Payment Setup and Integration FAQ

Upgrading or Downgrading of Subscriptions

There are two main items that need to be addressed when it comes to a member wanting to Upgrade or Downgrade their Subscription from one membership “level” (a.k.a “Product” in DAP) to another.

1) Modifying the actual recurring payments to reflect the new amount

2) Giving them appropriate access as per the upgrade (or downgrade)

So let’s see how both of these are accomplished.

1) Modifying Recurring Payments

You do need to take some manual action for this. The way to do it is….

Ask your members to sign up for the new product/level/subscription separately, like it were a new sign up
Cancel their old subscription manually. When using Paypal standard, this can be done by both you (as the admin) and the member themselves. But with all of the other payment solutions, you (the admin) will have to log in to the payment gateway (Authorize.net or Paypal Website Payments Pro) and manually delete the member’s old subscription). DAP will not automatically remove users old subscription profile in your payment gateway.

2) Giving your member access to new level

Set up automation rules using DAP’s Product Chaining feature, so that if they sign up for one Product (or “level”), they’re automatically removed from another Product (or level).

So if they are currently signed up to your “Gold Membership”, then when they sign up afresh for the “Platinum Membership”, then set up a Product Chaining rule that says, “If member signs up for Platinum Membership, then remove them from Gold Membership”. This is just to make sure that they don’t have access to two products (or “levels”) at the same time.

DAP Shopping Cart

WARNING

This is the old, deprecated version of the DAP Shopping Cart add-on. This is still here for archive purposes only, and should only be used with DAP versions 4.4.x or EARLIER.

If you are wanting to use the new DAP Shopping Cart Plugin that supports Stripe and has a unified checkout page, etc, then you can download it from http://digitalaccesspass.com/dappers/new-dap-shopping-cart-plugin/

__________________________________________________________

ARCHIVE ONLY:

This plugin replaces ALL files from both the “Paypal Payments Pro” Upsell-Tree plugin as well as the “Authorize.net” Upsell-Tree Plugin

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)

Setting up Paypal IPN

1. Enabling Instant Payment Notification (IPN) within your Paypal account.

a) Log in to your Paypal account and click on the “Profile” link in the menu, then on the next page, click “My selling tools.”
b) Under “Getting paid and managing risk” section, click “Update” beside “Instant payment notifications”

c) If IPN is already enabled, you are all set. If IPN is not already enabled, then click on “Choose IPN Settings”

d) On the next screen, in the Notification URL field, enter…
http://YourSite.com/dap/dap-paypal.php
Don’t forget to replace “YourSite.com” with your actual web site’s domain name.

e) Make sure “Receive IPN Messages” is selected.

f) Click on “Save”.

DAP Login Xpress

What Is “Login Xpress”?

“Login Xpress” is a DAP feature that enables your members to be logged right into your membership site immediately upon completion of their purchase.

This is roughly how it works:

Visitor arrives at your web site
On your sales page, they click on any “Buy” button to purchase a Product (or Membership Level)
They’re taken to the checkout page (depending on Payment processor being used) and they enter their payment information and hit “Submit”
When they hit “Submit” to complete their payment, their payment is processed right away, and the buyer is immediately transferred back to your web site, in real time, and automatically logged in to your membership site, and they are taken to the “Welcome” page or “Members” page (you may choose what this page is going to be at a per-Product level)

Payment Processors That Work With Login Xpress

DAP supports this feature with the following payment processors:

Paypal Standard (DAP-generated buttons only – will not work with Paypal-hosted buy buttons that you generate from within your Paypal account)
1Shoppingcart / 1SiteAutomation.com
Authorize.net

If you use any of the payment options above, then you can set up your sales funnel in such a way that buyers are logged in right away immediately after purchase.

Payment Processors That DO NOT Work With Login Xpress (Yet)

Paypal Website Payments Pro
ClickBank
e-Junkie
WorldPay

DAP integrates with the above processors via some kind of “back-end payment notification” – similar to Paypal’s “IPN” (Instant Payment Notification). Which means the notification between the payment processor and DAP on your site only happens on the “back-end”. Which is why DAP can only deliver the login details to the buyer via an email, and cannot log them in right away (like it can do with “Login Xpress”), because the buyer’s information is available to DAP only when the payment processor sends out the IPN notification behind-the-scenes, so to speak.

