Wat is de Custom Platform + Allegro integratie?

Koongo connects your Custom Platform to Allegro via API, syncing product listings, inventory, pricing, and orders to one of the leading marketplaces in Central and Eastern Europe. Whether your store runs on a proprietary system, a headless setup, or a specialized platform, Koongo connects your product data to Allegro's 22+ million buyers. The Allegro Integration Wizard handles setup step by step - no custom development required. Product configuration, order synchronization, and listing submission are covered through the wizard, with the built-in health report flagging issues before they affect your account. Allegro orders are imported back into your order management system once live. Koongo also offers predefined templates that simplify setup for custom environments. The Category Mapping tool retrieves Allegro's per-category required attributes, and the Rules Editor maps your store data to them. Koongo also maps Polish content from your existing store fields into Allegro's structure, since English listings won't reach Polish buyers.

Key Benefits:

What it takes to sell on Allegro - and what trips merchants up

Poland's dominant marketplace Allegro is Poland's leading online marketplace, with roughly 22 million active buyers against a population of about 38 million. Its catalog spans electronics, home goods, fashion, automotive, and groceries, and it's also growing in the Czech Republic and Slovakia.

Polish-language listings reach buyers Allegro accepts English listings, but Polish shoppers won't find or trust them - listing in English is the most common reason non-Polish merchants fail on Allegro. Koongo maps Polish content from your existing store fields, such as metafields or translation-app output, into Allegro's required structure, though it doesn't translate the text itself.

Per-category attribute parameters Allegro uses a structured, per-category attribute taxonomy similar to eBay's item specifics. Required fields vary heavily by category - electronics, fashion, and automotive each have their own mandatory parameters. Koongo's Category Mapping tool retrieves Allegro's required attributes per category, and the Rules Editor maps your store data to them.

Mapping and order sync, handled Attribute mapping flows through Koongo's Rules Editor, alongside Allegro Category Mapping, configured once and applied automatically on every sync. Order sync back to your store runs via the standard per-channel sync mechanism, so Allegro orders and inventory stay aligned with your store.
