Handling Recurring Payments

Recurring Payments With the Express Checkout API

Billing the Outstanding Amount

If a payment fails for any reason, PayPal adds the billing amount (including shipping and tax,

if applicable) to the profile’s outstanding balance. Use the AUTOBILLOUTAMT field in the

CreateRecurringPaymentsProfile request to specify whether PayPal should add the

outstanding amount to the payment amount for the next billing cycle.

Whether or not you choose to include the outstanding amount with the payment for the next

billing cycle, you can also use the BillOutstandingAmount API to programmatically

collect that amount at any time.

Identifying Items as Digital or Physical Goods

Set all the payment details item fields in the following table in the

CreateRecurringPaymentsProfile request. If all items are digital goods, be sure to set

the item category field to Digital to get the discount rate for digital goods.
