A standardized solution for building API's so that external clients can
communicate with Backdrop.


  • Create a unified Backdrop API for web services to be exposed in a variety of
    different server formats.
  • Provide a service browser to be able to test methods.
  • Allow distribution of API keys for developer access.

Once downloaded you need to add spyc.php to the rest_server/lib folder which exists under
the location you have installed services in.
