Create invoice draft POST

Creates a CFDI draft and derives canonical line taxes. For each partial payment, increase installment, use the preceding remaining balance as previousBalance, and use taxes: "auto" when Exac knows the related CFDI; otherwise provide its taxObject and payment-level taxes.

Update invoice draft PUT

Fully replaces a CFDI draft and re-runs the same canonical tax resolution used at creation.
