// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')

// 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"

// 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,
