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.

Agreements with PayPal

• Only the recurring ones are supported.
• You should provide us with order line information for the subsequent payments on a recurring agreement.

Seller Protection Notes

You're eligible for this only when providing a shipping address as part of the order lines, and it's applicable when the order consists of physical goods. Keep in mind that the shipping address is not mandatory, so this is opt-in feature.
