# HTTP Request Tester A lightweight in-browser HTTP client (mini Postman): send GET/POST/PUT/DELETE requests with custom headers and body, inspect status, headers, timing, and formatted response — all from your browser > Canonical page: https://elysiatools.com/en/tools/http-request-tester - **Category:** Development - **Keywords:** http, http client, api tester, postman, rest client, request, fetch, curl, endpoint tester, api request, http test ## Overview The HTTP Request Tester is a lightweight, in-browser HTTP client that allows you to send GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS requests directly from your browser. Without installing heavy desktop applications, you can customize headers, configure request bodies, toggle redirect behaviors, and inspect status codes, response headers, timing data, and formatted payloads instantly. ## Inputs - **URL** (text): https://api.example.com/endpoint - **HTTP Method** (select) - **Headers** (textarea): Authorization: Bearer token Accept: application/json - **Body** (textarea): { "key": "value" } - **Body Type** (select) - **Follow Redirects** (checkbox) - **Show Response Timing** (checkbox) ## When to use - When you need to quickly test a REST API endpoint without opening heavy desktop software. - When debugging webhooks or backend APIs by sending custom HTTP methods, headers, and payloads. - When verifying API response times, status codes, and headers directly from your web browser. ## How it works - Enter the target API endpoint URL and select the desired HTTP method such as GET, POST, or PUT. - Add custom headers and configure the request body type (JSON, Form, or Raw) if your request requires a payload. - Click send to execute the request and view the formatted response, status code, headers, and timing metrics. ## Use cases - Testing a local or public REST API endpoint to verify JSON responses. - Sending a POST request with a JSON payload to test a database insertion endpoint. - Checking HTTP response headers and status codes for debugging server configurations. ## Frequently asked questions ### Does this tool send requests from my browser or a backend server? Requests are sent directly from your browser using standard web APIs, meaning local network endpoints are accessible but subject to CORS policies. ### Can I send custom headers like Authorization tokens? Yes, you can input custom headers line-by-line in the Headers field, such as 'Authorization: Bearer token'. ### What request body formats are supported? The tool supports Raw text, JSON, and Form (x-www-form-urlencoded) body types. ### Can I measure how long an API request takes? Yes, by enabling the 'Show Response Timing' option, the tool displays the duration of the request. ### Does the tool follow HTTP redirects automatically? Yes, you can toggle the 'Follow Redirects' option to control whether the client automatically follows HTTP redirects. ## Related tools - [WebSocket Tester](https://elysiatools.com/en/tools/websocket-tester): Connect to any WebSocket (ws:// or wss://) endpoint from your browser, send and receive messages, and inspect open/close/error events with codes — ideal for debugging real-time APIs and sockets - [GraphQL Playground](https://elysiatools.com/en/tools/graphql-playground): An in-browser GraphQL client: write queries and variables, send them to any GraphQL endpoint, and inspect formatted JSON results or error arrays — perfect for iterating on schemas during development - [HTTP Headers Analyzer](https://elysiatools.com/en/tools/http-headers-analyzer): Analyze HTTP headers, security configurations, and response information - [Tailwind Color Palette Sync](https://elysiatools.com/en/tools/tailwind-color-palette-sync): Generate theme.extend.colors for tailwind.config.ts from HEX colors, with WCAG contrast levels and optional dark mode. - [API Contract Mutation Tester](https://elysiatools.com/en/tools/api-contract-mutation-tester): Mutate OpenAPI request fields into semantically risky variants and optionally send them to a real backend to check defensive validation coverage - [API Contract Stress Tester](https://elysiatools.com/en/tools/api-contract-stress-tester): Generate boundary-value test cases from an OpenAPI 3.x document and optionally send them to a real backend to spot contract mismatches - [Cron Expression Explainer](https://elysiatools.com/en/tools/cron-expression-explainer): Parse a 5-part / 6-part / Quartz cron expression into a plain-language schedule description, show the field-by-field breakdown, and list the next N execution times in any IANA timezone — with an AI-generated natural-language explanation in your language - [cURL to Go (net/http) Converter](https://elysiatools.com/en/tools/curl-to-go): Convert a cURL command into a Go net/http code snippet with http.NewRequest, headers, and body ## Samples - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion - [Android Image Processing Java Samples](https://elysiatools.com/en/samples/android-image-processing-java): Android Java image processing examples including reading/saving images, scaling, and format conversion - [Android Image Processing Kotlin Samples](https://elysiatools.com/en/samples/android-image-processing-kotlin): Android Kotlin image processing examples including reading/saving images, scaling, and format conversion - [Web Image Processing Rust Samples](https://elysiatools.com/en/samples/web-image-processing-rust): Web Rust image processing examples including image read/save, scaling, and format conversion ## Related content - [cURL to Code Converter and HTTP Request Tools](https://elysiatools.com/en/hubs/curl-to-code-converter): Convert cURL commands into Go, JavaScript, Python, PHP, and HAR, generate API request snippets, test HTTP requests, and look up status codes in one focused developer hub. - [Audio Encoding and Format Conversion Tools](https://elysiatools.com/en/hubs/audio-convert): Compare audio format conversion, bitrate changes, sample-rate conversion, codec swaps, and export tools in one hub for delivery and archive workflows. - [Image Format Conversion and Animated Export Tools](https://elysiatools.com/en/hubs/image-convert): Compare image format converters for JPG, PNG, GIF, AVIF, WebP, TIFF, ICO, base64, and animation-friendly exports in one hub. - [JSON Interchange and Format Translation Tools](https://elysiatools.com/en/hubs/json-convert): Compare JSON conversion tools for CSV, YAML, TOML, GraphQL, XML, Markdown, Excel, BSON, EDN, and related structured formats in one hub.
