Steps
POST /v2/invoicing/invoices with invoice detail, recipient, and item/amount fields to create a DRAFT invoice
POST /v2/invoicing/invoices/{invoice_id}/send to move the invoice from DRAFT to SENT — this triggers PayPal to email the customer a secure link to pay the invoice on PayPal's site
Track status transitions (SENT → VIEWED → PAID, or CANCELLED/OVERDUE) by fetching the invoice or subscribing to PayPal's invoicing webhook events
If the customer paid outside PayPal (check, bank transfer, cash), call POST /v2/invoicing/invoices/{invoice_id}/payments to record that external payment and mark the invoice fully or partially paid; the response returns a payment_id
Use the invoice's refunds sub-resource to record a full or partial refund so the invoice's PayPal status stays accurate even when the money moved outside PayPal
Known gotchas
Recording an external payment via the /payments sub-resource does not move any money — it only updates the invoice's status/paid-amount bookkeeping in PayPal, so it cannot be used to reconcile the actual bank transaction
A DRAFT invoice is not visible or payable by the customer — it must be explicitly sent via the /send endpoint before its payment lifecycle (and any due-date clock) starts
