    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.
