You may generate PDFs in Laravel Cloud by leveraging Cloudflare’s Browser Rendering API. To get started, generate a Cloudflare API token that has the Account.Browser Rendering permission and locate your Account ID from your Cloudflare dashboard URL.

​
Using Laravel PDF

Spatie’s Laravel PDF package provides a convenient wrapper around Cloudflare’s Browser Rendering API via its built-in Cloudflare driver. No Node.js or Chrome binary is required on your instances. First, install the package via Composer: 
composer require spatie/laravel-pdf
Then, add the following environment variables to your Cloud environment’s environment variable settings: 
LARAVEL_PDF_DRIVER=cloudflare
CLOUDFLARE_API_TOKEN=your-api-token
CLOUDFLARE_ACCOUNT_ID=your-account-id
Once configured, you may generate PDFs using the Pdf facade. For example, the following controller method renders a view as a PDF and streams it as a download to the browser: 
use Spatie\LaravelPdf\Facades\Pdf;

public function download()
{
    return Pdf::view('pdfs.invoice', ['invoice' => $invoice])
        ->format('a4')
        ->download('invoice.pdf');
}
For more information on available options such as custom paper sizes, margins, headers, and footers, please refer to the Laravel PDF documentation.

​
Manual Usage

If you prefer to call the Cloudflare API directly without an additional dependency, add a cloudflare entry to your services.php config file: 
'cloudflare' => [
    'api_token' => env('CLOUDFLARE_API_TOKEN'),
    'account_id' => env('CLOUDFLARE_ACCOUNT_ID'),
],
Next, set these environment variables in your Cloud environment’s environment variable settings. Now you may call the Cloudflare PDF API using Laravel’s built-in Http facade. The following example demonstrates how to generate HTML from a view and stream the response as a downloadable PDF to the browser from a controller method: 
use Illuminate\Support\Facades\Http;

public function download()
{
    return response()->streamDownload(function () {
        $token = config('services.cloudflare.api_token');
        $accountId = config('services.cloudflare.account_id');

        echo Http::withToken($token)
            ->post('https://api.cloudflare.com/client/v4/accounts/'.$accountId.'/browser-rendering/pdf', [
                'html' => view('view-to-render')->render(),
            ])
            ->body();
    }, 'file.pdf', [
        'Content-Type' => 'application/pdf',
    ]);
}
