You can send funds to anyone with an e-mail address, whether or not they have a PayPal account. To receive the funds, though, the recipient must have a PayPal account associated with that e-mail address. Basic PayPal accounts are free, and many financial transactions are free as well, including all purchases from merchants that accept payments using PayPal .
If you have a PayPal account, you can add and withdraw funds in many different ways. You can associate your account with bank accounts or credit cards for more direct transactions, including adding and withdrawing money. Other withdrawal options include using a PayPal debit card to make purchases or get cash from an ATM, or requesting a check in the mail.
PayPal Instant Update API is a feature of Express Checkout that lets customers view postage options, insurance choices and tax totals at the beginning of the checkout process.
Studies show that buyers are more likely to complete checkout when more transaction details appear sooner and when there are fewer steps in the overall process. By providing important transaction details up front, Instant Update API makes checkout faster and simpler – two factors proven to boost customer sales.
Instant Update API supports Real-Time Postage Options. This gives buyers more accurate postage options based on actual cart items and send-to addresses. The feature also supports Flat-Rate Postage Options and third-party postage and tax calculation.
