Study Notes

Experience API Implementation Details

  • Correlation ID is generated for each HTTP request.
  • Correlation ID is passed to the web store backend in the HTTP response.
  • Subsequent API invocations to the Experience API include the correlation ID.
  • The Experience API propagates the correlation ID to the Process API in a request header.
  • The Java EE application server (for the web store backend) automatically uses and transmits the thread-local correlation ID via standard HTTP headers.
  • No special code/configuration is needed in the web store backend, Experience API, or Process API for correlation ID management.

API Monitoring for Mule and Non-Mule Implementations

  • An organization wants to monitor Mule and non-Mule API implementations.
  • They want to check API availability and do not want external tools or extended IT footprint.
  • Anypoint Platform's Runtime Manager monitors availability of both Mule and non-Mule APIs.
