Every feature and capability Topsort offers is accessible through our comprehensive API suite, giving you maximum flexibility to build exactly what you need.

Perfect for companies with in-house development teams who want to deeply integrate advertising into their platform's unique architecture and workflows. ## Who Is This For? Ad Server is ideal for: * **Enterprises** with in-house engineering teams and custom requirements * **Technical teams** needing full control over ad logic and ranking algorithms * **Businesses** requiring deep integration with proprietary systems * **Platforms** with unique auction mechanics or custom workflows **Want a faster setup?** If you need quick deployment without extensive API integration, explore [Ad Platform](/en/ad-platform) instead. ## Key Benefits Full control over every aspect Build your own ranking algorithms Integrate with proprietary systems Access to all API capabilities ## Core APIs Build your advertising platform using three foundational APIs: ### Catalog API Keep your products, categories, and vendors synchronized with Topsort.
