Refund Imports — Valid Row Export

Use this endpoint when you have a CSV of refund records and need to isolate only the valid rows before importing them into a downstream system. It is ideal for lightweight, self-contained validation without external enrichment, supports quoted cells, and enforces category allowlists and numeric range constraints in a single call. Prefer it over generic CSV validators when you need refund-domain-aware presets and a clean valid-row export rather than just an error report.

• CSV exceeds 100,000 character limit — request rejected
• CSV contains more than 1000 rows — rows beyond limit may be truncated or rejected
• Delimiter mismatch causes parsing errors — all rows may appear invalid
• Cell exceeds max_cell_length threshold — affected rows marked invalid
• Numeric values outside the min/max bounds — those rows excluded from valid export
• Malformed CSV structure (unclosed quotes, wrong column count) — parsing failure or row-level errors
• Payment not processed — endpoint returns 402 before any validation occurs
