How to offer PDF against leads

Hi,

On each article I would like to have a lead magnet and when readers subscribe to it, they’re automaticaly redirected to the pdf version of the article.

For this I’m using the plugin Thrive Leads and after subscription I configure it to reveal the PDF button with the shortcode “[bws_pdfprint display=’pdf’]”, but the button doesn’t appear, I have a blank.

I also tried to redirect directly readers after subscription to a template url like “https://mywebsite/%postname%/?print=pdf, but it doesn’t work, the redirection doesn’t understand the “%postname% tag in the url and I have a 404 error page.

The only solution I’ve found is to create one lead magnet for each article and redirect manually to the goood url. Example : if a visitor read mywebsite.com/article and want the PDF version, I redirect him to mywebsite.com/article//?print=pdf after subscription to the lead magnet.

This solution work, but I have 150 articles, so that’s a lot of work to create manually 150 leads magnets…

Is it possible to automate it ? I’ve found some websites who seems to use this technique with PDF & Print.

Thank you