So if you’re using the above processors to accept online payments, then what you need to do, is to redirect your buyers to a static “Thank You” page that has a message similar to the one below…

“Thank you for your purchase. In a few minutes, please check your email address used during purchase for your log in details to log in to the members’ area and access the product you just purchased.”

And behind the scenes, DAP would’ve already received the payment notification from the payment processor, and it would’ve created an account for your buyer, given them access to the purchased product, and sent them the “Thank-you Email” for the product(s).

DAP-Generated Paypal Button – FAQ/Troubleshooting

NOTE: If you wish to set up your Paypal IPN URL to be broadcast to multiple sites, you may also consider our IPN Redirect plugin from WickedCoolPlugins.com
_____________________________________________

Question 1A: How can I share one Paypal account with multiple DAP and non-DAP sites?

-OR-

Question 1B: If I use “DAP” generated buy-buttons, and I have to set up the “auto-return URL” in Paypal, which is limited to just one URL. How can I use that if I’m selling from multiple web sites and using the same Paypal account?

Answer: You can share same Paypal account between multiple DAP and other non-DAP sites if you use DAP-generated Paypal buttons or Paypal-hosted buttons or a combination of both.

If you use DAP generated Paypal buttons:

DAP sends button-level return value to Paypal. By default, DAP sets the button level return to point to a DAP script on the site where you generated the button ( http://yoursite.com/dap/dap-thankyou.php ). Upon payment, the users are returned to that dap-thankyou.php. And then the dap-thankyou.php script creates the membership account , auto-logs in users to their membership area and redirects users upon login to whatever you have in DAP product-level or DAP global-level login redirect. So the users automatically land at the ‘DAP product-level or DAP global-level login redirect‘ upon successful payment.

If you want the users to be redirected to a different URL upon login, then you can add a redirect tag to dap generated button code:

The auto-return needs to be set and pointed to some URL – any URL – otherwise Paypal will not be able to automatically return users back to your website upon payment for non-paypal hosted buttons. DAP does not care what you set it to – but if you do set it, then make sure that all the Paypal buttons you use (DAP-generated or Paypal-hosted) have their own auto-return value.

If you use a DAP-generated Paypal button, you do not have to worry about the auto-return URL, because DAP will set it and send it to Paypal at a button level. But if you use Paypal-hosted buttons, then make sure you set the button level ‘return’ value.

If you do not set the button level return value, then the Paypal profile -> global level auto-return will get used. So if your global auto-return (under Paypal -> Profile -> Website Payment Preferences) is set to some URL on Site B and say you use a Paypal button to sell something on SITE A but that paypal button does not have a return value set, then upon purchase, the users will get returned to the URL on SITE B and that is probably not what you want. so make sure you set the button level return value for paypal-hosted buttons.

Question 2:

I added DAP hosted buttons and did a test purchase. After purchase the user was redirected to the login page and but the user was NOT automatically logged in. The login page states: SUCCESS! Thank you for completing the purchase. Please check your email for further details. Have I setup something incorrect?

Answer:

What do you see in DAP Payments/Coupons -> Orders page for this transaction ?

Hit the search button in the orders page and it will bring up all orders.
Is the payment status “Pending” or is it “Complete” ?

If it’s pending, it could be why the user is not getting logged in. Click on the transaction Id hyperlink for that order and it will take you to the transactions page… here you can see what Paypal sent in the transaction blob.

See if Paypal sent Payment Status = pending. It yes, it can happen if the buyer didnot confirm their email in paypal.

But if payment status is complete, then do this.

Set DAP setup -> config -> log level to 5
Then go to dap system -> logs and Empty log content

Then rerun the paypal purchase and send us the log snippet.

Question 3: Users are not getting auto-logged in.

I see these errors in the dap log.

>> 2011-03-29 10:54:02:dap-thankyou: after fopen
2011-03-29 10:54:02:dap-thankyou.php: paypal communication failed <<

Answer: In dap-thankyou.php script, dap uses fopen to connect to paypal to retrieve purchase details and to auto-login users.

If it is failing, then there is probably a fopen connection issue between your host and paypal.

Try this:

In dap config -> payment processing -> Set “Use CURL to connect to Paypal” to FOPEN.

If you set it to fopen, the the IPN script (dap-paypal.php) will use FOPEN to talk to Paypal also. Otherwise it will use CURL.

