Kaufland Connector for WooCommerce — offers, prices, stock and Kaufland orders

Kaufland Connector for WooCommerce lists shop products on the Kaufland Global Marketplace through the Seller API: Germany, Austria, Poland, Czechia, Slovakia and the other storefronts open to your account. An offer is created by EAN, and from then on price and stock update themselves. Pro brings Kaufland orders into WooCommerce and sends shipment with tracking, cancellation and the invoice back.

What the buyer sees

A Kaufland buyer finds your product by EAN in the Kaufland catalogue at your shop price, converted to EUR, PLN or CZK with your markup. When a product runs out or you disable it, its quantity on Kaufland becomes 0.

What the admin gets

WooCommerce → Kaufland: keys from the Seller Portal, a connection check that lists the storefronts of the account for you to tick. Then the EUR→CZK and EUR→PLN rates, a percentage and fixed markup, handling time, and the buttons “Send changes”, “Send all”, “Check the catalogue” and “Link existing offers”. The API log keeps no keys and no buyer data.

In Pro, Kaufland orders appear in WooCommerce every 5 minutes, or at once on a push notification. For the first 15 minutes the buyer can still cancel, so the order waits On hold with the stock taken off and moves to Processing once Kaufland gives the address. The order page has a box: mark as sent with carrier and tracking number, cancel, upload a PDF invoice.

How it works, step by step

1. In the Kaufland Seller Portal (Settings → API) you generate the Client Key and Secret Key and paste them into the plugin.
2. “Check connection” reads the storefronts of the account and the shipping groups; you tick the storefronts you need.
3. In products you switch on “Sell on Kaufland” and fill in the EAN; existing offers can be linked with a button.
4. Price and stock changes join a queue; cron sends them every 5 minutes in batches of 150, and the answer is read per offer.
5. In Pro orders come into WooCommerce, and Completed or Cancelled in the shop goes back to Kaufland.

Under the hood

• Every request is signed with HMAC as the Seller API requires; keys are stored encrypted.
• Only changes are sent; batches of 150 offers, and the 207 answer is read offer by offer.
• 5xx and 429 errors are not lost: the product stays in the queue for the next run.
• Push notifications are checked by signature, and the same message is never handled twice.
• WooCommerce e-mails to Kaufland buyers can be switched off.
• HPOS compatible; languages: English, Deutsch, Polski, Čeština.
