Summary
- Supports two execution modes: "Run Once for All Items" (recommended for 95% of use cases) and "Run Once for Each Item" for specialized per-item logic
- Access data via $input.all(), $input.first(), or $input.item; always return array format [{json: {...}}]
- Built-in helpers include $helpers.httpRequest() for HTTP calls, DateTime (Luxon) for date operations, and $jmespath() for JSON querying
- Critical gotcha: webhook data is nested under .body property, not at root level; common mistakes include missing return statements, incorrect return format, and expression syntax confusion