If the dap-paypal.php (backend ipn script) works, the user account will get created successfully in DAP but for auto-login to work, the front-end script (dap-thankyou.php) needs to work. But for front-end dap-thankyou.php script to work, FOPEN needs to work on your server/host.

So to test if FOPEN is working, do this:

Set DAP setup -> config -> log level to 5
Then go to dap system -> logs and Empty log content

Make the backend IPN script also use FOPEN (by setting dap config -> “Use CURL to connect to Paypal” to FOPEN)

Now rerun purchase and see if you notice dap-paypal.php lines in there with fopen communication error in DAP Logs.

If yes, then the problem is that your host is preventing fopen communication with paypal.
If no, then open a ticket with us and we will look into it.

Question 4: How do I replace the DAP generated PP button with my own image?

Look for this line in the button code:

Replace the “src” tag with the path to your own image file.

Ex – <input type=”image” src=”/dap/images/myimage,gif” border=”0″ name=”submit” alt=”Make payments with PayPal – its fast, free and secure!” />

Question 5: How to redirect Paypal buyers to a custom URL after purchase?

Answer:

If you’re using buy button form code, then you can add a redirect tag to dap generated buy button code:

If you are using a buy button link, then add the text below at the end of your link.

&redirect=http://yoursite.com/thankyou/

Like this:

http://YourSite.com/dap/paypalCoupon.php?cmd=_xclick-subscriptions&item_number=10&currency_code=USD&redirect=http://yoursite.com/thankyou/

http://YourSite.com/dap/paypalCoupon.php?cmd=_xclick-subscriptions&item_number=10&currency_code=USD&redirect=/thankyou/

DAP IPN Script Generator – 3rd party Shopping Cart integration

While DAP already supports a large number of shopping cart systems and payment providers, if you wish to integrate DAP with one that we don’t support yet, then you can custom create DAP integration for any 3rd party shopping cart providers that support Instant Payment Notification (IPN) via HTTP POST to 3rd party scripts.

NOTE: While you’re welcome to use the documentation below and develop your own custom integration with any payment processor that supports IPN, during development if you need our support, then we charge an hourly fee if you want help with your code.

Instant Payment Notification (IPN)

Instant Payment Notification (IPN) is basically a message service provided by a shopping cart service or payment processor, that enables them to notify third-party systems like DAP about events related to Payment transactions. You can use it to automate membership sign-ups and cancellations, and extend membership access (for recurring products).

Paypal pioneered the concept of IPN, and different systems may have a different name for it (for eg., ClickBank calls it “INS – Instant Notification Service”). But they all essentially mean the same.

So, using IPN, the cart/processor notifies DAP when a payment-related event occurs. Typically, these events represent various kinds of payments. The notification includes info about the buyer’s email id, product name purchased, product price, payment status etc.

And you can use the DAP IPN Generator script below to generate a PHP script that can receive (and understand) the IPN notification from your cart/processor.

DAP – IPN Script Generator

DAP provides the ability to generate an IPN Script/handler for any 3rd party shopping cart that support IPN. Once the script is generated, upload it to the dap folder on your site and update the shopping cart IPN URL settings with the URL to this script.

1) Go to DAP Admin > Setup > Generate IPN Script

2. Fill in the boxes with the exact TAG NAME / FIELD NAME that your shopping cart sends for each of the fields listed there.

Say that in the IPN notification, your shopping cart sends the product name in the tag/field called item_name. Then you need to enter item_name in the product name text box.

The transaction type indicator tells DAP what type of transaction it is… whether it’s an add-to-cart or buy now or subscription type of transaction. The tag name itself goes into the Transaction Type text box but the actual value for each type (buynow, cart, subscription) goes into the text boxes that say BUY NOW, Subscription, AddToCart.

In the text box in the picture above, the value of ‘Sale’ is an example value that a shopping cart might send to identify a ‘buy now’ transaction/button. Check your shopping cart’s IPN documentation and make sure you fill in the right values in each of the text boxes in the dap generate ipn page.

3. After filling up all the text boxes, hit the ‘Generate IPN’ button. It will open a small window with the actual dap IPN script.

Copy the whole script and put it in a file and lets say you call this file – dap-IPN-script.php.

Upload this file to the dap folder on your site.

4. Go back to Generate IPN Page in your DAP admin panel.

Now click on the ‘Test IPN Script’ button at the bottom. It will bring up a form where you can fill in actual values (you can give this form to your shopping cart provider so they know what fieldnames/tags to send to dap ipn handler/script). In the IPN URL text box, put in the full URL of the IPN Script you generated in step 3 (for ex – http://yoursite.com/dap/dap-IPN-script.php).

