Paypal Payment Data Transfer (PDT)

Before talking about PDT, the easiest way to enable paypal integration, use the code below.

<input type="hidden" name="cmd" value="_xclick" />
<input type="hidden" name="business" value="test@test.com" />
<input type="hidden" name="return" value="paymentdone.aspx">
<input type="hidden" name="cancel_return" value="http://cancel.aspx">
<input type="hidden" name="currency_code" value="SGD">
<input type="hidden" name="custom" value="1188967">
<input type="hidden" name="item_name" value="12 months Membership" />
<input type="hidden" name="amount" value="10.00" />
<input type="submit" value="Buy!" />



After user make payment through payment, user is required to click 'Return to seller website'.

If PDT is enabled under your seller profile, it will return tx (txn id) to your designated return page.

The page return from Paypal will contain the parameter in query string as below.

http://YourReturnWebsite.aspx?tx=0YB16486MY080364E&st=Pending&amt=10.00&cc=SGD&cm=1188967&item_number=

cm is the custom parameter that you put in your 'buying' page. This is useful to identify the transaction your customer made.

With the tx (txn id) given, you can do a http post to paypal again to retrieve the txn details, and the response you can get is something like below, which contain the detail of the transaction.
