Brought from: http://salearningschool.com/displayArticle.php?table=Articles&articleID=1283&title=Automating%20Digital%20Delivery%20with%20Paypal%20Payment%20Processing%20System

the time-period: 2007 – 2008

In the past, I implemented an automatic notification and digital product delivery system with Paypal Payment Processing System. The concept is, when a person buys products from your web-sites, he gets his products automatically as email attachments after you have confirmed the transaction. The most important part is – collecting payment data and buyer information from Paypal to ensure that the transaction is legitimate and the payment really went through. You can use either Paypal IPN or Paypal PDT to collect these data and email products on successful verification. Either will/should work. For me, PDT worked alright. Check the following web-pages/documents. Also, from PDT section, check the sample examples. For me the sample example with ASP/VBSCript worked alright.

• Paypal Order Management Guide
• IPN Code Sample
• From the first link, also check PDT code sample

In the past, I have worked with MiraServ, and Moneris payment processing systems. You can find short-notes and video tutorials in this web-site on them. Just search through our web-sites.

A relevant code in ASP is provided below. The code collects the payer’s information just after someone has paid. The code also checks, if the payment was successful, if so prints some details about the transaction and the payer

The flow of actions (in terms of code and operations)

• Create a paypal button, provide return URL for successful payment and canceled payment.
• In your successful payment page, write down the following code
• Your paypal account needs to be configured properly to make the following code work – consult the documents as listed above
• You need to use the authentication code from your paypal account to/in the following code
• The follwing code section

  authToken = "ytrtyrtr45654hgfhgfjhfsfdsfdsfds;ljlk" 'auth code for your paypal account
  	txToken = Request.Querystring("tx") 'as sent from paypal 
  
  query = "cmd=_notify-synch&tx=" & txToken & "&at=" & authToken
  
  	set objectHttp = Server.CreateObject("Microsoft.XMLHTTP")
  	objectHttp.open "POST", "http://www.paypal.com/cgi-bin/webscr", false
  	objectHttp.setRequestHeader "Content-type", "application/x-www-form-urlencoded"
  	objectHttp.Send query
  

  submits to the paypal to grab transaction details. (remember, after payment the control is required to come to this page, then based on authentication code and tx-id, the code grabs detail transaction information)
