PDF stamping activated correctly but not working

[lianel]

Hello,
I activated PDF stamping correctly, and inserted http://www.e-junkie.com/ecom/o_plug.php?ej_stamp_pdf=true&pdf_allow_copy=y&pdf_allow_print=y&pdf_pwd= several times now, but when I send myself a download link via send free download link, the PDF comes unstamped...
The Ebook is only 11MB, so it's not too big for stamping. Has this to do with the sending download link function, so that, if someone bought it, it would be stamped?
Or with the PDF Document itself: when I deactivate copy in the PDF document and save it, do I have to deactivate it in the product notification url as well,- could something like that affect the stamping?
Even if I allow copy and everything, save the PDF, upload it and use the original code without modification the PDF comes unstamped..
I'm thankful for any advice

Your Product Notification URL for PDF Stamping needs to start with https: rather than http:. Could you tell us where you found the http: version? We'd like to correct that.

Also note that if your original PDF is locked with a password (as would be required to disable document permissions such as printing), you would need to include that password after the &pdf_pwd= in your Product Notification URL for PDF Stamping.

Bear in mind Stamped copies cannot carry over any document restrictions from your original file anyway, but you can configure the URL to disable printing and/or copy-pasting, and we apply other reasonable document restrictions along with a randomized Master password to every Stamped copy, as this help page explains in more detail:

Sry, the https was correct in my Code, I mainly tried this Version (I don't use a Password):
https://www.e-junkie.com/ecom/o_plug.php?ej_stamp_pdf=true&pdf_allow_copy=n&pdf_allow_print=y
The original one:
https://www.e-junkie.com/ecom/o_plug.php?ej_stamp_pdf=true&pdf_allow_copy=y&pdf_allow_print=y&pdf_pwd=
and this one:
https://www.e-junkie.com/ecom/o_plug.php?ej_stamp_pdf=true&pdf_allow_copy=n&pdf_allow_print=y&pdf_pwd=
but none of them lead to stamped PDFs I send myself via send free download link, I have no other idea why it still won't work but that maybe the PDF is too large (11MB)??...
I uploaded different PDFs- without any disabled copy function as well..

This is where I have the wrong link from:

It appears the file you uploaded is locked with a password, so you must specify that password after the &pdf_pwd= at the end of your Product Notification URL -- e.g., if the document password were ABC123, then your URL would look like this:

https://www.e-junkie.com/ecom/o_plug.php?ej_stamp_pdf=true&pdf_allow_copy=y&pdf_allow_print=y&pdf_pwd=ABC123

BTW, this is our official help page for PDF Stamping; the information here is kept up-to-date and more comprehensive than that blog post you linked:

I uploaded a new PDF where I consciously chose the password added it into the code and it worked, thanks for the support!
