Use cURL

The examples within this document use cURL to demonstrate how to access the Offline Mediation Controller REST API.

Task 1: Install cURL

To connect securely to the server, you must install a version of cURL that supports SSL and provide an SSL certificate authority (CA) certificate file or bundle to authenticate against the CA certificate store, such as Verisign.

The following procedure demonstrates how to install cURL on a Windows 64-bit system:

In your browser, navigate to the cURL Releases and Downloads page at https://curl.se/download.html.
Locate the version of the cURL software that corresponds to your operating system, click the link to download the ZIP file, and then install the software.
Go to the cURL CA Certificates Extracted from Mozilla page at https://curl.se/docs/caextract.html.
Download the cacert.pem CA certificate bundle and then copy it to the folder in which you installed cURL.

Task 2: Set Environment Variable for cURL

In a command window, set the cURL environment variable, CURL_CA_BUNDLE, to the location of your local CA certificate bundle. For example:

C:\curl> set CURL_CA_BUNDLE=cacert.pem

For information about CA certificate verification using cURL, see https://curl.se/docs/sslcerts.html.

Task 3: Start cURL

Start cURL and specify one or more of the command-line options defined in the following table:

cURL Option	Description
`-d @filename.json --data @filename.json`	Identifies the file that contains the request body, in JSON format, on the local machine. Alternatively, you can pass the request body with `-d "{id=5,status='OK'}"`.
`-H --header`	Defines content type of the request document.
`-i --include`	Displays header information in the response.
`-X method --request method`	Indicates the type of request method (for example, GET or POST).
