During January 2026, this developer enhanced the segmentio/action-destinations repository by implementing EU data residency support for the Heap Cloud destination. Leveraging Node.js and TypeScript, they introduced a region enum and a user interface dropdown to enable dynamic selection between US and EU endpoints, ensuring GDPR and data residency compliance for European customers. Their work included updating routing logic and creating a getHeapBaseUrl helper to support scalable multi-region configurations. Comprehensive unit tests were added to validate endpoint routing and resilience to region changes. The feature improved data routing accuracy and laid the groundwork for future multi-region support within the platform.
