description: >-
  Citrix Cloud and Citrix DaaS REST APIs are governed by per-customer service throttles in the Citrix
  Cloud control plane. Specific per-second / per-minute thresholds are not published in self-serve
  form; clients should rely on HTTP 429 / Retry-After signaling and request increases via Citrix
  support. On-premises NetScaler / ADC NITRO and the Workspace API have their own throttling that is
  bounded by appliance / control-plane capacity.
notes: Verify exact thresholds inside the developer.cloud.com API reference and Citrix support
  channels. Numbers below are descriptive placeholders pending verification.
