* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.
loHttp = CreateObject('Chilkat.Http')
* Implements the following CURL command:
* curl "https://pay-api.amazon.com/:version/checkoutSessions/:checkoutSessionId/complete" \
* -X POST
* -H "authorization:Px2e5oHhQZ88vVhc0DO%2FsShHj8MDDg%3DEXAMPLESIGNATURE"

* Note: When the private key is provided as shown above, Chilkat will automatically add the required x-amz-pay-* headers to the HTTP request,
