You can get an API Key from PrexView

Set up your API Key

If you can setup enviroment variables

export PXV_API_KEY="YOUR_API_KEY"

Include the library

Composer installation
require __DIR__  . '/vendor/autoload.php';
Manual installation
require __DIR__  . '/vendor/prexview/src/PrexView.php';

Sending an XML

To send an XML string use $pxv->sendXML($xml, $options) method, this method will return a Response object on success or thrown an error.

Example
$pxv = new Prexview\Prexview();

$options =  new stdClass();

$options->template = 'supported_languages';
$options->output = 'pdf';

$xml = '<?xml version="1.0" encoding="UTF-8"?>
<languages>
  <lang code="en">English</lang>
  <lang code="es">Español</lang>
  <lang code="fr">Française</lang>
</languages>';

$file = 'test.pdf';

try {
  $res = $pxv->sendXML($xml, $options);

  file_put_contents($file, $res->file);

  echo 'File created: ' . $file;
} catch (Exception $e) {
  die($e->getMessage());
}

Sending a JSON

To send a JSON string or PHP standard object use $pxv->sendJSON($json, $options) method, this method will return a Response object on success or thrown an error.

Example
$pxv = new Prexview\Prexview();

$options =  new stdClass();

$options->template = 'supported_languages';
$options->output = 'pdf';

$json = new StdClass();

$en = new StdClass();
$es = new StdClass();
$fr = new StdClass();

$en->code = 'en';
$en->name = 'English';

$es->code = 'es';
$es->name = 'Español';

$fr->code = 'fr';
$fr->name = 'Française';

$json->languages = [$en, $es, $fr];

$file = 'test.pdf';

try {
  $res = $pxv->sendJSON($json, $options);

  file_put_contents($file, $res->file);

  echo 'File created: ' . $file;
} catch (Exception $e) {
  die($e->getMessage());
}
Response object
Property Type Description
id string Transaction ID.
file binary Document created by the service.
responseTime int Response time from service.
rateLimit int Maximum number of calls to the service.
rateLimitReset int Seconds to reset the rate limit.
rateRemaining int Number of remaining call to the service.
Options
Name Type Required Description
template string Yes Template's name to be used to document creation, you can use dynamic values.
output string Yes Type of document that will be created by PrexView service, it must be html, pdf, png or jpg.
note string No Custom information to be added to the document's metadata, it's limit up to 500 characters and you can use dynamic values.
format string No Type of data used to the document creation, it must be xml or json, this should be inferred from library methods.
templateBackup string No Template's name to use to be used if the option template is not available in the service.
Dynamic values

In template or note options you can use JSON sintax to access data and have dynamic values, for instance having the following JSON data:

{
  "Data": {
    "customer": "123"
  }
}

Your template or note can use any data attribute or text node, for instance:

'invoice-customer-{{Data.customer}}'

Then we will translate that to the following:

'invoice-customer-123'

And finally the service will try to find the template or note invoice-customer-123 in order to transform the data and generate the document.
