The REST Administration API enables Oracle Application Express instance administrator to perform administrative functions in an Application Express instance over REST and HTTP protocols. This is particularly useful for machine-to-machine communication when
SQL*Net connections are not possible, for instance in cloud environments. The REST Administration Interface enables administrators to automatically fetch usage metrics for an Oracle Application Express instance with a REST client.
The REST Administration Interface requires Oracle REST Data Services (ORDS) release 3.0.5 or later.
