Data Mapping & Variable Expressions

Data flow in Quixa is driven by a flexible expression engine that passes parameters, authentication credentials, and response payloads seamlessly down the execution graph.

1. Mustache Binding Syntax

Reference any predecessor node output using double-curly syntax:

{{<NodeNameOrAlias>.<PropertyPath>}}

Common Binding Patterns:

JSON Body Values: {{CreateUser.response.body.id}}
Nested Object Arrays: {{GetOrders.response.body.items[0].sku}}
Response Headers: {{Login.response.headers.x-auth-token}}
HTTP Status Code: {{PaymentStep.statusCode}}
Round-trip Latency: {{SearchApi.responseTimeMs}}

When editing URLs, Headers, or JSON Bodies, typing {{ opens the IntelliSense Autocomplete Picker, displaying all available upstream outputs with live schema previews.

2. Built-in Dynamic Generators

Inject synthetic data and dynamic timestamps directly into your payloads without writing code:

Macro	Output Example	Description
`{{$guid}}` / `{{$uuid}}`	`4a3b8d12-6f1a-4c28-912b-3e5f2a1b9c7d`	Version 4 RFC UUID
`{{$timestamp}}`	`1732284000`	Current Unix epoch in seconds
`{{$isoTimestamp}}`	`2026-10-16T14:10:00Z`	ISO-8601 UTC timestamp
`{{$randomInt}}`	`842`	Random integer (0-1000)
`{{$randomEmail}}`	`user_8492@example.com`	Synthetic user email
`{{$randomFirstName}}`	`Sarah`	Synthetic first name

3. Scoped Variables

Environment Variables: {{env.BASE_URL}}, {{env.API_SECRET}} — scoped to active deployment environments (Dev, Staging, Prod).
Flow Variables: {{flowVars.batchId}} — centralized key-values defined at the root of the workflow.
Loop Context: {{forNode.item}}, {{forNode.index}} — dynamically populated during iteration cycles.

4. Script Nodes (JavaScript Transformations)

When complex transformations, hash calculations, or custom data restructuring is required, place a Script Node:

// Script Node executes in a secure V8 VM sandbox
const rawItems = context.FetchProducts.response.body.products;

// Filter in-stock items and calculate subtotal
const inStock = rawItems.filter(item => item.inventory > 0);
const subtotal = inStock.reduce((acc, curr) => acc + curr.price, 0);

return {
  validProducts: inStock,
  totalAmount: subtotal,
  itemCount: inStock.length
};

Outputs returned from a Script Node are immediately available to subsequent nodes via {{MyScript.response.body.totalAmount}}.
