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

loRest = CreateObject('Chilkat_9_5_0.Rest')

loAuthAws = CreateObject('Chilkat_9_5_0.AuthAws')

* Don't forget to change the region to your particular region. (Also make the same change in the call to Connect below.)
loAuthAws.Region = "us-west-2"
loAuthAws.ServiceName = "kms"
* SetAuthAws causes Chilkat to automatically add the following headers: Authorization, X-Amz-Date
loRest.SetAuthAws(loAuthAws)

* URL: https://kms.us-west-2.amazonaws.com/
* Use the same region as specified above.
lnSuccess = loRest.Connect("kms.us-west-2.amazonaws.com",443,1,1)
