Installing cURL on Windows for Slack Notifications

Do the following steps to install cURL on a Windows OS.  I mainly use cURL on Windows Servers to notify me of certain events via API.

Installing cURL

• Download cURL
  • Make sure to download the one from: Viktor Szakats
  • Extract the contents to: c:\curl
• Download the cacert.pem
  • Extract this to where curl.exe is located. Typically, this is located in c:\curl\bin
  • Rename this file to: curl-ca-bundle.crt

Add as Environment Variable
