Infrastructure, not a marketplace

An infrastructure layer, not a marketplace.

clasify is not another marketplace and does not compete with your platform. We are the tooling layer in front of it: sellers create their articles once, centrally, with AI support for title, description, category and price. They then publish their listings on the platforms where they want to sell.

The transaction, the communication and the relationship with the buyer stay entirely on your platform. clasify makes sure that more listings, and better maintained ones, arrive there.

Benefits

What an integration does for your platform.

01

More supply

clasify lowers the biggest hurdle in listing: the effort. A photo becomes a complete ad in seconds, so items go online that would never have been listed without clasify. On top of that, multi-platform publishing brings listings from professional dealers to marketplaces those dealers have not served so far. For your platform, both mean more supply with no acquisition effort of your own.

02

Better data quality

Every listing created through clasify has a meaningful title, a complete description, the right category and a market-based price. Structured product data improves search, filtering and recommendations on your platform and cuts down on back-and-forth between buyers and sellers. Fewer “See photos, message me with questions” ads, more listings that buyers can really find and understand.

03

More active sellers

Sellers who manage their listings centrally work measurably more reliably: they respond faster to enquiries, keep their ads current, reliably remove sold items and publish more regularly. The very metrics that show the health of a marketplace improve when sellers work with professional tools.

04

New seller groups

Through clasify's shop connections, you reach dealers who have so far sold only in their own online shop. Shopify dealers can bring their product range to marketplaces with no extra work. For shop systems, the same applies in reverse: your dealers gain additional sales channels without leaving your system. That strengthens their loyalty to your platform.

05

A clean, controllable integration

clasify is an identifiable partner with a clearly defined interface. Instead of uncoordinated individual tools and scraping solutions, you get one point of contact, transparent access and the option of defining rules and limits together. An official integration creates control where uncontrolled sprawl would otherwise grow.

Two ways to work together.

Marketplaces

An inflow of supply and quality

For classifieds and trading platforms, clasify is an inflow of supply and ad quality. The integration ideally runs through an official API with OAuth, so sellers connect their accounts securely and clasify can create and manage listings on their behalf. We agree on scope, permissions and limits together.

Shop systems

A bridge to marketplace selling

For shop systems, clasify is the bridge to second-hand and marketplace selling. Dealers bring their products over from the shop and publish them on connected marketplaces, including automatic sync of stock and product data. The Shopify integration is live, and other systems such as WooCommerce and Shopware are planned.

Technology

Structured data, defined processes.

At the core of clasify is a unified product data model that describes articles across platforms and, on publishing, translates them into the format of the target platform. Categories, attributes and shipping options are mapped cleanly rather than freely interpreted.

For the integration itself, we follow your technical and content requirements. Whether REST API, OAuth flows, sandbox environments or review processes: we have built integrations with several platforms and with Shopify, and we know what it takes in terms of stability, rate limits and data protection. clasify is developed and operated by Clasify GmbH in Germany, GDPR-compliant and with infrastructure in the EU.

Rooted in the German classifieds market.

clasify is not starting from scratch. For years, the team behind clasify has been building tools for the German classifieds market, and it runs Kleinanzeigen-Enhanced, a browser extension for Kleinanzeigen.de, Germany's largest classifieds marketplace, actively used every week by more than 16,000 sellers. That experience flows directly into the clasify ecosystem of app, business platform and integrations.
