Frequently Asked Questions

How often does SyncAuction sync products from Heritage Auctions?
Sync frequency depends on your plan: Starter syncs every 6 hours (4x daily), Professional every 2 hours (12x daily), and Enterprise as frequently as every 15 minutes for near real-time updates. You can also trigger on-demand syncs anytime from the dashboard or via API.
What is the difference between Full Sync and Delta Sync?
Full Sync downloads and processes your entire catalog from Heritage Auctions, ideal for initial setup or catching all changes. Delta Sync only processes products that have changed since the last sync (using checksum comparison), making it faster and more efficient for regular updates.
How are images handled during synchronization?
Images are automatically downloaded from Heritage Auctions with authentication, resized to max 1200x1200, compressed to 60-80% quality for web performance, and hosted on our global CDN (AWS CloudFront). Placeholder images are automatically detected and skipped. We store both obverse and reverse coin images.
What happens if a product sells out on Heritage Auctions?
When a product's quantity reaches zero on Heritage Auctions, SyncAuction automatically unpublishes it from your connected stores during the next sync cycle. If the product becomes available again later, it can be automatically republished based on your settings.
Can I sync to multiple e-commerce stores simultaneously?
Yes! SyncAuction supports syncing to multiple stores (WooCommerce, Shopify, BigCommerce) from a single Heritage Auctions account with shared inventory management. Starter plans include 1 store, Professional includes 3 stores, and Enterprise has unlimited stores.
