Best practic to convert Eloqua Email ID (Deployment ID) to PDF file!

Summary:

When using the Eloqua Deployment API to send an email, I receive an Email ID in the response, which is perfect.

From there, I want to retrieve the email HTML content and convert it into a PDF file.

If I use the https://secure.p06.eloqua.com/API/rest/2.0/assets/email/deployment/{id} I will get:

"htmlContent":

"cssHeader":

"docType"

"htmlBody"

I want to take this code and convert it into a PDF.

I have searched extensively, but it is hard to find a good solution for Eloqua.

There must be a solid approach for doing this without relying on a lot of third-party components that only add complexity and increase the risk of errors.
