| − | [[MW:Extension:PayPal]] is an extension for creating PayPal donation forms using a <paypal> tag. [http://www.rentacoder.com/RentACoder/SoftwareBuyers/ShowBuyerInfo.asp?lngAuthorId=1573573 PokerCoder] requested adding IPN support to the extension through [http://www.rentacoder.com/RentACoder/misc/BidRequests/ShowBidRequest.asp?lngBidRequestId=816040&txtForceRefresh=1129200723554297227 this RentACoder job] and has accepted [[User:Nad]]'s bid to complete the work.

| − | '''I'''nstant '''P'''ayment '''N'''otification, included with Website Payment products, Express Checkout, and Standard Checkout, is available to PayPal Premier and Business members. Instant Payment Notification allows you to integrate your PayPal payments with your website's back-end operations, so that you get immediate notification and authentication of any PayPal payments and disputes you may receive.
| + | NZPost do [http://www.nzpost.co.nz/Cultures/en-NZ/ProductsAndServices/P/PrezzyCard/AboutPrezzyCard.htm Prezzy Cards] and [https://www.loadedcard.co.nz/ Loaded Cards] which work like a normal VISA credit card, but are pre-paid. The Prezzy cards are anonymous, but the Loaded Cards are registered to a particular person and require ID to aquire (but there are no credit restrictions), so they should be able to be used for account verification for PayPal users who with bad credit ratings. |
| | + | *According to [http://smilecity.co.nz/benefits.asp?go=forum&tp=165801&ca=8 this comment] Loaded cards are accepted by PayPal |

| − | When a customer makes a payment to you, PayPal will post a notification to your server at a URL you specify. Included in this notification will be all of your customer's payment information (e.g. customer name, amount) as well as a piece of encrypted code. When your server receives a notification, it will then post the information, including the encrypted code, back to a secure PayPal URL. PayPal will authenticate the transaction by checking the encrypted string. This post-back of the IPN data to PayPal prevents "spoofing," so you can be sure that the IPN came from PayPal. Upon verification, PayPal will send confirmation of its validity back to your server.
