Any HTTP client can be used as a RESTful client. Even the BUI can return RESTful API GET results by typing in a resource URL. Mozilla Firefox has a RESTful client module that can be installed to make RESTful requests (https://addons.mozilla.org/en-us/firefox/addon/restclient/). This module allows PUT, POST, and DELETE requests as well as the normal HTTP GET requests.
RESTful clients must use TLS protocols because the SSLv2/3 protocols are no longer supported. Curl clients must use curl version 7.34.0 or higher.
This section contains more detailed information about various RESTful clients.
