API Design First Vs Code First?

Why is API Documentation Important?

Code-First: Faster Development

Pros:

Faster development (Quicker Client Onboarding)

Cons:

Outdated and inaccurate documentation
Wasted time and effort building APIs that don't meet user needs
Difficulty keeping code and documentation in sync

Design-First: Blueprint for Success?

Pros:

Early user feedback and mock server testing

Cons:

Treats design as a one-time phase (design is iterative)
Difficulty in making changes later (immutable services are not always practical)
Risk of creating design-less future versions
