At work, my job relies partly on a third-party vendor for PDF conversion. This is possible on the SharePoint on-premise version of Nintex but on O365 it's a completely different problem. We haven't been able to do this at all.
Since we're not able to rely on this tech for converting to PDF in Nintex for O365, it makes it difficult for the clients we work with who want PDF copies of form submissions. It's just better to stick to Nintex for SharePoint on-premises. However, I'm hoping to find a solution that I can use here.
I did some digging to determine how the list item's form is rendered. When you go to the list item URL, the resulting form is embedded in an iframe and looks to be injected with JavaScript. I don't understand the full process though.
The third party I use has a REST API where I can pass in HTML to be converted. I would like to know if there is a URL I can use to get the form HTML that I can then use to convert to a target format?
