The Set node (also called "Edit Fields") adds, modifies, or removes fields on items. Use it to reshape data as it flows through your workflow.

Modes

Manual Mapping -- Define fields one by one using the UI. Pick a field name, type, and value (static or expression).
JSON Output -- Define the entire output as a JSON object. Useful for building complex nested structures.

Parameter	Description
Fields to Set	Define field name, type (String, Number, Boolean, Array, Object, Date), and value
Include Other Input Fields	When enabled, passes through all input fields alongside the ones you set
Duplicate Field Resolution	When including other fields, choose whether set values override or are ignored

Option	Description
Ignore Type Conversion Errors	Continues execution when a value cannot be converted to the specified type
Support Dot Notation	Allows `user.name` to create nested objects like `{user: {name: value}}`
Include Binary Data	Preserves binary file data through the transformation

Rename fields: Set a new field with the old field's value via expression, then exclude the old field
Strip to essentials: Enable "Keep Only Set" to output only the fields you define
Build nested JSON: Use dot notation or JSON mode for complex API payloads
