OLX Poland

About OLX Poland

OLX Poland provides a Partner API for integrating with the OLX classifieds marketplace, covering posting and managing adverts and communicating with OLX users through an internal messaging system. The same API documentation applies across OLX sites in Europe. It also exposes endpoints for OLX Delivery (Przesyłki OLX), a shipping feature available in Poland that lets sellers offer shipping options on ads and buyers pay online and track deliveries; related endpoints cover delivery settings, category-level delivery methods, and delivery method fields on adverts. Delivery is limited to specific categories and subject to maximum item price and size limits.

Authentication uses OAuth 2.0, requiring a client_id and client_secret obtained from OLX, with access tokens (bearer) and refresh tokens (valid for one month). Supported grant types are authorization_code (for user actions like adverts and messages), client_credentials (for fetching config data such as categories and cities), and refresh_token. Requests must include a Version header, and multilingual sites support an Accept-Language header for switching languages. The API is intended for partners integrating advert posting, management, and messaging functionality into their own applications.
