How to Troubleshoot an API Integration That Rejects Valid File Names

An integration may reject file names containing spaces, Unicode, punctuation, or long extensions because of inconsistent encoding, validation rules, or path handling. Users may rename files to work around the issue and lose traceability.

What to check

Record a sanitized failing filename and compare encoded request, validation response, path normalization, storage limits, and operating system behavior. Test safe examples that vary one character class at a time.

Recommended next step

Define supported filename rules and normalize safely without discarding meaningful characters. Keep the original name as metadata when storage paths require a transformed value.
