Instead of hand-writing HTTP calls and getting the syntax wrong, this tool lets you compose a request visually and then hands you production-ready code. Every header, query parameter, and body field you fill in is converted into an idiomatic snippet in the language you pick. The flow is straightforward:
This tool fits two common workflows. The first is rapid integration: you need a fetch call in a web app, a requests call in a Python script, or a cURL command to verify something in the terminal, and you want them generated correctly the first time rather than transcribed from memory. The visual form prevents the classic mistakes, like forgetting the Content-Type header or failing to stringify a JSON body in fetch.
The second workflow is exploring authentication. Because the builder supports Basic Auth, Bearer tokens, and API key headers, you can prototype how a protected endpoint behaves with each credential type before committing the logic to code. That is valuable when a service supports several auth methods and you want to compare behavior without editing code between attempts. Teams spread across different stacks benefit too, since one visual configuration can be exported as JavaScript, Python, Go, or Rust to match each developer's environment.
When you build a request that carries a Bearer token or an API key, that credential becomes part of the generated code you copy into your project. If the builder ran on a remote server, every token you entered could be captured in its logs. This tool performs all request construction and code generation locally in your browser, so the credentials you type never travel anywhere.
That is especially important for developers working with production tokens or shared service accounts. Generating authenticated code snippets without a single credential leaving the device means you can paste a real token into the form, copy out working code, and be confident that no third party recorded either the token or the endpoint it was meant for.
Fill in the URL, select HTTP method, add headers, query parameters, and request body using the visual form fields.
Choose from Basic Auth, Bearer Token, or API Key authentication methods and enter your credentials.
Pick your desired output language — JavaScript fetch, axios, Python requests, cURL, Go, or Rust.

Practical examples to help you get the most out of Request Builder:
fetch('https://api.example.com/data', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer eyJhbGciOiJIUzI1NiIs...'
},
body: JSON.stringify({
name: 'John Doe',
email: 'john@example.com'
})
})import requests
url = 'https://api.example.com/data'
headers = {
'Content-Type': 'application/json',
'Authorization': 'Bearer eyJhbGciOiJIUzI1NiIs...'
}
data = {
'name': 'John Doe',
'email': 'john@example.com'
}
response = requests.post(url, headers=headers, json=data)When sending POST, PUT, or PATCH requests with a JSON body, always include Content-Type: application/json. Without it, the server may not parse the body correctly.
The fetch API requires the body to be a string for JSON payloads. Use JSON.stringify() to convert your JavaScript object before passing it as the body parameter.
JavaScript (fetch, axios), Python (requests), cURL, Go, and Rust are currently supported. More languages are planned.
Yes. Add custom headers, query parameters, and request body. Auth options include Basic Auth, Bearer Token, and API Key headers.
Fill in the URL, select the HTTP method, add headers and body using form fields. The tool generates ready-to-use code snippets in your chosen language.
No. All request building and code generation happens locally in your browser.
Build requests with form fields for URL, method, headers, body, and params.
Generate code for fetch, axios, curl, Python requests, and more.
Basic auth, Bearer token, API key header generation.
Copy generated code snippets directly to clipboard.
Request Builder is useful in a variety of scenarios across different workflows:
Generate fetch or axios code snippets for quick integration into web apps
Build authenticated API requests with Bearer tokens or API keys
Convert visual request configurations into production-ready code
Use the multi-language export to generate code in JavaScript, Python, Go, and Rust — perfect for teams using different stacks.
Build requests with different auth types (Basic, Bearer, API Key) visually before committing to code implementation.
