• 1SiteAutomation.com (a 1Shoppingcart.com private label)
• Paypal Standard
• Paypal Website Payments Pro
• e-Junkie (e-J does not allow recurring payments)
• Authorize.net
• WorldPay
• ClickBank

And because DAP integrates with 1ShoppingCart, in turn, it essentially integrates with all payment providers support by 1ShoppingCart.

1-Click Upsells

If you use DAP as a shopping cart, then you can do 1-Click Upsells/Downsells like the pros. DAP allows you to do 1-Click Upsells using Authorize.net, Paypal Website Payments Pro and Paypal Standard.

Of course, if you need advanced shopping cart features – like ability to calculate shipping, tax, and coupons, then you’re better off using 1ShoppingCart.

1ShoppingCart & GoDaddy

If you want automated recurring order processing using 1ShoppingCart, then DAP needs to be able to process the recurring email notifications sent by 1ShoppingCart, which it does on the back-end when the DAP-Cron job runs every 10 minutes. However, if you’re using Godaddy as your web host (doesn’t matter if you’re using them as the domain name registrar), then because GoDaddy disables a key PHP library (“imap”) on all their servers for whatever reason, DAP is not able to do process the recurring order email notifications from 1ShoppingCart.

So if you’re using 1SC & GoDaddy hosting, you will have to end up doing manual cancellations if any member cancels their subscription, or if their credit card fails and their recurring payments don’t get processed.

But 1ShoppingCart order processing works great with all other hosts.

This OTO script can also be used for making Upsells and Downsells too!

Only thing you have to remember is, that these won’t be 1-Click Upsells or 1-Click Downsells.  If you want true 1-Click Upsells, then do check out our plugin, Upsell-Tree, which allows you to do exactly that.

The Basics

1. There is a file in your dap folder, called continue.php . This is the OTO script.
   
2. Create and upload as many upsell and downsell pages – named, say, upsell1.html, downsell1.html, upsell2.html, downsell2.html – etc and store them in your root folder – the folder where your home page is (not in the dap folder).

Setting up continue.php

When you set up your buy button, after the sale, configure the “return url” to be:

http://YourSite.com/dap/continue.php?url=/upsell1.html

Of course, you should have already created a page called upsell1.html and uploaded it to the root of your web site (where your home page is).

So after your buyer has purchased your product, and arrive at this first upsell page, the URL they see in their browser will actually look like…

http://YourSite.com/dap/continue.php

They will not see the text “/upsell1.html” in the url, because continue.php would have already stripped out the file name from the end of the link.

So even if they bookmark it or share it with others, the URL they see will just be http://YourSite.com/dap/continue.php – which means they can’t get back to that page, and neither will the people they have shared the link with.

On each upsell page, you can make any offer you want. Let’s say you put the buy button on this upsell page to buy a different product. Now when you create the buy button for this new upsell product, make sure the “return url” for that button, is now…

http://YourSite.com/dap/continue.php?url=/upsell2.html

And you can also put a “No Thanks” button on each of these upsell pages, which could in turn take them either to a downsell page, or to an order completion page (where you thank them for your purchase).

Button Code For “No Thanks”

If your “No Thanks” button is going to lead to a downsell page, then here’s the code:

<form action=“http://YourSite.com/dap/continue.php?url=/downsell1.html” method=”post” >
<input type=”submit” value=”No, Thanks. I’ll skip this special offer” />
</form>

If your “No Thanks” button is going to lead to a final thank you page, where there are no more upsells or downsells, and where you simply thank your buyer for the purchase, then the code for that is:

<form action=“http://YourSite.com/dap/continue.php?url=/thankyou.html” method=”post” >
<input type=”submit” value=”No, Thanks. I’ll skip this special offer” />
</form>

Yes, you do need to be just a little bit technical for this. So, if you absolutely did not understand anything written above, then you should probably not be attempting to be doing OTO’s.

But if you simply have questions about how to use this for what you’re thinking to do, please feel free to ask them in the comments below.
