Save your PDF online and get back a URL in PHP with Guzzle

In this guide, we'll show you how you can generate a PDF document from HTML and get back an URL instead of the raw PDF. This allows you to share the link directly to your users or redirect them to that page.

To do so, we are going to pass the filename parameter to the request. It expects a string that will be the name of the file once it is saved on our servers.

use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;

# You can get an API key at
$api_key = 'sk_xxxxxxxxxxxx'

$params = array (
    'source' => '',
    'filename' => 'example.pdf'

// Create a Guzzle client
$client = new Client();
try {
    // Make the POST request
    $response = $client->post('', [
        'headers' => [
            'Content-Type' => 'application/json',
            'Authorization' => 'Basic ' . base64_encode('api:' . $api_key)
        'json' => $params

    echo 'The PDF document was generated and is available online via the url in the response';
} catch (RequestException $e) {
    if ($e->hasResponse()) {
        $statusCode = $e->getResponse()->getStatusCode();
        $reasonPhrase = $e->getResponse()->getReasonPhrase();
        throw new Exception("Request failed with status code $statusCode: $reasonPhrase");
    } else {
        throw new Exception("Request failed: " . $e->getMessage());

In the above example, we used the filename parameter to specify the name of the file once it is saved on our servers. The response will convert the document but return a JSON response instead of the raw PDF.

The body of the response will be similar to this:

    "success": true,
    "url": "",
    "filesize": 34980,
    "duration": 1237,
    "response": {
        "status-code": 200,
        "content-length": 0,
        "requests": 0,
        "duration": 1085.6739225387573
    "executed": "2024-03-06T10:05:51.516413",
    "pdf_pages": 1

NOTE: Using the filename does save your document on our S3 storage for 2 days. After two days, the document is automatically deleted.

NOTE: Since we store your documents on our server, this command is not recommended if you want to be HIPAA compliant.

For further details on the filename property and its usage, please refer to our dedicated documentation.
