Once you set up your products in E-junkie Seller Admin, we provide you with ready-made HTML codes for your cart buttons. You would simply copy the codes from us and paste them into the HTML source of your own Web site pages, wherever you want our buttons to appear among your own layout, text and images.
Note the difference between View Cart vs. Add to Cart button codes. Each product has its own, unique Add to Cart button code, so paste that wherever in your site you want buyers to be able to add the corresponding item to their cart order. Your View Cart code is unique to you but the same for all of your products, so just make sure you paste one complete block of your View Cart code on every page that has any number of Add to Carts. The View Cart code manages the nice overlay-style cart that appears "inside" your page, and the View Cart button itself lets buyers view their cart order without having to add a new item to their cart.
A download link is appearing on the thank-you page we generate for you because you have enabled Single File Download in the product's settings, which you should only use if you provide us with a file to deliver to buyers. Normally, after the buyer finishes checkout and the payment processor confirms the buyer's payment was good and completed, we grant the buyer access to a unique thank-you page we generate for each transaction, where we automatically present the buyer's unique download link(s).
The download links we issue would expire after the number of attempts or hours (whichever comes first) that you specify in each product's settings, so even if a buyer shares their link with others, it soon becomes useless to everyone. We also send the buyer a thank-you email message for digital products, which automatically includes a link to reach the thank-you/download page in case they did not proceed to the download page after checkout.
If you would prefer to send buyers to a download page on your site, you would use the Redirection option in the product's settings, rather than using Single File Download if we aren't actually delivering the download for you. In this case, the link we provide on the thank-you page would access whatever Redirection URL you specify for the product, rather than starting a direct file download.
However, while we can expire these redirection links just like download links, buyers could still save the URL of the actual page on your site where they land after the redirection. The buyer could then share the URL of your site's download page and share the password you provide to access that page with others, who could simply visit that URL directly and enter the password to obtain a download without paying you first. This is why we recommend using our built-in download delivery feature, so we can issue each buyer their own, unique, expirable link to control such download theft.
Our system has no way of handling recurring payments such as a periodic subscription or installment plan. You may want to look into using PayPal's own Recurring Payments solution as-is or combined with a purpose-built membership management system such as FrontDeskApp, CheddarGetter, etc. You can use PayPal Recurring Payments at the same time as using E-junkie with PayPal, and they won't interfere with each other at all.
