  title: Citrix NetScaler NITRO REST Authentication System API
  description: The NITRO (NetScaler Interface Through RESTful Operations) API provides programmatic access to configure, monitor, and manage Citrix NetScaler (ADC) appliances. Built on REST architecture using HTTP/HTTPS, the API supports comprehensive management of application delivery controller features including load balancing virtual servers, content switching virtual servers, system configuration, and appliance-level settings. All NITRO operations are logged to /var/nitro.log on the appliance.
