REST API: best practices and mistakes to avoid
A well-designed API simplifies integration, reduces client-side bugs and makes changes easier. An improvised API quickly becomes technical debt that is hard to fix.
Summary
1. Consistency matters more than trends
A good REST API remains predictable: clearly named resources, consistent HTTP methods, explicit filters and stable response formats.
2. Security and validation
Every endpoint must check permissions, filter exposed data and reject invalid input. Security must not be added only at the end.
A robust API is a trusted interface between your data, tools and users.
