* This example requires 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.Rest')
loRest = CreateObject('Chilkat.Rest')

* Connect to the Amazon AWS REST server in the desired region.
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("glacier.us-west-2.amazonaws.com",lnPort,lnBTls,lnBAutoReconnect)

* Provide AWS credentials.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.AuthAws')
loAuthAws = CreateObject('Chilkat.AuthAws')
loAuthAws.AccessKey = "AWS_ACCESS_KEY"
loAuthAws.SecretKey = "AWS_SECRET_KEY"
loAuthAws.ServiceName = "glacier"
loAuthAws.Region = "us-west-2"

lnSuccess = loRest.SetAuthAws(loAuthAws)

* --------------------------------------------------------------------------
* Note: The above REST connection and setup of the AWS credentials
* can be done once.  After connecting, any number of REST calls can be made.
* The "auto reconnect" property passed to rest.Connect indicates that if
* the connection is lost, a REST method call will automatically reconnect
* if needed.

* The SNSTopic is optional.  If included, then notification is sent to the SNS topic when the job is complete.
* This example will omit the SNSTopic.

* Start an archive retrieval in for the vault named "chilkat".
