@ioannis-papikas Thank you for the merge request; we appreciate your effort! 👍

My colleague @johankrijt did most of the work on this package, so he's probably the one that can help you out the best.

A comment from my side: I would like this upgrade to be as smooth as possible for current users (including a lot of our own website/applications), so I already would like to give some suggestions to achieve that by handling the missing .env entry and falling back to the default without suppressing any errors. Would you mind taking a look at those comments?

To prevent a breaking change, we could move the endpoint parameter to be the third parameter and assign the self::URL in the constructor.

Suggested change

	public function __construct(
	private readonly string $sourceToken,
	private readonly string $endpoint,
	private CurlHandle|false $handle = false,
	) {
	}
	public function __construct(
	private readonly string $sourceToken,
	private CurlHandle|false $handle = false,
	private readonly string $endpoint = self::URL,
	) {
	}

With my constructor suggestion, you can change this to:

Suggested change

	$url = @$this->endpoint ?: self::URL;
	curl_setopt($this->handle, CURLOPT_URL, $url);
	curl_setopt($this->handle, CURLOPT_URL, $endpoint);

Suggested change

	public function __construct(string $sourceToken, string $endpoint, ?string $appName = null, int|string|Level $level = Level::Debug)
	public function __construct(string $sourceToken, ?string $endpoint = null, ?string $appName = null, int|string|Level $level = Level::Debug)

As the endpoint might not be set by every user of this package, it should be nullable and null by default, I think.

Suggested change

	string $endpoint,
	?string $endpoint = null,
