Digital download with paypal

by EricShaun
8 replies
Wanting to sell a digital download on my site with paypal which redirects the user to a download page afterwards.

I need a way to stop piracy though, so maybe the link is only displayed if it redirects from the paypal cart or something. Or so the download page logs the IP and creates a code that you activate in the program.

Ideas?

    Ejunkie is good, simplifies the whole process, they supply the payment processing cart that links to your paypal, download page and thank you page (or you can use your own), protection, and the buy buttons, as well as access to run affiliates in house. All you do is upload your files, set your price etc to your account, and copy and paste the payment buttoncode into your site..
    It's free to try for severn days I think, then $5 a month for up to 10 products...

    Think that is what your looking for!

    Did you know that when you upload a pdf to your website that it gets indexed by Google.

    When you enter this in google,

    Filetype : pdf for say "forex trading", you get a every single pdf that has been indexed as a PDF including the download page many paid products.

    There are two ways to stop PFD theft you can create a robot.txt file in your directory. When a robot crawls your site it looks for the robots.txt file, because that is a set of instructions to the robot. If it doesn't find one it assumes automatically that it may crawl and index the entire site.

    You can create a simple robots text file and instruct it to crawl all areas of your website. This is done by opening your editor and creating a page called robot.txt, the code below allows robots to crawl all files, because there is no instruction after the disallow

    User-agent: *
    Disallow:

    To create a robot text file that does disallow the robots and stops something getting indexed then you need the following

    PHP Code:
    User-agent: *
    Disallow: /filename.pdf


    All the instructions can be placed on one file, it is not necessary to create multiple ROBOT TXT FILES. This stops robots from indexing your PDF's, but you can create other instructions such as banning images or stats.
    User-agent: *
    Disallow: /images/
    Disallow: /stats/
    Disallow: /filename.pdf

      The robots.txt file can prevent crawling, but it doesn't prevent indexing. Crawling and indexing are two different things. If you don't want a page indexed, then you have to put the appropriate meta tag in the <head> section of the page. Obviously, you can't do that with PDFs and other types of files. You can, however, place these files in a directory that is not publicly accessible. In order for an authorized visitor to download said files, the web application would need to incorporate some functionality that retrieves the files in such a way that their true locations are not revealed.

      Another word about the robots.txt -- if you put the sensitive file names in there, that's not going to stop thieves from figuring out the full paths to the files and downloading them directly. You've just it made it that much easier for them by listing the files in the robots.txt.

      This is why it's best to use a third-party solution for product delivery such as e-junkie because they handle such security issues. The way that spoofing and other fraud attempts are foiled is by using an encrypted PayPal payment button in conjunction with code that checks to see if the Instant Payment Notification (IPN) message sent to your website was actually sent by PayPal. This is handled by e-junkie and other product delivery services. You can, of course, do it all on your own, but that requires extensive technical knowledge of the PayPal APIs (application programming interfaces).

    I use eJunkie and encourage others to do so as well. It's a great system and easy to use. With them you can also limit the timeframe a link is valid for.

    Even then all someone needs to do is download once, request refund and then upload files to mediafire. You'll need a protected PDF to curb that.

    You're going to fail. If you're afraid of failure then you do not belong in the Internet Marketing Business. Period.

      Eric,

      Pringrod and BloggingPro have got your back. Do a search for e-junkie on this forum, titles only, and you will get a good, free education.

      You can even add AWeber if you want.

      All the best.

    The referrer can be spoofed so watching for referrals from the PayPal cart wouldn't work. It may be worth using something that captures the IP and generates a unique code based on it. But that would require the digital download to contact the server to verify code - which also can be reverse-engineered.
    May be worth generating unique page per download, good only once, then disappears. Depends on what back end coding you use...

      You can use the Paypal API and write your own small script if you have programming knowledge and want to save the money.

      Here is how you do it:

      Each payment has a unique ID,
      Check if that payment was completed,
      Generate a link that is "secure" which means it will allow to download the file (php readfile()) and that allows download only x times or for x hours

      Sadly there is no airtight security. Even Passwords can be shared or the file simply gets passed around so don't spend too much time on this.

    Dl guard is pretty cool to use. I hide the file before the public_html directory and refer back to it with DLG. No one is going to happen upon it. Good support on their forums.

    I have no agenda but to help those in the same situation. This I feel will pay the bills.
