1-Click Upsells, Downsells and OTO’s are now extremely simple to implement using the new “Upsell Tree” plugin for DAP.

And this plugin works with Paypal Website Payments Pro!

What you need before you can use this plugin

1. You need a Paypal Website Payments Pro merchant account with Recurring Billing enabled.
2. You must have SSL (secure server) enabled on your web site. Ask your web host to enable SSL for your site.
3. You must have a working version of DAP 3.6+.

Installation & Setup of UpsellTree

1. You need at least DAP v3.6 for this. So login to your DAP account and download the latest version of DAP and the LiveLinks.
2. Follow standard procedure for installing DAP (OR) upgrading your DAP & LiveLinks versions. Nothing different there.
3. Purchase the UpsellTree plugin, login to your DAP account and download the plugin zip file, PaypalUpsellTree.zip .
4. Unzip PaypalUpsellTree.zip to your desktop. It will unzip the files to a new folder on your desktop, called “PaypalUpsellTree”.
5. Upload all the files inside, directly to your “dap” folder on your web site. DO NOT upload the folder itself.
6. Log in to your Paypal account and retrieve the following 3 pieces of information:
   * Paypal API Username
   * Paypal API Password
   * Paypal API Signature
7. Now log in to your DAP Dashboard and go to “Config > Payment Processing“.
8. Enter the Paypal API Username, Paypal API Password, and Paypal API Signature that you noted down earlier (Step #9 above) into the respective fields, and click  “Update” next to the fields to save the changes.
9. This step applies to you only if you are already using 1ShoppingCart with DAP (if not, skip to next step):
   Be sure to disable the “Email Order” cron job from your web hosting control panel (“Cron Jobs” screen), because you don’t want your orders to be double-processed.
10. Go to the “Products” page. You will now see a few new fields (some because of of DAP 3.5, some because of the new plugin).
    
    A) Product Price: For a 1-time purchase product, this is the product’s purchase price. For a recurring product, this is the “recurring” price (what the customer gets charged month after month).
    B) Trial Amount: This is only if there’s a trial amount. If no trial, leave this empty.
    C) Recurring Count: How long is your subscription? If you said “Forever”, then enter the number 9999 here. If it ends after 6 months, then enter 6 here.
11. Set these fields to valid values.
12. NOTE: The DAP Authorize.net allows 1 trial. So in the recurring cycle fields, make sure “Payment/Trial Period #2″ and “Payment/Trial Period #3″ are both the same (set to same number of days: like 30). Example below shows the setting for a “7 day” trial period, followed by recurring payments every “30 days”.
    
13. If you are not offering a trial, then just set the Trial Amount to $0.00. But if you really wanted to offer a FREE TRIAL, then you must set the Trial Amount to at least $0.01 (1 penny).
14. Once you’ve saved the product, you can now click on any of the two new “Generate… Button Code” links that are located right below the product list combo box. Image below shows the Authnet links. Similar buttons will show up for Paypal too.
    
15. “Generate Paypal Buy Button” link:
    This generates the buy button HTML code for your product, which you can then directly paste into your sales page. When you click on this link, you will get a pop-up that shows the actual HTML code for your button. The price, trial price, and recurring options are all taken from your Product settings. So make sure you have saved your Product changes before you click on this link.
    
16. Here’s what the HTML code looks like:
    <form name="generate_paypal" method="post" action="https://www.contentresponder.com/dap/buy.php">
<input type="hidden" name="item_name" value="Example Subscription Product"/>
<input type="hidden" name="description" value="This is a dummy Subscription Product with a monthly subscription - payments every 30 days." />
<input type="hidden" name="amount" value="1.00" />
<input type="hidden" name="trial_amount" value="0.01" />
<input type="hidden" name="total_occurrences" value="9999" />
<input type="hidden" name="is_recurring" value="Y" />
<input type="hidden" name="recurring_cycle_1" value="30" />
<input type="hidden" name="recurring_cycle_2" value="30" />
<input type="hidden" name="recurring_cycle_3" value="30" />
<input type="hidden" name="payment_succ_page" value="https://www.contentresponder.com/dap/continue.php?url=/dap/upsell1.html" />
<input type="hidden" name="payment_gateway" value="authnet" />
<input type="hidden" name="is_submitted" value="Y" />
<input type="submit" value="Buy Now" />
</form>
17. If you’re doing upsells, the only thing you need to do is, look for the “payment_succ_page” field in the above form. By default it is pointing to:
    https://www.contentresponder.com/dap/continue.php?url=/dap/upsell1.html
18. Modify the “upsell1.html” file within your dap folder, to make your 1-Click Upsell offer. Or if you don’t wish to use 1-Click upsells, you can make just about any kind of upsell offer on that page. The upsell1.html that comes with the plugin has a sample upsell page already created for you, just so you get an idea of what that will look like.
19. On the upsell page, if you want to upsell say, Product B, then make sure you set up “Product B” ahead of time in DAP, and set up the price and recurring options. Then for upsell products only, click on the “Generate Authnet 1-Click Upsell” link to generate the 1-Click Upsell Buy button code, as the upsell buy button is slightly different than the ‘regular’ buy button code. Now take the upsell buy button code like you did before, and paste it in upsell1.html. That’s it.
20. You can repeat this process for unlimited upsells, downsells and one-time offers. No limits.

That’s it.

While it looks like a LOT of steps, that is only because we have to explain the steps in detail so they are clear. In reality, it is very simple to set up, and starting from scratch, if you have DAP & SSL already installed, it shouldn’t take you more than 1/2 hour to set up your 1-Click Upsells/Downsells/OTO’s. And if you’re not using Upsells/Downsells, then it can be done even faster.
