Delphi ActiveX Requires Chilkat v11.0.0+

PayPal: Record a bank transfer against an invoice

See more PayPal Examples

Record USD 45 already received by bank transfer. The invoice may still have a balance. This makes a bookkeeping entry; it does not debit the customer. Save payment_id for reconciliation.
