S3 List Buckets using an STS Session Token

See more AWS Security Token Service Examples

This is an example showing how to use an STS session token in an Amazon AWS request. This example will list S3 buckets using a previously obtained session token. Lua

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

-- See Get AWS STS Session Token for sample code to get the session token XML.

-- The purpose of this example is to show how to use the temporary AccessKeyId, SecretAccessKey, and SessionToken.
