I'm leading the development of a new internal REST API that will serve as the backbone for several future customer-facing applications, and I'm trying to establish design standards that will ensure consistency, scalability, and ease of use for other development teams. I'm grappling with several fundamental decisions, such as the best approach to versioning endpoints, designing meaningful and predictable resource hierarchies, and implementing comprehensive error handling that goes beyond basic HTTP status codes. For architects and senior developers, what are the most impactful REST API design principles you've adopted that improved long-term maintainability? How do you balance pragmatic simplicity with the need for future extensibility, and are there specific tools or frameworks for API documentation and contract testing that have proven essential for enforcing these standards across a growing organization?
