PayPal: Revise a draft invoice from its full billing record

See more PayPal Examples

PUT replaces the invoice. This example revises the quantity on the simple two-inspection draft to three. Rebuild the complete editable document from your billing record; omitted items, terms or recipients can be lost. Do not use this body for an unrelated invoice.
