This is the recommended approach for all implementations. Individual Search Engine Endpoints | Engine | Endpoint | When to Use | |--------|----------|-------------| | Central | https://api.indexnow.org/indexnow | Always preferred | | Bing | https://www.bing.com/indexnow | Testing, debugging | | Yandex | https://yandex.com/indexnow | Testing, debugging | | Naver | https://searchadvisor.naver.com/indexnow | Testing, debugging | | Seznam | https://search.seznam.cz/indexnow | Testing, debugging | | Yep | https://yep.com/indexnow | Testing, debugging | **Important:** You never need to submit to multiple endpoints. One submission to any endpoint reaches all engines. --- Request Parameters Deep Dive Required Parameters (POST) | Parameter | Type | Constraints"
