What HTTP methods are supported?

This tool supports all standard HTTP methods: GET (retrieve data), POST (create data), PUT (update/replace data), PATCH (partial update), DELETE (remove data), HEAD (headers only), and OPTIONS (check allowed methods). Each method is color-coded for easy identification.

Can I add custom headers?

Yes, you can add unlimited custom headers with key-value pairs. Common headers include Authorization (for API keys/tokens), Content-Type (for request body format), Accept (for response format), and custom headers specific to your API. Headers can be toggled on/off without deleting them.

How do I send a JSON request body?

Switch to the Body tab and enter your JSON payload. Make sure the Content-Type header is set to 'application/json'. The tool will send the body with POST, PUT, and PATCH requests. GET, HEAD, and DELETE requests typically don't include a body.

What response information is shown?

The tool displays: HTTP status code and text, response time in milliseconds, response size in bytes/KB/MB, content type (JSON/text), all response headers with copy buttons, and the formatted response body. JSON responses are automatically pretty-printed.

Is my request data stored?

Request history is stored only in your browser's local storage for convenience. No data is sent to or stored on our servers beyond what's necessary to proxy the request. The proxy is needed to bypass CORS restrictions that browsers enforce.
