1. Change Delta Computation

Rather than re-syncing all 3,000+ products on every poll cycle, the extension computes a change delta — comparing the current WooCommerce API response against the last-known state stored in IndexedDB. Only changed products (price modified, stock changed, title updated) are pushed to marketplaces, keeping API rate usage minimal.

2. Marketplace Field Mapping Engine

Each marketplace has completely different product data schemas. The extension uses a JSON-configurable field mapping layer that translates WooCommerce product attributes to marketplace-specific fields — e.g., WooCommerce regular_price → Amazon fulfillment_availability.quantity + purchasable_offer.price, and Etsy price.amount/divisor. New marketplace adapters can be added via configuration without code changes.

3. Conflict Resolution & Error Recovery

When a marketplace returns an error (invalid category, missing required field, rate limit exceeded), the extension logs the specific error per SKU and schedules a targeted retry. Persistent failures surface in the dashboard with the marketplace's error code and suggested resolution — preventing silent data drift across channels.

4. Cross-Platform Schema Normalization & Error Logging

Data formats vary widely between external platforms. The engine maps diverse schema variations into standardized strongly-typed data contracts, validating field formats before dispatch and streaming diagnostic event logs for rapid issue resolution.
