API review

Spring Boot API review for contracts, errors, security, logs and maintainability.

A focused review for REST APIs that need more predictable contracts, clearer errors, better observability and safer evolution.

When this route is useful.

A frontend, mobile app or partner integration depends on an API with unclear behavior.
Errors are hard to interpret and support cannot explain failures quickly.
The API evolved without clear DTOs, validation, documentation or logging rules.

Scope

Evaluate endpoints, methods, response formats, status codes, DTOs and versioning expectations.

Review validation, exception handling, error messages, sensitive data and support signals.

Check logs, documentation, monitoring signals and deployment validation for API flows.

Yes. API review is stronger when it considers app authentication, offline behavior and error display.
