Correlation Identifier¶

This page explains how you can implement a sample scenario of Correlation Identifier using WSO2 Micro Integrator.

Introduction to Correlation Identifier¶

The Correlation Identifier EIP facilitates a unique identifier that indicates which request message a given reply is for. It enables a requester who has received a reply to know which request the reply is for.

How WSO2 Micro Integrator implements the EIP¶

The message flow of the Micro Integrator automatically manages requests sent by a client by injecting a unique identification number into the message context of each request. When the response arrives, the message will be uniquely identified using this number, allowing the requester to distinguish between requests.
