PayPal Specific Notes

• After 29 days PayPal cancels any authorisation that has not yet been captured.
• After 3 days, an authorisation expires. You can still capture the transaction, but there's a higher risk that the capture is declined, for example due to insufficient funds.
• For refunds of partial captures, each refund cannot be greater than the largest partial capture. For example, if you make two partials captures of $40, and $30, and later want to make a refund of $60- you first have to refund $40, and then $20.
• For addresses in the United States, the Region parameter is represented by a two character ISO abbreviation. For more information, see https://en.wikipedia.org/wiki/ISO_3166-2:US.
• You can only use the same shop_orderid one time, if the transaction was successful.
• The order line items must add up to the amount on the payment.
• Only agreement type recurring is supported.
• For subsequent payments on a recurring agreement order line information should be sent.
