* 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/charges/:chargeId"
*  -H "authorization:Px2e5oHhQZ88vVhc0DO%2FsShHj8MDDg%3DEXAMPLESIGNATURE"
*  -H "x-amz-pay-date:20201012T235046Z"
*  -X GET

* 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.

* Provide your Amazon Pay private key and Public Key ID 
* Use your public key ID here.  It must be the one associated with the private key.
* Note: The SetAuthPrivateKey method was added in Chilkat v9.5.0.89

* Note: When the private key is provided as shown above, Chilkat will automatically add the required x-amz-pay-* headers to the HTTP request,
* and will also sign the request.  Nothing more is needed.
* Chilkat automatically generates and adds the following headers:
* 
* x-amz-pay-date
* x-amz-pay-host
* x-amz-pay-region
* Authorization
