n8n Node Configuration Each n8n node has its own parameter shape, often with conditional fields (parameter X only matters when parameter Y has value Z). Shapes evolve between versions. Guessing produces cryptic validation errors. Don't guess, use the get_node_types tool. Non-negotiable Call get_node_types with discriminators (resource, operation, mode) before configuring a node. Without discriminators you get the generic shape, missing operation-specific parameters and required fields. Build against the exact shape. Don't guess from memory. The live get_node_types output is the canonical parameter shape. The references in this skill cover patterns, gotchas, security rules, and decision-making (when to use which operation, why credentials over text fields, engine retry caps, etc.) not parameter names or field structures. If a reference example conflicts with what get_node_types returns, trust the tool. Markdown drifts; the type def is generated from the live source. Never guess resource-locator or load-options values. When get_node_types shows a param with @searchListMethod or @loadOptionsMethod (Slack channels, Sheets tabs/docs, DB tables/columns, model lists, labels), resolve the real value with explore_node_resources (pass a credentialId from list_credentials ) and use a returned value . If you already know the exact ID, use it; if several match and intent is ambiguous, ask the user. An invented ID validates but points at nothing. Exception: toolWorkflow.workflowId has no search method, resolve it via search_workflows and use mode: 'id' . Strong defaults Configure operation-first. Set resource and operation first, and conditional parameters become visible. Most "field doesn't exist" errors are really "you haven't set the parent operation yet." Don't carry parameters across operations. When changing operation , re-derive from the new shape. Stale parameters from the previous operation trip validation.
