ShipWave Channels

ShipWave Channels overview

Sell on Amazon, eBay, Etsy, Walmart, and TikTok Shop from one dashboard, with or without a connected storefront.

What is ShipWave Channels?

ShipWave Channels is a multi-channel marketplace connector that lets you list your products on multiple sales channels from a single dashboard. Manage your catalog and inventory directly in ShipWave, or connect Shopify, BigCommerce, or WooCommerce if you already sell there. No storefront or marketplace connection is required to get started; connect individual marketplaces when you are ready to list and synchronize inventory. ShipWave pushes listings to each marketplace, keeps inventory in sync, imports orders, and syncs tracking numbers—all automatically. Instead of logging into five different seller portals, manage everything from one place.

Supported marketplaces

Amazon – Seller Central integration via SP-API. Supports Amazon US, Canada, Mexico, and Brazil. Works with both FBA (Fulfillment by Amazon) and FBM (Fulfilled by Merchant) listings.
eBay – Full listing and order management via the Trading API and Inventory API. Global marketplace support.
Walmart Marketplace – List on Walmart's third-party marketplace. Authorized from the Walmart App Store with OAuth 2.0; there are no API credentials to enter.
Etsy – Product sync with Etsy-specific attributes like materials, tags, and shipping profiles. Uses OAuth with PKCE for secure authorization.
TikTok Shop – Sell directly through TikTok's in-app shopping features. Multi-shop support via shop cipher.
European marketplaces – Allegro, Bol.com, Cdiscount, Otto, Kaufland, and Mirakl-powered storefronts each have their own connection guide in this help center.

Three ways to run your catalog

ShipWave keeps one product and inventory record for everything you sell. You choose where that record comes from:

Standalone in ShipWave – Create products under Admin → Products → New product with titles, images, variants, SKUs, prices, and quantity on hand. ShipWave holds the inventory count; no store connection is needed.
A connected storefront (optional) – Connect Shopify, BigCommerce, or WooCommerce under Admin → Stores. The store supplies the catalog and inventory, ShipWave mirrors it, and changes flow to every marketplace channel. Shopify changes arrive by webhook and marketplace orders are written back to Shopify automatically; for BigCommerce and WooCommerce, order mirrors, stock updates, and tracking are enabled from the store page after the first catalog sync and store verification.
Marketplaces connected individually – Each marketplace is authorized on its own and uses your ShipWave catalog or connected store as its product source. eBay and Etsy can also be connected as their own source with no other store. Walmart currently requires a connected Shopify, BigCommerce, or WooCommerce store as its product source.

You can override any product field per channel, so the same catalog can read differently on each marketplace.

How it works

Add your products – Create them in ShipWave, or connect your Shopify, BigCommerce, or WooCommerce store to import products, variants, and inventory levels.
Create a channel – Go to Admin → Marketplace → Channels, click Connect Channel, pick the marketplace, and choose the product source (your connected store or your ShipWave catalog; eBay and Etsy can be their own source). Authorize your seller account with OAuth. Walmart connections start from Walmart Seller Center's App Store.
Configure settings – Set up pricing rules (markups, rounding), inventory buffers, category mappings, and listing templates.
Create listings – Select products to list on each channel. Apply per-listing customizations if needed.
Push to marketplace – Products sync from your catalog to the marketplace with your customizations applied.
Manage from one place – Orders auto-import, inventory stays in sync across all channels, and tracking numbers push back to each marketplace when you ship.

FAQs

Do I need a Shopify store to use ShipWave Channels?

No. You can manage your catalog and inventory directly in ShipWave, or connect Shopify, BigCommerce, or WooCommerce if you already sell there. A store connection is only needed to exchange products, inventory, and orders with that platform.

How often does inventory sync?

Marketplace orders trigger immediate cross-channel inventory updates. If you connect Shopify, inventory changes arrive by webhook within seconds; BigCommerce and WooCommerce stock changes arrive through their store sync. Quantities you edit directly in ShipWave go out on the next reconciliation or when you click Sync Now on the channel. A safety-net reconciliation runs twice an hour (at :21 and :51) for every channel.

Can I use different prices on different marketplaces?

Yes. Each channel has its own pricing rules. You can set percentage markups, fixed dollar markups, rounding rules (to .99, .95, or .00), minimum/maximum prices, and custom formulas. Rules can be conditioned on product type, vendor, tags, SKU, or price range.

Is there a limit to how many products I can sync?

No. ShipWave Channels can handle catalogs with thousands of products. Bulk operations and background processing ensure large catalogs sync efficiently.

Can ShipWave publish to a marketplace I have not connected?

No. Each marketplace must be connected and authorized (through OAuth, or through Walmart's App Store) before ShipWave can create listings, sync inventory, or import orders there.

What happens if a marketplace is down during sync?

ShipWave logs the error and retries automatically. The sync log shows exactly what failed and why. You can also trigger a manual re-sync once the marketplace is back online.
