Obtain payment through PayPal directly from a buyer's credit card.




The DirectPayment component allows you to obtain payment for buyers who do not have a PayPal account. DirectPayment allows you to use your PayPal account as a gateway for any credit card. Your buyer no longer needs to have his own PayPal account.

At the time of this writing, in order to use this component you must have a PayPal Business account to accept direct payments, and you must apply to have "Website Payments Pro" activated on your account. Once that is accomplished and you have set up API access, accepting credit cards is simple. First set the User to your API name, and Password to the password for that API. Set the Signature property to the API signature you received from PayPal. Then you may set the transaction properties, such as : OrderTotal, Number, ExpMonth, ExpYear, etc. Then call either Sale or Authorize. The Ack property will indicate the success or failure of the transaction.

After an authorization, the TransactionId should be saved and logged. This value may be used to capture or void any previous uncompleted Authorize transactions (these functions will not work for a Sale transaction, which is already considered complete).

In addition, this component also provides the results to two anti-fraud measures: Address Verification Service (AVS) and Card Verification Value (CVV) tests. The results of these tests will be stored in the AVS and CVV, respectively. Although a transaction may be authorized, it is up to the merchant to inspect these properties and determine whether or not to honor the transaction.
