* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* Implements the following POST:

* POST /:version/deliveryTrackers HTTP/1.1
* Host: pay-api.amazon.com
* Accept: application/json
* Authorization: AMZN-PAY-RSASSA-PSS PublicKeyId=f4fc06fc-c5a7-11e7-abc4-cec278b6b50a, SignedHeaders=content-type;x-amz-pay-date, Signature=4164128ec5d1b9da1700167ab2ccda8125f472c8bb9de447cebf5d741ee317c8

*     "trackingNumber" : "1Z999AA10123456784",
*     "carrierCode" : "UPS"
*   }]
* }

* The following JSON is sent in the request body.

* {
*     "amazonOrderReferenceId" : "P00-0000000-0000000",
*     "deliveryDetails" : [{
*     "trackingNumber" : "1Z999AA10123456784",
*     "carrierCode" : "UPS"
*   }]
* }

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateString("amazonOrderReferenceId","P00-0000000-0000000")
loJson.UpdateString("deliveryDetails[0].trackingNumber","1Z999AA10123456784")
loJson.UpdateString("deliveryDetails[0].carrierCode","UPS")

* 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')
loPrivKey = CreateObject('Chilkat.PrivateKey')
lnSuccess = loPrivKey.LoadPemFile("C:/someDir/myAmazonPayPrivateKey.pem")
IF (lnSuccess = 0) THEN
    ? loPrivKey.LastErrorText
    RELEASE loHttp
    RELEASE loJson
    RELEASE loPrivKey
    CANCEL
ENDIF

* 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
lcPublicKeyId = "SANDBOX-AHEGSJCM3L2S637RBGABLAFW"
lnSuccess = loHttp.SetAuthPrivateKey(lcPublicKeyId,loPrivKey)
IF (lnSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loJson
    RELEASE loPrivKey
    CANCEL
ENDIF

* 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
* x-amz-pay-idempotency-key
* Authorization

loHttp.Accept = "application/json"

* To use the live system, replace "sandbox" with "live" in the URL passed to PostJson3.
* Also, make sure to use the correct region: pay-api.amazon.com, pay-api.amazon.eu, or pay-api.amazon.jp
