Documentation & Support

External Services

Mercantor connects to Google services that you explicitly authorize in order to publish and monitor your Merchant Center listings.

Google Merchant Center API

Endpoint: https://merchantapi.googleapis.com
Purpose: Creates, updates, and inspects Google Merchant Center product listings on your behalf.
Data sent: Product identifiers, titles, descriptions, image URLs, pricing, availability, shipping settings, and other product attributes required by Google. Customer or order information is never transmitted.
When data is sent: During the guided connection flow and whenever automated or manual sync jobs run.
Authentication: OAuth 2.0 using the https://www.googleapis.com/auth/content scope. Access and refresh tokens are stored securely in your WordPress database and can be revoked from the Mercantor settings page.
Terms of Service: https://policies.google.com/terms
Privacy Policy: https://policies.google.com/privacy

Privacy Policy

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 Settings Disconnect Google.
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.

Roadmap / Upcoming

Stricter Content Security Policy (CSP) rollout for the admin app
Opt-in telemetry with diagnostics export bundle (logs, payload samples, system info)
Scheduled health checks and automated diagnostics refresh
In-product fix recipes and support macros for top Merchant Center errors
