What is the MyInvois validation link format?

It is {portalBaseUrl}/{uuid}/share/{longId} with no query string — production uses https://myinvois.hasil.gov.my and the sandbox uses https://preprod.myinvois.hasil.gov.my. The QR on a validated invoice encodes this full URL as plain text.

Is the UUID a normal UUID?

No. The MyInvois document UUID is 26 uppercase Latin alphanumeric characters (a ULID/Base32-like id), not a hyphenated 36-character RFC-4122 UUID. The tool validates it as exactly 26 characters of A–Z and 0–9.

A unique long temporary id returned only for valid documents, used to view the document anonymously via the shareable link. It is an opaque, case-sensitive alphanumeric token, typically 40+ characters, with no fixed length.

Why does it warn about the host?

The validation link must use the portal host (myinvois.hasil.gov.my), not the System-API host (api.myinvois.hasil.gov.my) — a common mix-up. The tool flags that and infers the intended environment.

Is my link or QR uploaded anywhere?

No. Link parsing, QR image decoding, and QR generation all run locally in your browser — nothing is sent to a server.

About

About MyInvois Validation QR Decoder & Builder — LHDN e-Invoice

Malaysian developers building POS or invoice-print pipelines against LHDN e-invoicing need to work with the MyInvois validation link that appears as a QR on every validated invoice. The link follows a strict grammar — {portalBaseUrl}/{uuid}/share/{longId} — and the QR simply encodes that full URL as plain text. This tool parses the link into its parts, validates the UUID and longId structure, and tells you whether it points to production or the pre-production sandbox.

Three modes. Decode a link: paste the URL and see the environment, the 26-character document UUID, and the longId, with any structural problems flagged — including the common mistake of using the System-API host (api.myinvois.hasil.gov.my) instead of the portal host. Decode a QR image: drop in a screenshot or photo of the QR and it is read locally and parsed the same way. Build: pick the environment, enter the UUID and longId, and get a valid link plus a freshly rendered QR you can download for printing.

Everything runs in your browser — links, QR decoding, and QR generation are all local, and nothing is uploaded. The UUID is validated as 26 uppercase Latin alphanumerics (MyInvois UUIDs are not hyphenated RFC-4122 UUIDs), and the longId is treated as an opaque, case-sensitive token. It validates structure only; scanning the real link is what confirms a document with LHDN.
