# 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.
