AddToContextAction

Purpose Adds one or more computed values to the API runtime context (this), making them available to later actions. Use it to define temporary or derived variables such as totals, flags, or enriched fields.

When to use it

• After parameter transformations

• Before CRUD operations (e.g., injecting computed fields)

• Before response shaping

Key fields

Example

{
  "id": "a60-add-context",
  "extendClassName": "AddToContextAction",
  "name": "addComputedContext",
  "context": [
    { "contextName": "discountRate", "contextValue": "this.customer?.isVip ? 0.2 : 0.0" },
    { "contextName": "grandTotal", "contextValue": "this.invoiceTotal * (1 - this.discountRate)" }
  ]
}

After execution, this.discountRate and this.grandTotal become available for later steps.
