Aggregate node
Consolidates multiple items into one array or object — collecting loop results or assembling a batch before storing or reporting.
Aggregate (aggregate) is the collector: after per-item work (usually a Loop), it assembles the results into a single array or object for the next stage.
Configuration
Open the node (double-click) to edit it. Key fields:
- Node ID / Name — the identifier used in variables and the display name on the canvas.
- Aggregation shape — array of items or keyed object.
Inputs & outputs
It receives many items and emits one combined value. Downstream nodes reference its output with {{node_id.field}} — see the variables reference.
