With the batch API you can easily convert a whole set of web pages into a single PDF or into individual PDFs. This allows you to convert your entire website into PDF or to take different webpages from different sources and convert them into one PDF. You can use it to create customized PDF backups of your complete site or to create high-quality reports, e-books, brochures and much more!
We also offer a manual way of doing all this in our members area. Read more about that here!
Our batch Web to PDF API takes a license and either a set of URLs or a sitemap as input and then schedules a job on one of our servers. As soon as the job is finished you will be notified by email. You can also use other options to monitor the progress yourself of course.
All you need to do is just send a request similar to this, which converts the pages of http://www.example.com (indicated by its sitemap) to one large PDF:
Each request should at least have the following components:
Additionally the following parameter decides whether we will create a single PDF for all your conversions or individual PDFs:
NB: Each URL in the batch counts as one conversion and by default we allow a maximum of 500 conversions per batch. Please contact us if you need more conversions per batch.
You can set all options that we support for the regular HTML to PDF API for the batch API. This includes options for page layout, headers and footers, but also encryption settings, watermarking options and custom backgrounds. You can set these options as default for all the conversions in the batch and then override them for each conversion in the batch.
Example: If you want to set the default orientation of the conversions to A4 format and portrait orientation, you would use the following request.
The table below some examples of the settings that you can change to control the conversions. For a full overview of options please refer to the documentation of the HTML to PDF API.
|page_size||Page size, such as A4, Letter etc. See the full list for details.|
|orientation||Portrait or Landscape orientation|
|content||Controls which content of the page you want to convert or exclude. See part of page conversion for more info.|
|css_media_type||Use print for the print friendly layout (CSS media type 'print') if your web page has one|
|header||HTML that you want to use as header|
|footer||HTML that you want to use as footer|
The header and footer can be specified in HTML and we also support extra parameters for dates and page numbers. Have a look at the extensive documentation.
The options that you have used above are defaults that will be taken for all conversions in the batch. In a lot of cases you may want to have different options for different web pages within the batch and then you can override these options on a case by case basis.
You might want to have all pages in your final PDF in landscape, but the page(s) of the first conversion in portrait. Using the 'exceptions' parameter will allow you to do so.
|exceptions[orientation]=portrait||Sets the orientation of the 1st PDF in the batch to portrait.|
|exceptions[page_size]=A3||Sets the page size of the 2nd PDF in the batch to A3|
|exceptions[width]=210||Sets the width of the 12th PDF to 210mm (mm is default if nothing is specified).|
This will create this 12th PDF as a single long one page PDF.
Our batch API returns HTTP response codes, which you can check to see if the conversion was successful or not. The following is the list of return codes we use.
|200 OK||Your conversion was processed succesfully|
|400 Bad Request||You didn't specify anything to convert or your data was malformed|
|401 Authorization required||You specified an invalid license key|
|429 Too Many Requests||You have overrun a usage limit for your plan|
|503 Service unavailable||You are sending multiple requests at the same time to the API from the same IP address|
We also return output on the job details. By default we return these in JSON format and you can use the output parameter to get it in different format (json = JSON, text = text, html = html or none = no output).
Typically you'll get something like this as a result in case of a successful job creation:
array ( 'job' => 5110, 'priority' => '1', 'merge' => true, 'conversions' => 16, 'urls' => array ( 1 => 'http://www.example.com/', 2 => 'http://www.example.com/developer', 3 => 'http://www.example.com/payment-methods-and-security', 4 => 'http://www.example.com/customer-service', 5 => 'http://www.example.com/customization', 6 => 'http://www.example.com/features-overview', 7 => 'http://www.example.com/contact-us', 8 => 'http://www.example.com/localization-global-payments', 9 => 'http://www.example.com/clients', 10 => 'http://www.example.com/subscription', 11 => 'http://www.example.com/in-app-purchases', 12 => 'http://www.example.com/purchases', 13 => 'http://www.example.com/payments', 14 => 'http://www.example.com/relationship-rights-management', 15 => 'http://www.example.com/faq', 16 => 'http://www.example.com/optimization', ), )
You can get one or more notifications when your job completes at our server or you can track the progress yourself with the batch monitor API (see below). If you just want to get notified upon completion, then you use the following parameters in the API call:
If you added a callback URL to the API call then we will POST the following data to the callback URL upon completion of the job. You will be able to use these to download the results.

You can also track the status and progress of your batch jobs via a separate HTTP request. This request by default will give you a JSON response indicating job details and status.
Just send a request similar to:
The request can have the following components:
The output that you will receive will look something like this. Please be aware that we may add fields to the structure in the future!
array ( 219 => array ( 'submitted' => '2015-05-07 18:10:17', 'finished' => '2015-05-07 19:54:00', 'status' => 'completed', 'success' => true, 'conversions' => '27', 'pages' => '27', 'download' => 'https://pdfmyurl.com/download?id=51223c91336af3', ), 220 => array ( 'submitted' => '2015-05-07 18:44:50', 'status' => 'processing', 'conversions' => '33 out of 48', ), 221 => array ( 'submitted' => '2015-05-07 18:45:59', 'status' => 'waiting', 'conversions' => '0 out of 27', ), )
Note that the 'status' field will indicate if your job is 'waiting' / 'processing' or 'completed' and the 'success' field will indicate true when everything went well or false when something went wrong.
We kindly request that you do NOT send non-stop requests to the monitoring API. The data is only updated once per second and we therefore ask you to only send a request every few seconds or so.
