Create request Correlation-IDs via middleware and pass both this globally unique `Correlation-ID` and any user provided `Request-ID` to the global log context.

VersionLaravelPHP1.\*10.\* | 11.\* | 12.\*8.1.\* | 8.2.\* | 8.3.\* | 8.4.\*Motivation
----------

[](#motivation)

Each and every request should have a unique *Correlation ID* which uniquely determines the user interaction. This *Correlation ID* should then be added to all log entries as context, to error reporting and to any subsystem like external API calls or queued jobs. Doing so, makes is possible to track relevant touch points for a given user request. Read more [here](https://microsoft.github.io/code-with-engineering-playbook/observability/correlation-id/).

A client can also provide a *Request ID* which it is good practice to return again in the response and correlate to the *Correlation ID*. Read more [here](https://http.dev/x-request-id).

Installation
------------

[](#installation)

You can install the package via composer:

```
composer require bilfeldt/laravel-correlation-id
```

### Assigning Correlation ID to requests

[](#assigning-correlation-id-to-requests)

Note

Ideally, the unique Correlation ID should be created at the **very first touch point** of your infrastructure like the initial server which could be a load balancer.

As it can be tricky to create *Correlation ID* on the server level (I do accept a PR with suggestions on how to do this in Nginx 😃) and this is so easy in Laravel using middleware. This package provides a middleware for creating a *Correlation ID* and attaching it to the request as a header `Correlation-ID` and to the response header as well. You should assign the correlation id using a global middleware pushed as the first middleware to be applied.

#### Laravel 11

[](#laravel-11)

Registering a global middleware in Laravel 11 is done in the `bootstrap/app.php` file:

```
// bootstrap/app.php

use App\Http\Middleware\EnsureTokenIsValid;
use Bilfeldt\CorrelationId\Middleware\CorrelationIdMiddleware

->withMiddleware(function (Middleware $middleware) {
     $middleware->prepend(CorrelationIdMiddleware::class);
})
```

#### Laravel 10 and below

[](#laravel-10-and-below)

In Laravel 10 and below then a global middleware is added in the `$middleware` property in `app/Http/Kernel.php`:

```
// app/Http/Kernel.php

/**
 * The application's global HTTP middleware stack.
 *
 * These middleware are run during every request to your application.
 *
 * @var array
 */
protected $middleware = [
    \Bilfeldt\CorrelationId\Middleware\CorrelationIdMiddleware::class, //
