Simple URL link to convert html page?

Is there a way to just create an url string that has all parameters for a pdf to be created?

I want to provide a link in an email that a user can click and it will automatically start downloading the pdf.

There are many other pdf services that can do this but they do not format the pdf correctly. Can this be done with pdf crowd?

How do I format the url?

I tried the following unsuccessfully:

http://pdfcrowd.com/api/pdf/convert/uri/?src=https://creatorexport.zoho.com/xxx/prod/print/Quote/&Request_ID=11215512&key=myapikey&username=myusername


Thanks
