    MyInvois UUID

    A universally unique identifier issued by Malaysia's LHDN MyInvois portal for each validated e-invoice. The UUID — together with the embedded QR — is the buyer's proof that LHDN has validated the invoice.

    More Details

    The UUID is returned synchronously when the seller submits a UBL 2.1 XML or JSON payload to the MyInvois API with a valid LHDN-onboarded digital certificate. The 72-hour cancellation window applies from UUID issuance; after that, a credit note is required to reverse the invoice.
