Payment Details Type Fields
When implementing parallel payments, you can create up to 10 sets of payment details type
parameter fields, each representing one payment you are hosting on your marketplace.
BUTTONSOURCE (Optional) Identification code for use by third-party applications to identify
transactions.
Character length and limitations: 32 single-byte alphanumeric characters
Field Description
PAYMENTREQUEST_
n_AMT
AMT (deprecated)
The total cost of the transaction to the buyer. If shipping cost (not applicable to
digital goods) and tax charges are known, include them in this value. If not, this
value should be the current sub-total of the order. If the transaction includes
one or more one-time purchases, this field must be equal to the sum of the
purchases. Set this field to 0 if the transaction does not include a one-time
purchase such as when you set up a billing agreement for a recurring payment
that is not immediately charged. When the field is set to 0, purchase-specific
fields are ignored. You can specify up to 10 payments, where
n is a digit
between 0 and 9, inclusive; except for digital goods, which supports single
payments only. For digital goods, the following must be true:
total cost > 0
total cost <= total cost passed in the call to SetExpressCheckout
Character length and limitations: Value is a positive number which cannot
exceed $10,000 USD in any currency. It includes no currency symbol. It must
have 2 decimal places, the decimal separator must be a period (.), and the
optional thousands separator must be a comma (,).
AMT is deprecated since version 63.0. Use PAYMENTREQUEST_0_AMT instead.

n_CURRENC
YCODE
CURRENCYCODE (deprecated)

You can specify up to 10 payments, where
n is a digit between 0 and 9,
