About this app

API Tester Studio is a lightweight, high-performance native mobile client handcrafted for developers, QA engineers, and system architects. Seamlessly test REST and SOAP web services, manage offline mock routes, analyze network latency, and validate JSON/XML data directly from your device.

Key Features:

Dual REST & SOAP HTTP Client

REST & Web Methods: Full support for GET, POST, PUT, DELETE, PATCH, and HEAD requests with raw or structured JSON payloads.

SOAP & XML Integration: Dispatch custom XML envelopes, configure SOAPAction headers, and inspect formatted XML responses seamlessly.

Header & Parameter Suite: Manage complex HTTP headers, custom authorization tokens, URL query parameters, and multi-part payloads.

Dynamic Environment Variables: Define and auto-resolve custom variables (e.g., {{baseUrl}}, {{token}}) across dynamic test suites.

Offline Mock Server

Local Endpoint Simulation: Register local mock endpoints that return custom JSON or XML responses with configurable HTTP status codes.

Latency Simulation: Test edge cases by introducing custom artificial response delays and timeouts.

Zero-CORS Testing: Directly simulate and debug local client responses without external internet dependency.

Request Analytics & History

Performance Telemetry: Track total API requests, average response times, and success/error ratios.

Visual Status Distribution: Inspect HTTP status codes (2xx, 4xx, 5xx) and payload distributions via interactive charts.

Developer Utility Suite

Code Snippet Generator: Convert API requests into clean, executable code snippets for cURL, Flutter/Dart, and JavaScript (Fetch).

Payload Workbench: Minify, beautify, and validate both JSON and XML data structures with real-time error highlighting.

Import & Export: Back up or share mock configurations, test suites, and request histories via clipboard or JSON export.

Disclaimer & Acceptable Use:

API Tester Studio is a software development, debugging, and network diagnostics utility. The developer disclaims all liability for unauthorized requests, heavy load execution, or disruption caused to remote endpoints. Users must have explicit permission from service owners prior to testing or dispatching requests to any live REST or SOAP infrastructure.
Test REST & SOAP APIs, run offline mock servers, and format JSON/XML payloads.
