Records a payment — total or partial — on one of the account's invoices, identified by the invoice_id field of the body. An invoice that does not belong to the account is a 404.

The invoice may be in any state — drafts included. When the accumulated payments cover the invoice total, the invoice automatically transitions to paid, whatever its current state.

Send either amount or full: true. With full, the payment settles exactly the outstanding amount, computed when the request executes — use it to settle an invoice without racing other payments recorded between reading the outstanding amount and posting it.

On accounts with an active payment-reporting tax authority the corresponding fiscal report fires automatically. For DGFiP: a domestic French payment emits a CDV 212 lifecycle declaration; a cross-border or B2C payment creates an F10 payment tax report.
