/privacy</li>
</ul>
<h3>Privacy Policy</h3>
<p>Mercantor connects to the Google Merchant Center API only after you complete the OAuth consent flow inside the plugin. We transmit product catalog data (titles, descriptions, pricing, availability, images, and required attributes) so your listings stay in sync with Google. Customer, order, and analytics data are never sent. OAuth credentials are stored in the WordPress options table using secure WordPress APIs and can be revoked at any time through Mercantor <span aria-hidden="true" class="wp-exclude-emoji">→</span> Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Disconnect Google.<br />
On uninstall, Mercantor drops its custom database tables and deletes its options (including OAuth tokens, feed tokens, and setup data) so no plugin data is retained.</p>
<h3>Roadmap / Upcoming</h3>
<ul>
<li>Stricter Content Security Policy (CSP) rollout for the admin app</li>
<li>Opt-in telemetry with diagnostics export bundle (logs, payload samples, system info)</li>
<li>Scheduled health checks and automated diagnostics refresh</li>
<li>In-product fix recipes and support macros for top Merchant Center errors</li>
<li>Optional GA4 tracking toggle with consent-mode compatibility</li>
</ul>

<p><strong>Merchant Center Reviews for WooCommerce</strong> connects WooCommerce with Google Customer Reviews / Google Merchant Center review features.</p>
<p>The plugin adds the Google Customer Reviews opt-in prompt to the WooCommerce order confirmation page, helping eligible stores request post-purchase feedback from customers. It also lets you choose a clear review-display mode: Google’s current floating <strong>store widget</strong> for bottom-left or bottom-right placement, or the <strong>legacy Google Customer Reviews badge</strong> for inline shortcode placement or old floating badge behavior.</p>
<p>The checkout opt-in data is only output on a valid WooCommerce order-received URL after the order key has been checked. The optional Google Tag Manager/dataLayer event is privacy-minimized and excludes direct customer contact and address fields.</p>
<h4>Key features</h4>
<ul>
<li><strong>WooCommerce checkout opt-in</strong> – automatically displays the Google Customer Reviews opt-in prompt on the order confirmation page.</li>
<li><strong>Google Merchant Center ID setting</strong> – enter your numeric Merchant Center ID in a dedicated WooCommerce admin page.</li>
<li><strong>Opt-in placement controls</strong> – choose supported Google opt-in styles such as center dialog, bottom tray, bottom-left, bottom-right, top-left, or top-right dialog.</li>
<li><strong>Estimated delivery date</strong> – set the number of delivery days used for Google’s review invitation timing.</li>
<li><strong>Product GTIN support</strong> – sends valid GTIN values when available using WooCommerce’s global unique ID field and common GTIN/EAN/UPC metadata fallbacks.</li>
<li><strong>Clear display mode selector</strong> – choose New Google store widget, Legacy Google Customer Reviews badge, or no display.</li>
<li><strong>New store widget controls</strong> – choose bottom-right or bottom-left placement and optional desktop/mobile margins using Google’s current <code>merchantwidget.js</code> integration.</li>
<li><strong>Legacy badge controls</strong> – keep the old Google Customer Reviews badge for <code>[gmc_review_badge]</code> inline placement or old bottom-left/bottom-right floating placement.</li>
<li><strong>Optional GTM/dataLayer event</strong> – pushes a privacy-minimized event to an existing dataLayer or gtag setup when enabled.</li>
<li><strong>WooCommerce and HPOS-friendly</strong> – reads order data through WooCommerce CRUD methods and declares custom order table compatibility.</li>
<li><strong>Defensive loading</strong> – checks WooCommerce availability, validates settings, and avoids exposing order data when the order key is invalid.</li>
</ul>
<h4>Where to configure it</h4>
<p>After activation, go to <strong>WooCommerce -> Google Merchant Center Reviews</strong> to enter your Merchant Center ID and configure checkout opt-in, review display mode, new store widget settings, legacy badge settings, script placement, debug mode, and optional GTM tracking settings.</p>
<h3>External Services</h3>
<p>This plugin connects to Google services to facilitate Google Customer Reviews / Merchant Center review features. It loads Google’s store widget script from <code>https://www.gstatic.com/shopping/merchant/merchantwidget.js</code> when New Google store widget mode is enabled. It loads Google’s platform script from <code>https://apis.google.com/js/platform.js</code> on the WooCommerce Thank You page to allow customers to opt in for review requests, and when Legacy Google Customer Reviews badge mode is enabled.</p>
<ul>
<li><strong>Service Used</strong>: Google Merchant Center Reviews / Google Customer Reviews</li>
<li><strong>Data Sent for Review Opt-In</strong>: Merchant Center ID, order ID, customer email, delivery country, estimated delivery date, and product GTIN data when available. The plugin validates the WooCommerce order key before outputting this data on the Thank You page.</li>
<li><strong>Purpose</strong>: Enables Google to send review invitations after a completed order and displays Google’s current store widget or the legacy Google Customer Reviews badge when enabled.</li>
<li><strong>Terms of Service</strong>: <a href="https://policies.google.com/terms" rel="nofollow ugc">Google Terms</a></li>
<li><strong>Privacy Policy</strong>: <a href="https://policies.google.com/privacy" rel="nofollow ugc">Google Privacy</a></li>
</ul>
<p>Google may collect aggregated engagement data for the store widget. The current store widget mode passes widget placement and margin settings to Google; it does not pass customer order data. If the optional GTM/dataLayer event is enabled, the plugin sends a local browser event to the site’s existing analytics/tagging setup. The plugin does not load Google Tag Manager itself. The event payload is limited to event name, order total, currency, order number, item count, shipping country, and product ID/SKU/quantity/line total data; it does not include customer name, email, phone number, street address, postcode, city, or customer ID.</p>
