HTTPie: Human-Friendly HTTP Client for the API Era

HTTPie is a modern command-line HTTP client that makes it simple to interact with web services. Unlike traditional tools like curl, HTTPie uses a more intuitive syntax and comes with features such as syntax highlighting, formatted JSON output, and simple commands for tasks like file uploads and authentication. Whether you're testing an API or debugging HTTP requests, HTTPie is designed to make your life easier.

Installation

HTTPie is available on multiple platforms. Here are the most common installation methods:

Using pip (Python Package Index)

If you have Python installed, you can install HTTPie with:

pip install httpie        

On macOS using Homebrew

For macOS users, Homebrew provides a quick installation route:

brew install httpie        

On Linux

Most Linux distributions offer HTTPie in their package managers. For example, on Debian/Ubuntu:

sudo apt-get install httpie        

Alternatively, using pip (recommended for the latest version):

pip install --upgrade httpie        

On Windows

For Windows users, you can install HTTPie via pip in a Command Prompt or PowerShell:

pip install httpie        

Basic Usage

HTTPie’s syntax is designed to be simple and intuitive. The general structure is:

http [METHOD] URL [ITEM [ITEM]]        

GET Request

To perform a GET request, simply run:

http GET https://httpbin.org/get        

The response should look similar to:

HTTP/1.1 200 OK
Access-Control-Allow-Credentials: true
Access-Control-Allow-Origin: *
Connection: keep-alive
Content-Length: 295
Content-Type: application/json
Date: Sat, 15 Mar 2025 16:43:06 GMT
Server: gunicorn/19.9.0

{
    "args": {},
    "headers": {
        "Accept": "*/*",
        "Accept-Encoding": "gzip, deflate",
        "Host": "httpbin.org",
        "User-Agent": "HTTPie/3.2.4",
        "X-Amzn-Trace-Id": "Root=1-67d5ae1a-311cca7e1181ebf347615f01"
    },
    "origin": "73.193.52.7",
    "url": "https://httpbin.org/get"
}        

Since GET is the default method, you can also omit it:

http https://httpbin.org/get        

POST Request

For a POST request with JSON data, you can include key-value pairs:

http POST https://httpbin.org/post name=John age:=30        

Note: The := operator is used to pass a number (or a JSON object/array) instead of a string.

Other HTTP Methods

You can specify other methods like PUT, PATCH, or DELETE in a similar way:

http PUT https://httpbin.org/put name=John age:=30
http DELETE https://httpbin.org/delete        

Sending Data

HTTPie makes it easy to send different types of data with your requests.

Sending JSON

By default, HTTPie sends data as JSON when you provide key-value pairs. For example:

http POST https://api.example.com/users username=johndoe active:=true        

This sends a JSON payload:

{
  "username": "johndoe",
  "active": true
}        

Sending Form Data

If you need to send form-encoded data, you can explicitly specify it:

http --form POST https://api.example.com/login username=johndoe password=secret        

Sending Raw Data

For raw data or when the automatic JSON detection isn’t desired, you can use the --raw flag:

http --raw POST https://api.example.com/rawdata "raw body text"        

Customizing Requests

HTTPie offers several options to customize your HTTP requests.

Custom Headers

Add headers easily by specifying the header name followed by a colon:

http GET https://httpbin.org/get 'User-Agent:HTTPie'        

Query Parameters

Simply add query parameters to the URL or as additional arguments:

http GET https://api.example.com/search q==HTTPie        

The == syntax ensures the value is sent as a query parameter without JSON encoding.

Verbosity and Debugging

For detailed output including request headers, use:

http -v GET https://httpbin.org/get        

For even more detailed debugging information, you can add multiple -v flags.

Authentication

HTTPie supports various authentication methods directly from the command line.

Basic Authentication

For basic auth, use the -a flag with username:password:

http -a username:password GET https://api.example.com/secure-endpoint        

Bearer Token

To send a bearer token, you can manually add the header:

http GET https://api.example.com/secure-endpoint 'Authorization:Bearer YOUR_TOKEN'        

There’s also support for other authentication schemes and even plugins if needed.

File Uploads and Downloads

HTTPie makes file uploads straightforward.

Uploading Files

Use the @ symbol to upload a file. For example, to upload an image:

http --form POST https://api.example.com/upload file@/path/to/image.jpg        

Downloading Files

To download a file, use the --download (or -d) flag:

http --download GET https://example.com/file.zip        

This will save the file with its original name (or you can specify a name using the --output flag).

Advanced Options and Scripting

HTTPie’s flexibility makes it ideal for scripting and automating API calls.

Saving Output

You can direct the output to a file using shell redirection:

http GET https://httpbin.org/get > response.json        

Environment Variables and Configuration

HTTPie supports configuration files that let you set default options for all your requests. Create a file at ~/.httpie/config.json and include your default settings:

{
  "default_options": ["--timeout=30"],
  "default_headers": {
    "User-Agent": "HTTPie"
  }
}        

Using with Shell Scripts

You can embed HTTPie commands within shell scripts to automate repetitive tasks. For example:

#!/bin/bash
# A simple script to check the status of an API

API_URL="https://api.example.com/status"
RESPONSE=$(http --check-status GET $API_URL)
echo "API Response:"
echo "$RESPONSE"        

Make your script executable and run it as needed.

Tips, Tricks, and Troubleshooting

Tips

  • Colorized Output: HTTPie colorizes JSON output, making it easier to read. Use --style=monokai (or another style) if you prefer a different look.
  • Aliases: Create shell aliases to shorten common commands.
  • History: Use your shell’s history and command completion features to quickly reuse frequently used commands.

Troubleshooting

  • Timeouts: If your requests are timing out, use the --timeout option to increase the limit.
  • SSL Issues: For troubleshooting SSL problems, add the --verify=no flag (use with caution).
  • Verbose Mode: When in doubt, use the -v flag to see detailed request/response data, which can help debug issues.

HTTPie streamlines the process of interacting with APIs from the command line. Its intuitive syntax, powerful features, and extensive customization options make it a great tool for developers, QA engineers, and system administrators alike. Whether you’re making simple GET requests or scripting complex interactions, HTTPie is a reliable companion in the API era.
