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

# If your lambda function URL is: https://itwxyj3vd6gjtaerbfqnfccs2e0fplzh.lambda-url.us-west-2.on.aws/
# then use just the domain part here:

# Provide AWS credentials for the REST call.
