Pass data between steps

Use variables to pass a trigger's data or an earlier step's result into another step.

Insert a value

1. Open the step and select a field.
2. Choose Insert variable, type {{ for suggestions, or drag a field from the input panel.
3. Choose the source field. Use Edit variable syntax when you need to inspect its path.

Variables appear as chips. Unavailable fields show an error and Needs attention on the node.

A single variable in a numeric, JSON, or condition field keeps its original type. Text fields and variables mixed with text convert values to text.

Inspect and transform data

The step inspector shows input, configuration, and output. Choose structure, table, or JSON view; table view shows collections as rows. Phones use tabs for these panels.

Data steps can edit fields, parse JSON, filter/sort/limit lists, merge values, format dates, or add UTM parameters. Read RSS feed fetches current feed items.

JavaScript receives input and returns a JSON value. It has a two-second deadline and a 32 MiB heap, with no network, file, or environment access. Use HTTP request for API calls.

See the API-to-post example for a short transformation.
