Error Handling Patterns in Modern APIs
Inconsistent API errors frustrate integrators and confuse frontend developers. Standardize error shapes across your stack.

Good APIs return errors that clients can act on. Bad APIs return generic 500 responses with no correlation ID.
Use stable error codes
Machine-readable codes like subscription_past_due beat parsing human messages in client logic.
Separate validation from system failures
400-level errors guide user correction. 500-level errors trigger alerts and should never expose internal stack traces publicly.
