Avoid the conversion on error when loading the document in PHP with Guzzle

In this guide, we'll show you how to abort the conversion when loading the distant source does not return a 2XX response.

When you're converting a document, you might want to avoid the conversion on error when loading the document. This can be done by setting the raise_for_status parameter to True in the request.

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

# You can get an API key at https://pdfshift.io
$api_key = 'sk_xxxxxxxxxxxx'

$params = array (
    'source' => 'https://www.httpstat.us/404',
    'raise_for_status' => true
)

// Create a Guzzle client
$client = new Client();
try {
    // Make the POST request
    $response = $client->post('https://api.pdfshift.io/v3/convert/pdf', [
        'headers' => [
            'Content-Type' => 'application/json',
            'Authorization' => 'Basic ' . base64_encode('api:' . $api_key)
        ],
        'json' => $params
    ]);

    // Get the response body
    $body = $response->getBody()->getContents();

    // Save the file to result.pdf
    file_put_contents('result.pdf', $body);

    echo 'The PDF document was generated and saved to result.pdf';
} 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());
    }
}

Passing raise_for_status to true will ensure that if PDFShift can not load your document, the conversion will fail with an error.

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