The function config was not found. Maybe you did not declare it correctly or list all dependencies?

        if (empty($secret)) {
            throw WebhookFailed::noSecretKeyProvided();
        }

        try {
            Webhook::parse($payload, $signature, $secret);

            return false;
        }

        return true;
    }
