The HTTP Request node is the foundational building block for invoking microservice APIs, external webhooks, and third-party SaaS endpoints on the Quixa canvas.

1. Node Types & Creation

Quixa provides two ways to work with HTTP requests:
  • Collection-Bound Endpoints: Dragged directly from your imported OpenAPI/Swagger specifications in the left sidebar. Retains schema definitions and validation contracts.
  • Standalone HTTP Request ([ ⚡ qComponent ]): Placed from the component palette. Operates independently without requiring a parent OpenAPI specification.
Both node types support the Swagger UI color standard:
  • GET: #61affe (Blue)
  • POST: #49cc90 (Green)
  • PUT: #fca130 (Orange)
  • DELETE: #f93e3e (Red)
  • PATCH: #50e3c2 (Teal)

2. Unified Request Bar

Double-clicking any HTTP node opens the configuration dialog featuring a Unified Top Request Bar that remains persistent across all tab views:
  1. HTTP Method Selector: Switch between GET, POST, PUT, DELETE, PATCH, OPTIONS, and HEAD.
  2. Endpoint URL Input: Supports dynamic variables and path parameter syntax (e.g. https://api.acme.com/v1/users/{userId}).
  3. Save & Test Actions: Save node settings or perform immediate test execution to verify credentials.

3. Path Parameters & Bidirectional Auto-Sync

When configuring URLs with path placeholders:
  • Typing {petId} into the URL input automatically creates a corresponding row in the Params tab with Location = path.
  • Renaming or removing the placeholder updates the URL and params table bidirectionally without manual coordination.
  • The backend execution engine substitutes {petId} at runtime using mapped variables or predecessor bindings:

4. Comprehensive Authorization Engine

Standalone HTTP nodes feature an inline Authorization Form supporting modern enterprise auth standards:

5. Body Payloads & Dynamic Template Bindings

The Body tab supports:
  • JSON: Syntax-highlighted Monaco editor with dynamic variable completion.
  • x-www-form-urlencoded: Form key-value editor.
  • multipart/form-data: File upload attachments and binary buffers.
  • Raw / Text: Plain text or XML payloads.
Dynamic variable bindings are evaluated at runtime using mustache syntax:
