Do I need security testing for public APIs?

Yes — if your API is public, you should absolutely do security testing.
Public APIs are exposed to external users, third-party apps, bots, and attackers, so they need testing for things like:
- Authentication and authorization flaws
- Broken object-level access control
- Injection attacks
- Rate limiting and abuse protection
- Data exposure / excessive data leakage
- Misconfigured CORS and headers
- Input validation issues
- Token/session security
- Logging and error handling leaks
A good baseline is to test against:
- OWASP API Security Top 10
- Your auth flows and access controls
- Common abuse cases like scraping, brute force, and enumeration
If the API handles sensitive data, money movement, account actions, or customer records, security testing becomes even more important and should be done before release and regularly after changes.
If you want, I can give you:
- a lightweight API security testing checklist, or
- a full test plan mapped to OWASP API Top 10.
