The Correlation Pattern, which depends on the use of Correlation ID is a well documented Enterprise Integration Pattern. - [The value of a correlation ID](https://blog.rapid7.com/2016/12/23/the-value-of-correlation-ids/) - [Identity Correlation on Wikipedia](https://en.wikipedia.org/wiki/Identity_correlation) Documentation ------------- [](#documentation) ### The Correlation ID Value Object [](#the-correlation-id-value-object) The correlation ID is a singleton class that will always return the same ID for the current life-cycle of the request. Calling `CorrelationID::toString()` will return a string and will return the same string for the whole live cycle of the application. You can compare a string to the Correlation ID by calling `CorrelationID::sameAs('your-string')`. By default it uses its internal implementation to generate a UUID v4 as value of the Correlation ID. If you are using [ramsey/uuid](https://github.com/ramsey/uuid), it will use it automatically. ### PSR 15 HTTP Middleware [](#psr-15-http-middleware) The middleware will automatically put the correlation ID into your request object as attribute and header value. By default both use the `CorrelationID` name. ``` $middleware = new CorrelationIDMiddleware( CorrelationID::toString() ); ``` ### Response [](#response) Since there is no standard for where this needs to be done, just add the correlation ID to your response where it suits your architecture or framework the best. ``` $response->withHeader('CorrelationID', CorrelationId::toString()); ``` For Symfony there is a [bundle](https://github.com/Phauthentic/correlation-id-symfony-bundle) available that will automatically make the Correlation ID available in the request and response object.
