Starting DAP v4.2, we have consolidated both the Authorize.net & Paypal Payments Pro Upsell-Tree Plugins into one simple set of files, and it has been named the DAP Shopping Cart, which will allow you to both accept one time and recurring payments, as well as do 1-Click Upsells.

This consolidated set of files is named DAPShoppingCart.zip , and is available for download from the members’ area at http://DigitalAccessPass.com/dap/ .

Upgrading from DAP v4.2

If you are upgrading to DAP v4.2 from a previous DAP version, and you’ve been using Authorize.net or Paypal Payments Pro to accept payments, then you must also upgrade to the new DAP Shopping Cart.

So all you need to is…

1) Download the DAPShoppingCart.zip file from the members area

2) Unzip it to your desktop

3) Upload all files inside directly to your main “dap” folder on your site. (do not upload the folder named DAPShoppingCart – upload only the files inside this folder)

Warning: file_get_contents(/home/mysite/dap/upsell1.html) [function.file-get-contents]: failed to open stream: No such file or directory in /home/mysite/dap/continue.php(1) : eval()'d code on line 20


Solution: Create missing file.

Every buy button generated by DAP for Auth.net or Paypal Payments Pro, will look something like this…

<form name=”generate_authnet” method=”post” action=”https://www.DigitalAccessPass.com/dap/buy.php”>
<input type=”hidden” name=”item_name” value=”DAP Upsell Tree – Auth.net (T)”/>
<input type=”hidden” name=”description” value=”DAP Upsell Tree For Authorize.net” />
<input type=”hidden” name=”amount” value=”97.00″ />
<input type=”hidden” name=”trial_amount” value=”0.01″ />
<input type=”hidden” name=”total_occurrences” value=”1″ />
<input type=”hidden” name=”is_recurring” value=”Y” />
<input type=”hidden” name=”recurring_cycle_1″ value=”365″ />
<input type=”hidden” name=”recurring_cycle_2″ value=”365″ />
<input type=”hidden” name=”recurring_cycle_3″ value=”365″ />
<input type=”hidden” name=”payment_succ_page” value=”https://www.YourSite.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>

If you see the line in bold above, you will see the field…

payment_succ_page

… pointing to the first upsell…

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

What this essentially means, is that once the payment for the front end order is complete, you want the contents of the page /dap/upsell.html to be presented as the first upsell.

So…

a) Either create an HTML page called upsell1.html in the dap folder.

b) Or change the name of the file in the buy-button form code above, to be whatever your actual file name is.

c) Or if you don’t wish to do any upsells, then put the URL of your final thank you page in that field’s value.

2) Question: How do I use my own button with the shopping cart script?

Look for this in the DAP generated button code:
input type=”submit” value=”Buy Now”

Replace it with your own image :
For example –
input type=”image” src=”/images/btn-order.png” value=”Buy Now”

If images folder is at the root of your site, set src = /images/btn-order.png. If it’s under dap folder, the src tag should be set to “/dap/images/btn-order.png”.

This is very similar to Paypal’s Instant Payment Notification (IPN).

The ClickBank INS notification will be processed instantly in real time, and your members will receive their welcome email with their membership login info instantly after purchase.

For high-level ClickBank user-flow, see this post.

CB INS Setup

1. Login to your ClickBank account

2. Go to the “Account Settings” tab at the top

3. Click on “My Site” from the sub-menu at the top.

4. Under Advanced Tools, update the Instant Notification Service URL (accept the terms of service etc), and make sure the URL points to:

http://YourSite.com/dap/dap-clickbank.php

Replace YourSite.com above with your actual domain name.

5.  Screenshot below shows Version 1.0, but starting DAP v4.2, we have added support for CB INS 2.1.

So if you’re using DAP v4.2 or later, then select INS Version 2.0 and set the CB INS URL TO :

http://YourSite.com/dap/dap-clickbank-2.1.php

But if you’re using DAP v4.1 or earlier, then select Version 1.0

and set INS URL TO:

http://YourSite.com/dap/dap-clickbank.php

6. Whatever value you put in the Secret Key field in ClickBank (see image above), put the same value (must be ALL UPPERCASE) in to your DAP Admin Dashboard on your web site, at:

Setup > Config > Payment Processing > Secret Authorization Key used when interfacing with external systems

7. The Product Title in CB must match the Product Name in DAP.

8. The Thank You Page url in CB product settings page, should be set to point a static thank-you page you create in your WordPress blog – something like http://YourSite.com/thank-you/ .

And the page should state something to the effect of…

Thank you for your purchase. The download information for the product you just purchased has been sent to the email id you just use during the purchase.

Please check that email id in a few minutes, and you will see an email from us with your login information.

That’s it!

Testing

Make a test purchase.

If the integration was setup correctly, the user will be registered in DAP.  You will find the user account in the DAP Users > Manage screen and you will find the completed transaction / order details on the DAP Orders page.

If the test order is listed in DAP Orders page, then CB is correctly integrated with DAP.  Check the payment status in DAP Orders page. If it says Success, but no welcome/thank-you email got sent, then make sure you set the thank-you email for that product in DAP products page.

Troubleshooting

If no order is listed in DAP orders page for the test purchase, then CB is not integrated with DAP.

To troubleshoot, do the following:

1. Set DAP Setup > Config > Log Level to 5.
2. Empty log content under System -> Logs.
3. Run another test purchase.
4. Send us the log snippet from System -> Logs.

DAP directly integrates with the following Payment Processors without the need for any additional third-party shopping carts:

• Authorize.net
• 2Checkout.com
• ClickBank
• Digiresults
• Google Checkout
• e-Junkie (e-J does not allow recurring payments)
• JVZoo
• Paypal Standard
• Paypal Website Payments Pro
• Plimus
• WorldPay
• WSO Pro (Warrior Plus)

DAP also integrates with the following Shopping Carts

• 1SiteAutomation.com (a 1shoppingcart private label)
• Premium Web Cart
• InfusionSoft
• WP eStore

Indirect Integration through 3rd Party Shopping Carts

Since DAP integrates with Shopping carts like 1SiteAutomation.com (our white label of 1Shoppingcart), e-Junkie, Premium Web Cart and Infusionsoft, that means that it also integrates (albeit indirectly) with all of the Payment processors and gateways that these carts support. So, or example, since DAP works with 1SiteAutomation, it essentially integrates with all payment providers supported by 1SiteAutomation, like:

2CheckOut.com (direct integration too)
Authorize.net (direct integration too)
Bank of America
BluePay
Concord EFSNet
Cybercash

1-Click Upsells

If you use DAP as a shopping cart, then you can do 1-Click Upsells/Downsells like the pros, without the need for any external shopping cart or upsell service provider.

DAP directly allows you to do 1-Click Upsells using Authorize.net, Paypal Website Payments Pro and Paypal Standard. Upsell-Tree plugin for Authorize.net and Paypal Website Payments Pro is included for free along with your purchase of DAP. However, the Upsell-Tree plugin for Paypal Standard is sold separately.

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

1ShoppingCart & GoDaddy

If you want automated recurring order processing using 1ShoppingCart (1SC) or 1SiteAutomation.com, 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, then because GoDaddy disables a mandatory PHP library (“imap”) on all their servers for some reason, DAP is unable to process the recurring order email notifications from 1ShoppingCart.

This is not an issue if you are using GoDaddy as just your domain name registrar, and using some other service like Dreamhost or Hostmonster as your web host.

But 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.

Please note that 1ShoppingCart order processing works great with all other (non-GoDaddy) 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.
