TCGPlayer integration on Magento, singles catalog + market pricing API, how does it work?

TCGPlayer offers two integration surfaces that Magento connects to cleanly:

• Master Card Database API, pulls the full Pokemon / MTG / Yu-Gi-Oh / Lorcana / One Piece master list with TCGPlayer Product IDs, set codes, rarities, foil/non-foil flags. Map each TCGPlayer Product ID to a Magento configurable + simple SKU pair. One-time bulk import for a 50k catalog runs ~2-4 hours.
• Market Pricing API, pulls TCG Low / Mid / Market / Direct Low prices per Product ID per condition (NM / LP / MP / HP / DMG). Magento cron polls every 1-6 hours and triggers price-rule recalculation. Repricing rules I default to: NM = Market price, LP = Market × 0.85, MP = × 0.65, HP = × 0.45, DMG = × 0.25. Customisable per shop margin policy.

Architecture: master catalog lives in Magento (order-of-record) with TCGPlayer Product ID as a custom attribute on each SKU. The pricing engine reads from TCGPlayer Market and writes to Magento price + special_price. Magento becomes the order-of-record; TCGPlayer remains the pricing source of truth. Cuts manual repricing from 3-4 hours per day to a 5-minute admin check. If you sell on TCGPlayer marketplace too, Magento pushes inventory updates back via the same API.
