Installing cURL Command Line Tool on Windows – Oracle
Installing the cURL Command-Line Tool on Windows
This tutorial shows you how to access Oracle Messaging Cloud
Service via the REST interface by using the cURL command-line tool. cURL is free, open software that runs under various operating systems.
This tutorial demonstrates cURL on a Windows 64-bit
operating system that is enabled for the secure sockets layer (SSL). The authentication aspects of the Messaging
Cloud Service require an SSL-enabled environment.
Your first task is to install the appropriate version of cURL
for your SSL-enabled environment.
There is an ordered series of steps to follow to install cURL
on Windows. There are two libraries to install and they must
be installed before cURL will work with SSL. Also, they must be
installed in this order to work. Do not skip
the step to install a recent certificate.
In your browser, navigate to the cURL welcome page at and
click Download.
On the cURL Releases and Downloads page, click the link for the SSL-enabled version for your computer’s operating system, download the zip file, and install
it in a new folder on your computer.
The cURL website offers a wizard to find the appropriate version for your
computer’s operating system.
For this tutorial, the 64-bit generic, SSL-enabled version for Windows is selected.
Install recent CA Certificates. Do not skip this step.
Download, a recent copy of valid CERT
files, from
Copy it to the same folder where you placed
and rename it
Invoke from a command window (in Windows, click Start > Run and then enter “cmd” in the Run dialog box).
You can enter curl –help to see a list of cURL commands.
Installing and using cURL | Zendesk Developer Docs
All the examples in the Zendesk REST API docs use cURL, a lightweight, command-line tool for making HTTP requests without a web browser. cURL lets you try out various API requests in a command-line interface such as the command prompt in Windows or Terminal in macOS. You don’t need to build a working web application just to try out the APIs.
cURL makes HTTP requests just like a web browser. To request a web page from the command line, type curl followed by the site’s URL:
The web server’s response is displayed directly in your command-line interface. If you requested an HTML page, you get the page source — which is what a browser normally sees.

Using cURL
You can use cURL to inspect and test different Zendesk API requests without having to build a functioning web application. For example, the following cURL statement makes an HTTP request to the List Groups endpoint in the Zendesk API:
curl \ -v -u [email protected]:mypassword
The API returns a JSON object that lists the groups in your Zendesk Support instance:
{ “groups”: [ { “name”: “DJs”, “created_at”: “2009-05-13T00:07:08Z”, “updated_at”: “2011-07-22T00:11:12Z”, “id”: 211}, { “name”: “MCs”, “created_at”: “2009-08-26T00:07:08Z”, “updated_at”: “2010-05-13T00:07:08Z”, “id”: 122}]}
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It’s designed to be easy for humans to read and write, and for machines to parse and generate. To learn more, see Working with JSON.
Using cURL in Windows
You can use the Windows command prompt to run the cURL examples. To start the command prompt, open the Start menu, type cmd in the search box, and press Enter.
Note: Windows 10 users can install and use a Bash shell, a Unix command-line interface that’s the same as the one in macOS. See Setting up a Bash shell in Windows 10 in this Help Center. If you use this option, ignore all the instructions for Windows users in this article.
cURL isn’t installed in Windows by default. See Installing cURL below to install it on your system.
The examples in the docs have to be modified slightly to work correctly in Windows. First, replace any line-ending backslash (\) character with the caret (^) character. Second, if an example contains JSON data, move the data to a file before running the example. The following sections give more details.
Replace line-ending backslashes
The cURL examples often have a backslash (\) at the end of lines to break up a long statement into easier-to-read lines. The backslash is a line continuation character in UNIX but not in Windows. In Windows, replace any backslash at the end of lines with the caret (^) character, which is an escape character in Windows. Don’t leave any space after any ^ character or it won’t work. The caret will escape the space instead of the new line.
Example:
curl ^ -v -u [email protected]:mypassword
You can paste a multiline statement at the command prompt by clicking the icon in the upper-left corner and selecting Edit > Paste. If you prefer using the keyboard, press Alt+spacebar to open the menu, then press E and P.
Move JSON data to a file
The Windows command prompt doesn’t support single quotes. It’s a problem because cURL statements use single quotes to specify JSON data. Example:
curl {subdomain}. ^ -d ‘{“group”: {“name”: “My Group”}}’ ^ -H “Content-Type: application/json” ^ -v -u {email_address}:{password} -X POST
The statement specifies JSON data for creating a group (the -d flag stands for data). Because the JSON is enclosed in single quotes, the statement won’t work on the command line.
To fix the problem, save the JSON in a separate file and import it into the cURL statement. To modify the example above, create a file named containing the following text:
{“group”: {“name”: “My Group”}}
Next, change the cURL statement to import the JSON data with the @filename syntax:
curl {subdomain}. ^ -d ^ -H “Content-Type: application/json” ^ -v -u {email_address}:{password} -X POST
Before running the statement, use the cd command (for change directory) to navigate to the folder that contains the file. Example:
C:\> cd json_files
Then paste the cURL statement at the command prompt:
An alternative to moving the JSON to a separate file is to use double quotes around the JSON data in the cURL statement and escape the inner ones with backslashes:
-d “{\”group\””: {\””name\””: \””My Group\””}}”” \
