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.