Run the test. It will simulate a real purchase transaction by a buyer and show you how DAP automatically manages the creation of membership account upon successful purchase.

>> 3. After the customer makes the purchase I want them added to my Aweber auto responder. < <

Please see: http://www.digitalaccesspass.com/doc/aweber-integration/ For paid products, always integrate DAP -> Aweber.
For free products, you can use either aweber webform -> DAP OR DAP direct signup form -> aweber.
If you want to use aweber -> DAP, use http://www.digitalaccesspass.com/doc/use-aweber-webform-to-signup/
If you want to use DAP -> AWeber, use http://www.digitalaccesspass.com/doc/aweber-integration/

>> 4. People sign-up with their email through an Aweber sign-up form. At the end of a few dripped emails using Aweber they can buy a low-priced product. Whats the best way to set this up ? <<

Create a free product in DAP.
Use Aweber webform -> DAP to integrate aweber free list to DAP free product.
When the users signup using the aweber free form, they will also be signed up in DAP.
Encourage these users to update their paypal email address in their DAP userprofile after they become member that way when they become paid members (applies to payment via Paypal only), DAP will add the paid product under the same user account under which they had free product.
See – http://www.digitalaccesspass.com/doc/use-aweber-webform-to-signup/

Create the paid product in DAP.
Integrate DAP with the payment processor so when they purchase the product, DAP will be notified and the user account will be created in DAP.
Update the 3rd party notification field in DAP products page to notify the paid aweber list.
Add product chaining rule in DAP to remove access from free product when the user gets access to the paid product.
Add rule in aWeber to automatically remove user from free list when they get added to paid list.
When the user makes purchase, DAP will add the new product to their existing account, remove free product from their account, add them to the new aweber list and aweber will remove them from the free list.

>> 5. There are two subscription products: Monthly ($10, recurring) and Annual ($100, Recurring). A subscriber tries Monthly for two month and then decides to “upgrade” to an Annual subscription, which is cheaper in the long-run. Is there a way to automate this for the subscriber’s choice?

Answer:

Create 2 products in dap – monthly subscription and annual subscription product

The recurring settings for monthly will be as shown below:
http://screencast.com/t/UinkvvTq

The recurring settings for annual will be as shown below:
http://screencast.com/t/TG6zzTVx

Setup product chaining rule in dap to automatically remove user’s access to monthly product if they subscribe to annual.

1) user purchases monthly product
They will get 30 days access initially. When the next payment comes in at the end of the month, dap will extend access by another 30 days.

2) now after the user purchases monthly product, they want to upgrade to annual payment option.
They will click on the buy button to complete purchasing the annual subscription.
DAP will now give them access to the annual product with a start date of current date and end date of 365 days from today.
The product chaining rule will trigger and dap will remove this user’s access to monthly product. So now in manage users page, you will see the user is tied to annual product and not the monthly product.

You do need to take some manual action in this scenario. You will have to login to the payment gateway (authnet or paypal) and remove the users old subscription to monthly). DAP will not automatically remove user’s monthly subscription profile in the payment gateway.

>>6. How do i make sure the email drip feed via DAP autoresponders are working?

Add a new user via DAP admin panel
Wait for the top of the hour for cron to run
Then check the user’s email box at the top of the hour to see if the day-1 drip emails went out.

If the user is on say day 2 of membership… then they will receive the day 2 drip emails at midnight (server time) because when the cron runs for the first time for that day (at midnight), it will pick up all users that are on day 2 of their membership and send out day 2 emails.

>> 7. All of the products are in one file called DLmmmDL. All files in this folder are zipped. The file is located where dap was installed. I want this file and the files in it protected. < <

If you have a wordpress site, ideally you should upload the files that you want to protect under /wp-content/uploads folder. You can create a subfolder under uploads and upload the files there. DAP looks under /wp-content/uploads folder by default for file protection. After uploading files under /wp-content/uploads, go back to dap products page and protect the full URL of each zip file. See – http://www.digitalaccesspass.com/doc/protecting-regular-site-files/ >> 5. I want an affiliate section to where people can sign up and sell my products. I dont see where to create a link in my footer that says affiliates. < < You can update the theme footer to include the hyperlink of your affiliate signup page. See – http://www.digitalaccesspass.com/doc/instant-affiliates/ >> 6. Of course it needs to send an email to the customer once they pay so they can download their products. <<

Paypal Integration Summary

DAP supports 3 different types of Paypal Integration.

