Map Keys
Reshape the payload: each row defines a new key from a {{ }} value template — outputKey → {{value}}. Use it to flatten nested data so downstream nodes read it cleanly.

Configuration
| Parameter | Type | Default | Description |
|---|---|---|---|
mappings |
key-value pairs | — | Rows of outputKey → {{value template}}. The left side is the new key name; the right side is a {{ }} expression (with the variable picker). A single {{path}} keeps the real value type; e.g. latitude → {{response.latitude}} lifts a nested value to a top-level {{latitude}}. |
passthrough |
boolean | true |
When true, unmapped keys are included in the output. When false, only explicitly mapped keys appear. |
Output Payload
The output payload carries each configured output key, resolved from its {{ }} template; unmapped keys are passed through or dropped depending on the passthrough setting.
