It's very difficult to track a request across the system when we are working with microservices. We came out with a solution for that. We generate a unique version 4 uuid for every request and every service passes this id via request headers to other services. We call this correlation ID.



  • Install via composer
composer require proemergotech/correlate-php-laravel

Setup for Laravel 5

Add the ProEmergotech\Correlate\Laravel\LaravelCorrelateMiddleware middleware to the $middleware property of your app/Http/Kernel.php class.

Setup for Lumen 5

Add service provider to bootstrap/app.php in your Lumen project.

// bootstrap/app.php



This middleware automatically adds correlation id (coming from request header) to every log message. There are some macros added to the request object if you want to work with correlation id.

Using macros via request object:

if ($request->hasCorrelationId()) {
  $cid = $request->getCorrelationId();
// or if you can change the ID
