Chain transformers - Alumio Documentation

Runs a list of data transformers one after another, passing the result of each step into the next. Use this when you want to group several transformation steps into one and have them apply in a fixed order, for example first setting a status and then building a label from the values you just set. It is also handy as a single building block you can drop into a feature that only lets you pick one transformer but where you actually need several.

Sample data

This example runs two steps in sequence. The first sets a status, and the second builds a label from values already on the item using the placeholders &{sku} and &{currency}. See Placeholders for the placeholder syntax.

Field	Value
Data transformers	Set values (`status` = `active`), then Set values (`label` = `&{sku} (&{currency})`)

Input:

{
    "sku": "WS-001",
    "price": 100,
    "currency": "EUR"
}

Output:

{
    "sku": "WS-001",
    "price": 100,
    "currency": "EUR",
    "status": "active",
    "label": "WS-001 (EUR)"
}
