Hello,
You bought a wrong license type. In order to be able to use the HTML to PDF API <
https://pdfcrowd.com/api/html-to-pdf-api/>, you need to choose from the API plans here:
-- https://pdfcrowd.com/pricing/api/
Your current license does not grant API access. It allows generating customized PDFs using the online conversion form on our web site - <
https://pdfcrowd.com/#convert_by_url+with_options>.
If you don't need this functionality, just let us know and we will revert the $9.95 back to your Paypal account.
