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

    // #!/bin/bash
    // apiKey="yourApiKey"
    // secret="yourSecret"
    // curl -i \

    //   -H 'Accept:application/json' \

    //   -H 'X-Signature:'$(echo -n ${apiKey}${secret}$(date +%s)|sha256sum|awk '{ print $1}')'' \
    //   https://api.test.hotelbeds.com/hotel-api/1.0/status