1) Paypal Hosted Buttons
2) DAP Generated Buttons For Paypal
3) DAP Shopping Cart with Upsells

Let’s get into more details about each one of them.

[s3mv]DAP-Paypal-Integration-Overview.mp4,640,350,false,false[/s3mv]

1) Paypal Hosted Buttons

You generate the button within your Paypal account.

Click Here to find instructions to integrate DAP and Paypal Hosted Buttons.

If the integration is not working, Click Here to find troubleshooting instructions.

Note: you only need to set the following config items for Paypal hosted buttons.

a) If you want to use Paypal Sandbox for testing, then set the following to “Y”.
DAP Setup -> Config -> Paypal -> Use Paypal Sandbox: For initial testing only

If you want to connect to your Paypal live account, then set it to “No”.

b) If your site has trouble connecting to Paypal via CURL and you see this error in DAP orders page => Check Product and Price(Reprocessible), then update the config below to FOPEN.

DAP Setup -> Config -> Paypal -> 4) Paypal Communication Protocol: How DAP connects to and communicates with Paypal on the back-end.

That’s it.

The following config items are NOT needed if you use the Paypal hosted buttons.

Paypal API Username – Only needed if you use the DAP upsell tree plugins for Paypal Payments Pro or Paypal Standard.
Paypal API Password – Only needed if you use the DAP upsell tree plugins for Paypal Payments Pro or Paypal Standard.
Paypal API Signature – Only needed if you use the DAP upsell tree plugins for Paypal Payments Pro or Paypal Standard.
Paypal API Endpoint – Only needed if you use the DAP upsell tree plugins for Paypal Payments Pro or Paypal Standard.

Paypal Business Email ID – Only needed if you use the DAP generated button for Paypal (DAP Payments/Coupons -> Generate paypal button)

Merchant Payment Gateway API Login ID: Only needed if you use e-junkie or the DAP upsell tree plugin for Authorize.net
Merchant Payment Gateway Transaction Key: Only needed if you use e-junkie or the DAP upsell tree plugin for Authorize.net

The following fields in the DAP Products page ONLY need to be set if you use DAP upsell tree plugin or the DAP generated button for Paypal.

Recurring Count, Trial Amount and Product Price

If you are using regular paypal button, you can leave these empty. Even if these are not-empty, DAP will not use it for regular paypal hosted buttons.

2) DAP Generated Buttons For Paypal

With DAP 4.0, we have added support for DAP generated buttons for Paypal. You no longer have to generate buttons within Paypal.

You can generate the button for Paypal from within your DAP Admin Panel -> Payment Processing -> Generate Paypal Button page.

Click Here to find instructions to integrate the DAP generated button with Paypal.

3) DAP Shopping Cart / DAP Upsell Tree Plugins

1) Paypal Standard Upsell Tree Plugin
2) Paypal Payments Pro Upsell Tree Plugin / DAP shopping cart

Click Here for details.

Troubleshooting Paypal Hosted Button Integration

1) I got an e-mail with this subject:
[DAP] http://yoursite.com: dap-paypal: Invalid IPN Coming In

This can happen if you click on this URL in a browser.

http://yoursite.com/dap/dap-paypal.php (replace yoursite.com with the name of your site).

This is a backend script and should not be called directly via browser. But if you click on this accidently, this error can be ignored. Just make sure that the DAP and Paypal are integrated and purchases via Paypal are getting registered in dap correctly.

2) DAP Paypal IPN Error (Rejected): IPN Product Name = does not match any DAP Product Name.
But REJECTING MISMATCH it because of your Config settings (Product Mismatch)

Make sure that the item_name in Paypal button is set to eXactly match a DAP product name otherwise DAP cannot process the payment notifications. If the notification is for a product that you sell outside of DAP, then DAP will reject it with this error message and no action is needed.

If you want DAP to process Paypal notifications even if the product name in DAP does not match the Paypal item_name, then enable this setting in DAP :

DAP Setup -> Config -> Payment Processing -> Should DAP process Customer Emails even when the Product names don`t match ->
Set this to “Y” if you want DAP to process non-dap defined product purchase notification from Paypal.

