In modern software development, feature flags are a must-have. They let teams release features gradually, run A/B tests, and control access for different user groups. But there's a common challenge: How do you keep a list of dynamic user segments (like beta testers) always up to date without manually editing the dashboard every time?

To tackle this challenge, I'll show you how to update user segments in ConfigCat dynamically, including examples of setting up and using the ConfigCat's Update Segment API, best practices for managing segment details, and tips for integrating this functionality into your development workflow.

Picture this scenario: you start with a small team building the foundation of your application, gradually adding new features and functionality. As your user base grows, your software should be able to meet the demands of heavier workloads. At this point, the need for scalability arises, driven by the need to keep your application efficient, optimized, and capable. With feature flags, you can manage your user base and scale efficiently.
