PDF Stamping is not working for me.
o Seller Admin > View/Edit/Delete Products -> select Send transaction data to a URL -> -> Enter the following URL in payment variable information URL: -> Submit
http://www.e-junkie.com/ecom/o_plug.php?e_stamp_pdf=true&
pdf_allow_copy=y&pdf_allow_print=y
Note: I don't have an editing/authoring password on the PDF file. So, I've removed the &pdf_pwd= as per the documentation.
I still don't see the stamping. Can someone help? Please take a look at the document that is on my account and let me know whether anything is wrong in the PDF file that I've uploaded.
Note: I created the PDF file using Adobe PDF creator directly from Microsoft Word.

Suppose we continue to give e-junkie a pdf file rather than a zip. Along with the name to zip the file into when the pdf stamping has been added.
As an ex-software developer, it seems that this would be far simpler, and take way less time that requiring e-junkie to unpack a pdf before adding the pdf stamping customization.
A zip would also provide a faster download, which might compensate, and perhaps even more than compensate for the extra time needed to zip the resultant pdf.
This would go a long way to satisfying the basic need, without needing a rewrite of the whole system for unusually complex non-standard requirements...

TysonAdditional stalling tactics to cover the extra delay required to unzip and rezip a collection of files (not to mention the additional time to stamp more than just one PDF) would only defer buyers' gratification even further, making for an unsatisfactory buyer experience.
...
Have you considered simply recompiling each of your PDF file collections into a single PDF for each bundle?
Yes I have considered this.. and this is what we'll be doing as a "fix" for now.
However... I don't really see how your logic makes sense.
The number of pages needed to "stamp" is identical regardless of whether we have two eBook files or one file. (If we take two 50 page ebooks and combine them into a single 100 page ebook.. isn't that the exact same amount of work for the stamping process? Does opening a PDF file really take *that* much additional processing?)
What you are saying as being the problem (slow stamping, delayed customer fulfillment, etc) doesn't make sense if you then turn around and suggest a possible "fix" is to simply add all the ebooks into one.
What am I missing?

Unzipping and (especially) rezipping files takes a lot longer than simply stamping a PDF file as-is. That's the additional, unacceptable delay I was referring to. At any rate, even if you'd find the added delay acceptable, we simply don't have any way to automate unzipping, stamping and rezipping, so we'd have to program that whole routine. We hadn't even thought of that when we wrote the Stamper in the first place, so at present it's only capable of stamping a single PDF file at a time. Development will put your request on the wishlist, but we can't promise it'd get done anytime soon considering everything else they're already working on.

Ok.. let's throw aside the unzipping issue for a bit. That's fine, and I understand the reasoning behind that.
However, what I don't understand is why you can't stamp a multi-file item. (ie: An item that includes multiple pdf files.
How is that any different then if we combine the two files into a single PDF?
There is no file to unzip/zip in that case.
No?

That is answered in my response to this suggestion:
CrisBCTSuppose we continue to give e-junkie a pdf file rather than a zip. Along with the name to zip the file into when the pdf stamping has been added...
The problem is the requirement to stamp a whole collection of separate PDF files that would be issued as a single product together, and we have no way for sellers to upload multiple files for a single product in the first place, other than compressing them into a single .zip that is simply issued to buyers as-is. The PDF Stamper currently won't even work with "package deal" bundles using the "Package files from other products" feature; it can only stamp a single PDF file that is uploaded for the exact product configured with the PDF Stamper URL.

This is software. Anything is possible. :)
I hope you'll consider this as a feature request. (The ability to stamp multiple PDFs selected in the "Package files from other products" feature.)
Thanks.

Hi, guys!
Just joined e-Junkie today and downloaded my ebook. I tried to get the pdf stamping to work, but it doesn't show. My situation is identical to Geek's on top of this page:
"PDF Stamping is not working for me.
o Seller Admin > View/Edit/Delete Products -> select Send transaction data to a URL -> -> Enter the following URL in payment variable information URL: -> Submit
http://www.e-junkie.com/ecom/o_plug.php?e_stamp_pdf=true& pdf_allow_copy=y&pdf_allow_print=y
Note: I don't have an editing/authoring password on the PDF file. So, I've removed the &pdf_pwd= as per the documentation.
"
My file is not zipped, I don't have a password and I also removed the &pdf_pwd= as adviced.
So what should I do??
Leena :)

Did you test this with a free checkout or the Send Free Link option? The Send Free Link option does not attach the PDF stamp. If you are using the free checkout, make sure you wait at least 15 minutes after setting up the PDF stamping before you test the free checkout.

Oh yes I did use the Send free link option! Never thought that would not attach the stamp. (Good point to remember in the future, thank you!) So I could be certain the stamp is there?
