' Implements the following CURL command:

' curl "https://pay-api.amazon.com/:version/checkoutSessions/:checkoutSessionId"
'   -X GET
'   -H "authorization:Px2e5oHhQZ88vVhc0DO%2FsShHj8MDDg%3DEXAMPLESIGNATURE"
'   -H "x-amz-pay-date:20201012T235046Z"

' Use the following online tool to generate HTTP code from a CURL command
' Convert a cURL Command to HTTP Source Code

' Load your Amazon Pay private key.  
' There are many other ways to load private keys into the Chilkat private key object, such as from different formats,
' or from in-memory strings or bytes.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.PrivateKey")
