Knowledge Base & Operational DocumentationHow to Protect an API Integration From Sending Sensitive Data in Error Logs
Debug logging can capture authorization headers, personal records, payment details, or full request bodies. Logs may be accessible to more people and retained longer than the application database.
What to check
Review logging levels, exception handlers, request tracing, third-party observability tools, and retention settings. Use synthetic test data to identify what is recorded and who can access it.
Recommended next step
Redact secrets and minimize sensitive fields before logging, restrict log access, and rotate credentials if they were exposed. Preserve useful request IDs and error context without storing unnecessary payloads.
