Shopify

The most complete integration: bidirectional sync plus webhook-driven price and stock, with the events MarketplaceHub subscribes to.

Shopify is the most complete integration: source, publishing target, and a price and stock source of truth that pushes rather than being polled.

Importing from Shopify

Products are read straight from the store — no export step. They arrive with the collection they belong to.

Publishing to Shopify

Content and price/stock are separate submissions, so stock can move without republishing.

Shopify as your master store

This is what makes Shopify different. Shopify supports webhooks, so MarketplaceHub registers for the events it needs and changes arrive as they happen rather than on a schedule:

• Product created or updated — the product is upserted into your catalog.
• Product deleted — the product is delisted from your other channels and removed.
• Stock changed — matched by SKU, dirty-checked, and propagated to your other channels.
• App uninstalled — the connection is marked dead and you are notified, so a disconnected store fails loudly rather than going quiet.

Propagation excludes Shopify itself, so a stock change in your store updates Amazon and eBay without writing back to the store it came from.

Latency

Webhook-driven, so effectively immediate — the delay is the time to write to the other channels, not a polling interval. This is the main practical difference from Etsy, which has no webhooks at all.
