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

// This example duplicates the following CURL statement provided in the hotelbeds.com "Getting Started"
// developer documentation:

// #!/bin/bash 
// apiKey="yourApiKey"
// secret="yourSecret"
// curl -i \
//   -X GET \
//   -H 'Accept:application/json' \
//   -H 'Api-key:'$apiKey'' \
//   -H 'X-Signature:'$(echo -n ${apiKey}${secret}$(date +%s)|sha256sum|awk '{ print $1}')'' \
//   https://api.test.hotelbeds.com/hotel-api/1.0/status

// The "date + %s" command emits a UNIX date/time number such as 1605548842
// We need to concatenate the apiKey, secret, and current date/time in UNIX (numeric) time format.
