How to Send GET Requests With cURL

How to Send GET Requests With cURL

cURL is a command-line tool and a library that allows you to transfer data to and from servers using various protocols. Besides extracting public data, which can be HTML, text, JSON, images, etc., cURL can also handle sessions and cookies. It can connect with APIs and be easily incorporated with shell commands for automation. All these cases make cURL a great tool for web scraping. 

Using a cURL GET request can help you extract public data, so we explain how to send GET requests in this article. 

What is a GET request? 

A GET request is an HTTP request used to retrieve data from a specific web page. For example, when you type in a URL into your browser and click enter, your browser sends a GET request to the server hosting that URL, requesting to retrieve the associated HTML code.

While other HTTP request methods can also result in a web server sending you HTML, those methods are meant for another purpose. For example, HTTP POST is used for posting data. So, you use HTTP POST to send data to a server. For example, the Login button sends your username and password to the server. You may still see a web page, but the POST request method was only for sending the form data. If you want to learn how to send POST requests, check out our POST requests with cURL blog post. 

On the other hand, a GET request doesn't send any data. It's used only for requesting a page or other resources, such as images. Here's a simple example of a cURL GET request:


The result is the HTML returned by the web server.

Steps of sending GET requests with cURL

Now that we've covered the basics let's delve into how to send a GET request using cURL. In this tutorial, we'll use, a simple HTTP request and response service. We'll explore different aspects of cURL, including:

  • Simple cURL GET requests

  • Sending a GET request with parameters

  • Retrieving GET HTTP headers

  • Receiving responses in JSON format

  • Following redirects

  • Sending cookies with a GET request

Step 1 - Simple cURL GET requests

If the default request method is GET, you can skip --request option and send a GET request as follows:


Step 2 - GET request with parameters

A GET request with parameters allows you to send additional data to the server within the URL of your request. cURL provides two powerful options, -d and -G, to facilitate this.

Note that if you use -d without -G, the request will be a POST request. Also, if you use the -X option with GET value, the data you want to send with -d will be ignored.

Therefore, you must use -G along with -d if you want to send parameters with a GET request.

curl -G -d "param1=value1" -d "param2=value2"

In the above command, 'param1' and 'param2' are the keys, and 'value1' and 'value2' are their respective values. The -d option can be used multiple times to send various parameters.

Alternatively, the GET parameters can be included as part of URL:

curl ''

Step 3 - GET HTTP Headers

HTTP headers allow for exchanging additional information between the client and server during an HTTP request. To get the HTTP headers along with the response body, use the -i or --include option in the curl GET command:

curl -i

This command retrieves the HTTP response headers, such as the server, date, content type, and content length. They provide useful information about the nature and specifics of the response data.

Note that the long parameter for fetching response headers is --head:

curl --head

Step 4 - Retrieve Data in JSON Format

JSON has become a standard for data exchange in the modern web development ecosystem. When interacting with APIs, requesting data in JSON format is crucial. You can instruct cURL to accept the response in JSON format by using the -H option followed by "Accept: application/json":

curl -H "Accept: application/json"

Note that sending "Accept: application/json" doesn't guarantee that the response will be returned in JSON format. It highly depends on whether the website supports returning a JSON response.

Step 5 - Follow Redirects

In certain scenarios, the URL you're requesting might redirect to another URL. By default, cURL doesn't follow such redirects, but you can explicitly instruct it to do so. You can achieve this by using the -L or --location option:

curl -L

Step 6 - Send Cookies with a GET Request

Sometimes, you may need to send cookies with your GET request, especially when interacting with websites that require user sessions or tracking user activity. You can use the -b or --cookie option followed by the name and value of the cookie:

curl -b "username=John"

cURL GET Request Arguments

To learn how to send GET requests with cURL, we've prepared a table that shows some key arguments, the short option, the long option, and the description. 

Note that you must use either the short or long option, not both.

Argument Short Option Long Option Description
-Headers -I --head Retrieves HTTP headers only.
Include Headers -i --include Includes the HTTP response headers in the output.
User Agent -A --user-agent Specifies the User-Agent string to send to the server.
Request Type -X --request Specifies the request type to use (GET, POST, PUT, DELETE, etc.)
Follow Redirects -L --location Follows redirects in the server's response.
Send Cookies -b --cookie Sends cookies from a string or file. Format of string should be NAME=VALUE; another=anotherval.
Verbose Mode -v --verbose Provides more information (debug info).
Silent Mode -s --silent Silent mode. Don't output anything.
Output to File -o --output Writes output to instead of stdout.
Pass a Custom Header -H --header Passes a custom header to the server. To get JSON, use -H "Accept: application/json".


We hope this guide helped you understand the basics of cURL GET requests. Still, as with any skill, practice is key. We recommend spending some time practicing sending requests, and you'll soon become comfortable with cURL.

Frequently asked questions

What does cURL GET do?

Simply put, a cURL GET request retrieves data from a specified resource. It sends an HTTP request to a server and gets the response body, which typically contains the webpage's content or the requested data. Optionally, you can also retrieve the response headers, which provide more details about the response, like content type, content length, server details, and more.

How do I use cURL for a GET request?

Executing a GET request using cURL is straightforward. You just need to open your terminal or command line and type curl followed by the URL you want to request. See the following example:


This command sends a GET request to the specified URL and prints the HTML code of the webpage on the terminal.

How to get data in JSON format using cURL?

First of all, you need to open your terminal or command line and type curl. You can get JSON format by using the -H and "Accept: application/json", followed by the URL you want to request. See the following example:

curl -H "Accept: application/json"
