Major upgrades to API keys in 2025 will enhance user and organizational capabilities by allowing the generation of API keys for various applications, such as creating a public-facing API, non-web app authentication, and internal machine requests. These improvements provide deeper insights into API key usage through detailed usage charts, allowing breakdowns per user, organization, or individual key. Users can now enforce custom rate limits to prevent abuse and manage enthusiastic customers, while proactive notifications will alert customers about impending API key expirations, ensuring continuous service without interruptions.
