Install cURL

The cURL command-line tool is used to demonstrate the REST API examples in this guide. To connect securely to the server, you must install a version of cURL that supports SSL, if not already installed.

To check if cURL is already installed on your system, launch a terminal and enter the command curl.

To install cURL on your system:

  1. In your browser, navigate to the cURL home page at and click Download in the navigation menu.

  2. On the cURL Releases and Downloads page, locate the SSL-enabled version of the cURL software that corresponds to your operating system. Click the link to download the ZIP file, and extract the executable to the desired folder.

When running cURL from a Windows command shell only, you must provide an SSL certificate authority (CA) file or bundle to authenticate against the Verisign CS certificate.

  1. Navigate to the cURL CA Extract page at and download the cacert.pem SSL CA certificate file in the folder where you installed cURL.

  2. Open a command window, navigate to the directory where you installed cURL, and set the cURL environment variable, CURL_CA_BUNDLE, to the location of the SSL CA certificate file. For example, on a Windows system you would enter:

    C:\curl> set CURL_CA_BUNDLE=cacert.pem

If your network requires you to connect to Oracle Cloud through a proxy server, choose one of these options to specify the location of the proxy:

  • Set the HTTP_PROXY or HTTPS_PROXY environment variables prior to running cURL.

  • Use the -x option in cURL.

You are now ready to send REST requests to Oracle Cloud Stack Manager using cURL. For general information about using cURL see Use cURL.