3) Paypal failing with “Check Product and Price(Reprocessible)” in DAP Orders page

Note: DAP Orders page moved under Payment/Coupons menu in DAP 4.0

This could be due to a problem with the CURL library on your site.
With DAP 4.0, you can easily switch your site to use FOPEN instead of CURL.

DAP Setup -> Config -> Payment Processing -> How DAP connects to Paypal -> Select FOPEN

4) Can I use my Paypal account to sell products outside of DAP even if the global IPN points to a DAP script?

Sure. Paypal has 2 IPN settings:

a) Local button level IPN
This one needs to point to the DAP script (http://yoursite.com/dap/dap-paypal.php) on your site so for all sales via this button,
Paypal can send a notification to DAP.

b) Global IPN – under your Paypal profile -> instant payment notification preferences
This one is used by Paypal ONLY if button level IPN is not set. If the button level IPN is set, then Paypal ignores the global IPN.

We recommend that you set both button level and global IPN to point to the same dap script –
http://yoursite.com/dap/dap-paypal.php
(NOTE: replace yoursite.com with the name of your site)

Now, if you are selling other products outside of DAP using Paypal and for those Paypal buttons, if there is no button level IPN notification defined, then Paypal will look at the global IPN setting (which also points to dap) and send notifications to dap. But dap will reject that message because the product is not defined in DAP.
That is when you receive these ‘IPN rejected’ messages and you can ignore them.

5) I have integrated DAP and Paypal per your documentation but it still does not work.

Three key things to watch out for when you integrate DAP and Paypal are:
a) Make sure that the Paypal button has the item_name set to exactly match a DAP product name otherwise DAP cannot process the payment notifications.

b) Button-level IPN must point to DAP script (http://yoursite.com/dap/dap-paypal.php – replace yoursite.com with the name of your site).

In Paypal button creation page, under Ã¢â‚¬Å“Step 3: Customize advanced features (optional)Ã¢â‚¬Â tab, within the Ã¢â‚¬Å“Advanced VariablesÃ¢â‚¬Â text box,
enter the following (change the text yoursite.com below to your domain name).

notify_url=http://yoursite.com/dap/dap-paypal.php
Note: replace yoursite.com with the name of your site

c) Global IPN must be enabled and pointed to the DAP script as descrbed in step 1 of this document.
http://www.digitalaccesspass.com/doc/setting-up-your-paypal-button-and-paypal-IPN/

6) What config items in DAP are required if I use Paypal HOSTED button?

If you want to use sandbox for testing, then
DAP Setup -> Config -> Payment Processing -> Use Paypal Sanbox For Testing -> Set to “Y”.

If your site has trouble connecting to Paypal via CURL and you see this error in DAP orders page – Check Product and Price(Reprocessible), then update the config to use FOPEN.

DAP Setup -> Config -> Payment Processing -> How DAP connects to Paypal –> Set to “Y”.

NOTE: In the DAP Products page, you ONLY need to set the Product Price, Trial Amount and Recurring Count if you use the DAP hosted/generated buttons for Paypal. Not needed if you use Paypal hosted buttons. You can leave it empty if you use Paypal hosted buttons. Even if you populate it, it will not be used.

If you use the Paypal hosted buttons, then you DO NOT need to set the following in DAP Setup -> Config -> Payment Processing ->

Paypal Business Email ID – Only needed if you use the DAP generated button for Paypal (DAP Payments/Coupons -> Generate paypal button)

Merchant’s Payment Gateway API Login ID – Only needed if you use e-junkie or the DAP upsell tree plugin for Authorize.net
Merchant’s Payment Gateway Transaction Key – Only needed if you use e-junkie or the DAP upsell tree plugin for Authorize.net
==========================================================

Please check all of the steps at the link below…
http://www.digitalaccesspass.com/doc/setting-up-your-paypal-button-and-paypal-ipn/

Especially check the “notify_url” part towards the end.

If you are absolutely sure that you have followed all of the steps above, and DAP is still not creating an account for the new user, it is possible that your host is not allowing your server and Paypal to communicate correctly. You can confirm if this is an issue, by going to the “Orders” page, searching for all orders, and see if your test purchase in question has been recorded by DAP (even if DAP didn’t give access to the user).

If you find the order in DAP, but the user has not been created, then check with your host and make sure “fopen” or “curl” is enabled for your web site.

