A well‑designed API layer is the backbone of any SaaS platform. It defines how internal modules communicate, how external integrations work, and how reliably the system behaves under load. Poor API design leads to inconsistent data, hard‑to‑debug issues, and slow development.

A maintainable API follows several important rules:

Consistent naming
