n8n-node-configuration

Start with get_node using standard detail to see required fields for your chosen resource and operation, configure the minimal set, then run validate_node and iterate on errors. Most configurations succeed within two to three validation cycles.

Fields are hidden by displayOptions rules until their dependency conditions are met, such as body appearing only when sendBody is true and method is POST. Use get_node with search_properties mode to find what controls a field's visibility.

Use standard detail first since it covers about 95 percent of configuration needs with a small response. Escalate to search_properties mode for specific fields, and reserve full detail for cases where the complete schema with displayOptions is genuinely needed.

Different operations require different fields: posting a message needs channel and text, while updating needs messageId and text. Always re-check requirements with get_node after switching resource or operation values.

Auto-sanitization fixes operator structure issues like adding singleValue for unary operators such as isEmpty in IF and Switch nodes. It does not add missing required fields like channel, which you must configure yourself.
