cloudconvert-php

This is the official PHP SDK for the CloudConvert API v2.

Install

To install the PHP SDK you will need to be using Composer in your project.

Install the SDK alongside Guzzle:

composer require cloudconvert/cloudconvert-php guzzlehttp/guzzle

This package is not tied to any specific HTTP client by using PSR-7, PSR-17, PSR-18, and HTTPlug. Therefore, you will also need to install packages that provide psr/http-client-implementation and psr/http-factory-implementation (for example Guzzle).

Creating Jobs

use \CloudConvert\CloudConvert;
use \CloudConvert\Models\Job;
use \CloudConvert\Models\Task;


$cloudconvert = new CloudConvert([
    'api_key' => 'API_KEY',
    'sandbox' => false
]);


$job = (new Job())
    ->setTag('myjob-1')
    ->addTask(
        (new Task('import/url', 'import-my-file'))
            ->set('url','https://my-url')
    )
    ->addTask(
        (new Task('convert', 'convert-my-file'))
            ->set('input', 'import-my-file')
            ->set('output_format', 'pdf')
            ->set('some_other_option', 'value')
    )
    ->addTask(
        (new Task('export/url', 'export-my-file'))
            ->set('input', 'convert-my-file')
    );

$cloudconvert->jobs()->create($job)

You can use the CloudConvert Job Builder to see the available options for the various task types.

Uploading Files

Uploads to CloudConvert are done via import/upload tasks (see the docs). This SDK offers a convenient upload method:

use \CloudConvert\Models\Job;
use \CloudConvert\Models\Task;


$job = (new Job())
    ->addTask(new Task('import/upload','upload-my-file'))
    ->addTask(
        (new Task('convert', 'convert-my-file'))
            ->set('input', 'upload-my-file')
            ->set('output_format', 'pdf')
    )
    ->addTask(
        (new Task('export/url', 'export-my-file'))
            ->set('input', 'convert-my-file')
    );

$job = $cloudconvert->jobs()->create($job);

$uploadTask = $job->getTasks()->whereName('upload-my-file')[0];

$cloudconvert->tasks()->upload($uploadTask, fopen('./file.pdf', 'r'), 'file.pdf');

The upload() method accepts a string, PHP resource or PSR-7 StreamInterface as second parameter.

You can also directly allow clients to upload files to CloudConvert:

<form action="<?=$uploadTask->getResult()->form->url?>"
      method="POST"
      enctype="multipart/form-data">
    <? foreach ((array)$uploadTask->getResult()->form->parameters as $parameter => $value) { ?>
        <input type="hidden" name="<?=$parameter?>" value="<?=$value?>">
    <? } ?>
    <input type="file" name="file">
    <input type="submit">
</form>

Downloading Files

CloudConvert can generate public URLs for using export/url tasks. You can use the PHP SDK to download the output files when the Job is finished.

$cloudconvert->jobs()->wait($job); // Wait for job completion

foreach ($job->getExportUrls() as $file) {

    $source = $cloudconvert->getHttpTransport()->download($file->url)->detach();
    $dest = fopen('output/' . $file->filename, 'w');
    
    stream_copy_to_stream($source, $dest);

}

The download() method returns a PSR-7 StreamInterface, which can be used as a PHP resource using detach().

Webhooks

Webhooks can be created on the CloudConvert Dashboard and you can also find the required signing secret there.

$cloudconvert = new CloudConvert([
    'api_key' => 'API_KEY',
    'sandbox' => false
]);

$signingSecret = '...'; // You can find it in your webhook settings

$payload = @file_get_contents('php://input');
$signature = $_SERVER['HTTP_CLOUDCONVERT_SIGNATURE'];

try {
    $webhookEvent = $cloudconvert->webhookHandler()->constructEvent($payload, $signature, $signingSecret);
} catch(\CloudConvert\Exceptions\UnexpectedDataException $e) {
    // Invalid payload
    http_response_code(400);
    exit();
} catch(\CloudConvert\Exceptions\SignatureVerificationException $e) {
    // Invalid signature
    http_response_code(400);
    exit();
}

$job = $webhookEvent->getJob();

$job->getTag(); // can be used to store an ID

$exportTask = $job->getTasks()
            ->whereStatus(Task::STATUS_FINISHED) // get the task with 'finished' status ...
            ->whereName('export-it')[0];        // ... and with the name 'export-it'
// ...

Alternatively, you can construct a WebhookEvent using a PSR-7 RequestInterface:

$webhookEvent = $cloudconvert->webhookHandler()->constructEventFromRequest($request, $signingSecret);

Signed URLs

Signed URLs allow converting files on demand only using URL query parameters. The PHP SDK allows to generate such URLs. Therefore, you need to obtain a signed URL base and a signing secret on the CloudConvert Dashboard.

$cloudconvert = new CloudConvert([
    'api_key' => 'API_KEY',
    'sandbox' => false
]);

$job = (new Job())
    ->addTask(
        (new Task('import/url', 'import-my-file'))
            ->set('url', 'https://my.url/file.docx')
    )
    ->addTask(
        (new Task('convert', 'convert-my-file'))
            ->set('input', 'import-my-file')
            ->set('output_format', 'pdf')
    )
    ->addTask(
        (new Task('export/url', 'export-my-file'))
            ->set('input', 'convert-my-file')
    );

$signedUrlBase = 'SIGNED_URL_BASE';
$signingSecret = 'SIGNED_URL_SIGNING_SECRET';
$url = $cloudConvert->signedUrlBuilder()->createFromJob($signedUrlBase, $signingSecret, $job, 'CACHE_KEY');

Setting a Region

By default, the region in your account settings is used. Alternatively, you can set a fixed region:

// Pass the region to the constructor
$cloudconvert = new CloudConvert([
    'api_key' => 'API_KEY',
    'sandbox' => false,
    'region'  => 'us-east'
]);

Unit Tests

vendor/bin/phpunit --testsuite unit

Integration Tests

vendor/bin/phpunit --testsuite integration

By default, this runs the integration tests against the Sandbox API with an official CloudConvert account. If you would like to use your own account, you can set your API key using the CLOUDCONVERT_API_KEY enviroment variable. In this case you need to whitelist the following MD5 hashes for Sandbox API (using the CloudConvert dashboard).
