WooCommerce Marketplace Integration: Connect Amazon, eBay, and Galaxus
We connect your WooCommerce store to Amazon, eBay, or Galaxus so products, stock, and orders stay in sync automatically instead of being managed twice.
hechenbros connects your WooCommerce store to Amazon, eBay, or Galaxus so product data, stock, and orders flow automatically instead of being maintained twice by hand. We clarify the right integration method per marketplace, test it with a pilot batch, and only then roll out the full catalog.
What you get
One catalog, multiple channels
Product data is maintained once and passed on automatically to every connected marketplace.
No overselling
Stock is synchronized across channels, including a safety buffer against near-simultaneous sales.
Orders in one place
Marketplace orders flow directly into WooCommerce instead of being handled separately in multiple systems.
Who this is for
Stores ready to sell across multiple channels
Amazon, eBay, or Galaxus should run alongside your existing store.
Stores with complete product data
Barcodes (GTIN/EAN) and category data are ideally already in place.
Stores that want to stop maintaining data twice
Products, prices, and stock should be managed from a single place.
More channels usually means more duplicate work — it doesn't have to
The moment a store starts selling on Amazon, eBay, or Galaxus as well, many businesses end up managing products, stock, and orders by hand across several systems in parallel. That doesn't just cost time — sooner or later it produces errors customers notice directly.
Product data maintained twice
Every change to price, description, or image has to be repeated manually across multiple systems.
Oversold items
When a product sells on two channels at once, actual stock no longer matches what's shown.
Orders split across systems
Marketplace orders land separately from your own store's orders, making warehouse handling harder to oversee.
Unclear approach per marketplace
Amazon, eBay, and Galaxus work differently on a technical level — an approach that works for Amazon doesn't translate directly to Galaxus.
Not every marketplace works the same way
Amazon and eBay can usually be connected directly through a WooCommerce plugin. Galaxus, Switzerland's largest marketplace, additionally requires business approval as a partner and runs on a feed- or middleware-based connection instead.
Amazon
A mature developer API (SP-API) and established WooCommerce plugins, usually ready to connect within days — provided barcodes (GTIN/EAN) exist.
eBay
Its own developer program with a similarly direct path to Amazon, though with category-specific required fields that vary widely.
Galaxus
No direct plugin — connection only follows partner approval, then runs through the partner API or a middleware solution like ChannelEngine.
We check together which marketplace makes sense for your catalog and how realistic the effort per channel actually is.
How it works
Clarify requirements
We clarify whether a seller account already exists, which products should be synced, and whether sync needs to run one-way or in both directions.
Choose the integration method
Amazon and eBay usually use an established WooCommerce plugin; Galaxus or multiple marketplaces at once typically use a feed-based middleware solution.
Map product data
Product data is mapped to each marketplace's required fields, including category, barcode, and marketplace-specific attributes.
Set up a stock buffer
A safety buffer prevents an item from being oversold when it sells on two channels at nearly the same time.
Start with a pilot batch
A small selection of products is synced first and fully tested with a real or realistic test purchase.
Roll out the rest of the catalog
Once the pilot succeeds, the remaining catalog is connected in stages, with error logs checked along the way.
More reach, without more manual effort
A clean marketplace integration opens up additional customers without making product upkeep or order handling any heavier.
Extra reach without duplicate effort
New sales channels open up without product data needing to be maintained more than once.
Fewer errors from manual processes
Stock and orders flow together automatically instead of being reconciled by hand.
Realistic expectations per marketplace
We don't set false expectations — Galaxus's business approval step, in particular, is factored in from the start.
We clarify the right integration method, set up the connection, and test it with a pilot batch before the full catalog goes live.
Frequently asked
Which marketplaces can you connect?
We set up connections to Amazon, eBay, and Galaxus. Amazon and eBay are usually connected directly through a WooCommerce plugin, Galaxus through a partner API or a middleware solution.
Do I already need a seller account?
Yes. Approval as a seller on Amazon or eBay, or as a partner on Galaxus, is a business step that happens before or alongside the technical connection — we can't make you visible on a marketplace you haven't been approved to sell on.
Why is Galaxus more involved than Amazon or eBay?
Galaxus requires partner approval first and has no standalone WooCommerce plugin. The connection then runs through the partner API or a suitable middleware solution.
What happens if a product sells on two channels at once?
We set up a stock safety buffer so an item can't be oversold through near-simultaneous sales across multiple channels.
Do Amazon or eBay orders also show up in WooCommerce?
Yes. New marketplace orders land in WooCommerce automatically, so your team can handle every order from one place.
Does my entire catalog need to be error-free before we start?
No. We start with a small selection of products so any data issues surface early and cheaply, before the full catalog is connected.
What if my products don't have barcodes?
Missing GTIN/EAN codes frequently block approval for individual products on Amazon and Galaxus. We flag this early so it can be resolved before the rollout.
Are marketplace fees reflected in the synced prices?
We work that out with you directly. Marketplace fees can be factored into synced prices, but that doesn't happen automatically without agreeing on it first.
How do I find out if a product gets rejected by a marketplace?
Marketplaces often reject individual listings without an obvious error message, for example due to missing attributes. We actively check the relevant error logs and show you where to see them yourself.
Sell on more channels without more duplicate work
We connect Amazon, eBay, or Galaxus to your WooCommerce store and make sure products, stock, and orders stay in sync automatically.
