Submits the canonical proof requested by an outgoing execution’s nextAction; send exactly that proof type. The Payment must belong to the account fixed by the client bearer token. Escrow-funded Payments use their checkout funding method instead: when no outgoing execution exists, this endpoint returns 409 with reasonCode: payment_confirmation_not_supported. A successful response returns the current Payment and does not imply final settlement.
