About API Prioritization

For applications that call resources of various formats (like JSON or XML), API Prioritization lets you specify which calls are given priority and are sent to the origin during high-demand situations. Based on information in the inbound request, you configure the rules that determine which calls are prioritized.


The following diagrams show how API Prioritization works both during normal traffic flow and during times when your application is experiencing a large amount of traffic.

  4. Save your changes to the property.