If they say it is enabled, and it still doesn’t work, please do the following:

1) Go to Setup > Config > Dap Log Level and set it to “5”.

2) Completely delete test user from DAP

3) Repeat test purchase

3) Go to System > Logs and copy/paste the information there into a support ticket

4) And then please update the ticket with…

* Domain name where DAP is installed
* FTP info
* DAP admin info

And we’ll investigate this asap.

5) Go to Setup > Config > Dap Log Level and set it back to “1”.

Troubleshooting 1ShoppingCart Integration

There are a few different reasons why this may not be working.

1. Check if Cron is running

The DAP email-processing cron that processes the 1SC emails may not be running. Check your webhost control panel -> Cron job settings. Make sure dap-emailorder.php is setup to run once every 10 minutes.

2. Incorrect Setup of Billing Email Id

The billing email id you have entered in DAP at Setup > Config > Payment Processing , should be entered into the “Order Notice Email – Primary Destination” field in your 1SiteAutomation/1Shoppingcart account, on the Setup > Orders > Notifications section. If by chance you enter it into the “Order Notice Email – Primary Destination” field, it WILL NOT WORK.

3. No Notification Emails from 1SC

The DAP cron is running but 1SC payment notification emails are not reaching your mail server. Check the email account where you expect to receive your 1SC payment notification emails and see if the order notification email from 1SC is in that mail box.

4. Incorrect Mail Server Settings

The cron is running and the 1SC order notification email is reaching your mail server – but you did not configure the mail server settings correctly in DAP Dashboard -> Setup -> Config -> Payment Processing.

Email Server Where Order Emails Come In
Email Server User Name
Email Server Password

5.”Read” Or Deleted Emails

DAP only processes order notification emails that are in the “Unread” status, to prevent previously processed emails and other non-DAP emails from being repeatedly processed.

Also, if you “pop” off the emails from that mail box (means, your email client like Outlook or Thunderbird or Gmail is “removing” your emails from the server when it retrieves them), it means that when DAP logs in to that billing email address, there are no emails there to be processed – the mailbox is empty, or the 1SC payment notification emails have somehow gotten deleted from that mailbox.

So it is possible that DAP is able to connect to your email server, but DAP is not finding any “unread” emails. Please login to your email server and mark all the payment emails that you want DAP to process… as “unread”. And also make sure that your email client does not remove the emails from that mail box.

6.Product Name Mismatch

There might be a “Product Name” mismatch. The product name has to be EXACTLY the same (including case, spaces, etc) in both DAP as well as in 1ShoppingCart. So if you have created a product by name “Widget A”, make sure your 1shoppingcart product also has the exact same name “Widget A”.

If everything is setup correctly, DAP cron will run every 10 minutes and try to process all 1SC emails.

The next time the DAP cron will run (every 10 minutes), it will pick up all the unread payment emails from 1SC.

7. Empty “Thankyou-Email Body/Subject”

Welcome email is not getting sent.

Select the product, and make sure there is some text in the “Thankyou-Email Subject” and “Thankyou-Email Body”. Whatever is in these fields is what gets sent immediately after someone purchases that product (or right after you give them access from the backend).

Now go to DAP Dashboard -> Users -> Add .

Select the product and manually add user. Now see if the thankyou email gets sent to that email id. If it got sent, then your product setup is correct.

Also check the DAP Dashboard -> Orders . Search for all orders, look up the order for the particular user in question by email.

Check the payment status and make sure there is no error there.

If you did all this and things are still not working, please do this:

1. Set DAP Dashboard > setup -> Config -> Log Level -> Log All activity
2. Re-run the 1SC test purchase
3. Check the DAP Logs (DAP Dashboard > System > Logs) and send us the log text in there for troubleshooting by pasting it into a new support ticket.

8. Sending Email & Password To Buyer

Make sure you have set the thank-you message with the right merge tags for Email and Password.

9. Manually Running Cron

First set DAP Dashboard > setup -> Config -> Log Level -> Log All activity

If you feel that the orders were not processed in dap, then just login to the 1SC email account where the sales/payment notification emails are sitting, and mark those orders/emails as UNREAD that you want dap to process.

Then manually run the cron script dap-emailorder.php cron by visiting the following link in the browser.

http://www.yoursite.com/dap/dap-emailorder.php

Replace yoursite.com with the name of your site.

It will just display an empty screen when complete.

Then check “Users > Manage” to see if user has been created.
