How to Prevent API Integrations From Leaking Personal Data in Error Messages

Validation and exception messages can include submitted values that are then copied to logs or returned to clients.

Checks to make

Review error responses and logs with synthetic data, return stable non-sensitive error codes, and redact personal fields before recording context. Restrict diagnostics access and define retention for support traces.

When to get help

API engineering can improve error handling and sensitive data redaction. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
