# Zalando > Zalando is Europe's leading online platform for fashion and lifestyle. Its zDirect Platform (Merchant/Partner Platform) exposes OAuth2-protected REST APIs for the full article lifecycle: products, attributes, prices, stock, offer availability, orders, sales channels, logistic centers, and Zalando Fulfillment Solutions (ZFS) stock movements and cross-border reporting. APIs follow the Zalando RESTful API Guidelines and use JSON:API and problem+json media types. ## Developer - [Developer Portal](https://developers.merchants.zalando.com/): zDirect Platform developer home - [Documentation](https://developers.merchants.zalando.com/docs/index.html): getting started and guides - [Quick Start Guide](https://developers.merchants.zalando.com/docs/quick-start-guide.html) - [Authentication](https://developers.merchants.zalando.com/docs/auth.html): OAuth2 client credentials - [Rate Limiting](https://developers.merchants.zalando.com/docs/rate-limiting.html): 429 + Retry-After / X-Rate-Limit - [Release Notes](https://developers.merchants.zalando.com/docs/release-notes.html): dated changelog - [RESTful API Guidelines](https://opensource.zalando.com/restful-api-guidelines/): Zalando's public API design standard - [GitHub](https://github.com/zalando) - [Engineering Blog](https://engineering.zalando.com/) ## APIs (OpenAPI) - [Orders API](openapi/zalando-orders-openapi.yml): retrieve merchant orders, items, lines - [Products API](openapi/zalando-products-openapi.yml): create/update catalog products - [Product Attributes API](openapi/zalando-product-attributes-openapi.yml): enumerate valid attributes - [Article Requirements API](openapi/zalando-article-requirements-openapi.yml): UAF requirement outlines - [Merchant Price Service API](openapi/zalando-prices-openapi.yml): set article prices by country - [Price Reporting API](openapi/zalando-price-reporting-openapi.yml): price status + history - [Merchant Stock Service API](openapi/zalando-stocks-openapi.yml): manage article stock - [Offer Blocking API](openapi/zalando-offer-blocking-openapi.yml): block/unblock article availability - [Sales Channels API](openapi/zalando-sales-channels-openapi.yml): merchant sales channels - [Logistic Centers API](openapi/zalando-logistic-centers-openapi.yml): merchant logistic centers - [ZFS Stock Movements API](openapi/zalando-zfs-stock-movements-openapi.yml): fulfillment stock movements - [ZFS Cross-Border Movements API](openapi/zalando-zfs-cross-border-movements-openapi.yml): inter-warehouse transfers ## Artifacts - [Authentication](authentication/zalando-authentication.yml) - [OAuth Scopes](scopes/zalando-scopes.yml) - [Conventions](conventions/zalando-conventions.yml) - [Error Catalog](errors/zalando-problem-types.yml) - [Lifecycle](lifecycle/zalando-lifecycle.yml) - [Changelog](changelog/zalando-changelog.yml) - [Sandbox](sandbox/zalando-sandbox.yml) - [Data Model](data-model/zalando-data-model.yml) - [Conformance](conformance/zalando-conformance.yml) - [Agent Skills](skills/_index.yml)
