cURL request

You can use the command line tool cURL to send requests to the API.

Sample request

curl -H "Host: providerhostname" \
    -H "Connection: keep-alive" \
    -H "Content-Length: XXX" \
    -H "Cache-Control: no-cache" \
    -H "Origin: XXXXXXXXXXXXX" \
    -H "User-Agent: Provider User-Agent name" \
    -H "Content-Type: text/xml;charset=UTF-8" \
    -H "Accept: */*" \
    -H "Accept-Encoding: gzip,deflate" \
    -H "Authorization: Basic XxXxXxXxXxXx=" \
    --http1.1 \
    -d @messagebody.xml -X POST \ 'https://(secure)-supply-xml.booking.com/hotels/{ota or xml}/{API name}'

Here, XxXxXxXxXxXx is the machine username and password provided by Booking.com, combined into a string username:password which is then encoded using the RFC2045-MIME variant of Base64 (though not limited to 76 characters per line).

Replace the endpoint name according to the specification of the API to be called.
