Ultimate Guide: How to use API Request Tester
Our API Request Tester is a lightweight, browser-based alternative to heavy desktop clients like Postman or Insomnia. It allows developers to quickly construct and execute HTTP requests to REST APIs without leaving their web browser.
Complete Request Control
- Methods: Support for all standard HTTP methods (GET, POST, PUT, DELETE, PATCH, OPTIONS).
- Headers: Easily add custom authorization tokens, content types, and accept headers.
- Body Payload: Send JSON, form data, or raw text payloads with syntax highlighting.
- Response Inspection: View formatted JSON responses, HTTP status codes, and response times instantly.
Why use a browser-based tester?
When you are reading API documentation or debugging a webhook, opening a separate heavy application breaks your workflow. Our tool loads instantly and handles CORS-enabled API requests directly from your tab, making quick tests frictionless.
Frequently Asked Questions
QWhy am I getting a CORS error?
Because the request is made directly from your browser, the target API must have CORS (Cross-Origin Resource Sharing) enabled for external origins. If it doesn't, the browser will block the request for security reasons.
QAre my API keys stored?
No. All requests are dispatched directly from your browser to the target server. We do not intercept, log, or store any headers, payloads, or API keys.
