Curl Examples For Common Use Cases

In this article I will explain how curl can be used to make HTTP requests. Just use some tools like ngrok or

curl send post request

This Python code snippet was generated automatically for the Curl POST JSON example. Those examples involve working with HTTP, the most popular protocol. Let’s dive into some of the commands and operations that you are most likely to want to perform when working with HTTP requests. I’m going to use JSON Placeholder, an awesome example site for testing API calls.

Get The Http Response Headers

Here you can also select Content-Type for your POST data. Post requests to the server and check server responses. Test Server endpoints by sending HTTP POST, GET, PUT, and HEAD requests directly from your phases of systems development life cycle browser. Create PHP, Python, Java, Curl, and JavaScript code snippets from your requests with one click. Share your HTTP requests online, showcase your work, or discuss with colleagues and friends.

You can follow along and paste all the commands into your terminal to see what response you get. I’m going to demonstrate how to do GET, POST, PUT, PATCH, and DELETE curl send post request requests via Postman and cURL. If you don’t have Postman, simply download it from the website. cURL should already be installed in your macOS or Linux environment.

Sending A Basic Email With Attachment

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.

In this example, we post data with PHP CURL. We will convert array data to JSON data using json_encode() method and then we will post data with PHP CURL. The easiest way to authenticate with Oracle Eloqua’s APIs is to use basic authentication which uses your Eloqua company name, user name, and password to authenticate. To use basic authentication, use the cURL –user option followed by your company name and user name as the value. Partially issue got resolved but still I stuck with the problem. I am giving arguments from outside while executing shell script. In below lines, i am giving organization value at the time of executing script. organization is getting created if i give argument for organization but if you see in second line, data.json also contains $organization value.

What Is Curl

To know more about curl you can check the documenation links I have provided above. In order to make the POST call, type the following command. You can check if you have Curl Installed in your System using the command. cURL is basically used to transfer data using Internet Protocols for the given URL.

You may cancel this same scheduled email by using the Cancel Scheduled Sends endpoint. Submitting such forms is a common operation with curl; effectively, to have curl fill in a web form in an automated fashion. This option makes it easy to switch between POSTing and GETing a form, for curl send post request example. This option offers several different ways to URL encode the data you give it. To know more about curl you can check the documentation links I have provided above. Encrypt authorization data on the Authorization tab. Your requests will work, but users don’t see this data.

These curl recipes show you how to send POST requests with curl. To make it send POST requests, use the -X POST command line argument. To add POST data to the request, use the -d argument. To change the Content-Type header that tells the web server what type of data you’re sending, use the -H argument.


It usually sends a chunk of relatively small amounts of data to the receiver. To send a GET request to the server, simply enter your URL, select the GET method from the dropdown list, and click Send. If your software development process request requires authorization, enter your credentials on the Authorization tab. To make a POST request online, select the POST method from the dropdown list and enter the POST data on the Content tab.

curl send post request

The authorization header will be automatically generated when you send the request. The verbose result has details like status code, Content Type, Content Length and so on.

Get Request With Curl

This recipe skips the -X POST argument because -d argument forces curl to make a POST request. curl is a a command line tool that allows to transfer data across the network. One example of when this can happen is when you send a large file over HTTP, only to discover that the server requires authentication and immediately sends back a 401 response code. Browse other questions tagged php curl or ask your own question. This will read the contents of the file named filename.txt and send it as the post request. In this tutorial, we have discussed how to make POST requests and pass data in various formats.

  • The data sent using a POST request is mainly stored in the request body of the HTTP request.
  • I am giving arguments from outside while executing shell script.
  • When -d is used, curl implicitly sets the request’s type to POST.
  • You can also check out some interesting specific uses of the curl command here.
  • Here are a few cURL argument we’ll pass with our requests.
  • I am a full-stack developer, entrepreneur, and owner of
  • As usual, if you are already familiar with this, you can feel free to skip ahead; otherwise, stick around.

The curl project has a curl command line and also a libcurl library. In this article we will be focussing on the curl command line. I don’t konw how to post data also with payload image data.

Alter Xml Schema Collection Transact

It also provides features such as user-authentication, proxy tunneling, download resume, form-based uploads, SSL certificates, and so much more. It is safe to say that cURL is more than an HTTP client. A third option is, of course, to use a network capture tool such as Wireshark to check exactly what is sent over the wire. See the Wireshark documentation for details on doing that.

curl send post request

but arguments/variables which I am passing at the time of script is not passing to data.jason file and it is taking value as “$organization”. Similar to the previous recipe, this recipe uses the -F argument to upload a binary file (a photo with the filename photo.png) via a multipart POST request. It also specifies the MIME type different agile methodologies of this file and sets it to image/png. If no type is specified, then curl sets it to application/octet-stream. In this recipe, we skip the -X POST argument that explicitly tells curl to send a POST request. We can skip it because we have specified the -d argument. When -d is used, curl implicitly sets the request’s type to POST.

Send A Post Request With Form Data

You can send additional fields with the help of the -d flag and coupling it with the POST request you send to the server. The following POST call sends a user and a transfer area together Setup CI infra to run DevTools with the critical parameters. POST is the HTTP method that was invented to send data to a receiving web application, and it is how most common HTML forms on the web works.

It can be used to get a better idea of what happened during the HTTP request. This endpoint accepts a query parameter called name. libcurl is a free, client-side URL transfer library with support for a wide range of protocols. libcurl is portable, thread-safe, feature rich, and well supported on virtually any platform. It is probably the most popular C-based, multi-platform file transfer library in use.

You can use the -H flag to send a piece of data or a header with a curl. The command that follows sends a JSON object with a request. If you want to submit a form with curl and make it look as if it has been done with a browser, it is important to provide all the input fields from the form. A common method for web pages is to set a few hidden input fields to the form and have them assigned values directly tuckman stages of team development in the HTML. We’ll keep things fairly simple and show three examples to make a POST request with curl from the command line, with syntax with and without data, and also to a form. Curl is the powerful command line utility that allows you to transfer data to or from a server or URL. One common function used by developers is to make a POST request with curl, which is what we’re going to cover here.
